Performance Marketing: What It Is, How It Works, and How to Make It Profitable

Performance marketing is a digital marketing approach where campaigns are measured and optimised against specific, measurable outcomes such as clicks, leads, sales, bookings, or other conversions. Depending on the channel and campaign model, advertisers may pay for clicks, impressions, or other actions, but performance is evaluated against the business outcome being targeted.

This gives performance marketing a stronger emphasis on measurable outcomes than many traditional advertising models, where businesses may pay for airtime, print space, reach, or impressions without tying the media cost directly to a tracked conversion. The campaign budget is managed around measurable outcomes, with performance data used to determine where spend should be increased, reduced, or redirected.

For Australian businesses evaluating whether to invest in paid digital campaigns, understanding what performance marketing actually involves, how results are measured, what affects profitability, and how to evaluate the agencies offering these services is more useful than a theoretical definition.

What Is Performance Marketing?

Performance marketing can be applied across digital advertising channels when campaigns are structured around measurable outcomes and performance data is used to evaluate and optimise investment. It is not a single channel or tool. It is a discipline applied across multiple channels: paid search, paid social, affiliate programmes, native advertising, and others.

The unifying characteristic is accountability. Every campaign has a defined goal, every result is measured, and the investment is adjusted based on what the data shows.

How Does Performance Marketing Work?

A performance marketing campaign starts with a defined objective. Not a vague goal such as “increase awareness” but a specific, measurable action: generate 50 qualified leads per month at a cost per lead below $80, or achieve a return on ad spend of 4.0 from ecommerce campaigns.

From that objective, the campaign is built backwards. The channel is chosen based on where the target audience is and what intent level they are likely to have. The creative, copy, and offer are built to match the audience’s likely motivation. Tracking is set up to measure the specific action that constitutes success. The campaign launches, data accumulates, and decisions are made based on what the numbers show.

This cycle of define, launch, measure, and optimise is the operating model of performance marketing. It is iterative. The first version of a campaign is rarely the best version. Improvement comes from systematically testing variables and acting on what the data confirms.

Is Performance Marketing the Same as Paid Advertising?

Performance marketing and paid advertising overlap but are not identical. Paid advertising is the mechanism: paying to place content in front of an audience. Performance marketing is the discipline applied to that mechanism, the goal-setting, measurement, attribution, and optimisation that determines whether the spend produces a return.

A business can run paid advertising without performance marketing principles by placing ads without clear conversion goals or measurement. A business applying performance marketing uses paid advertising as the delivery vehicle but evaluates every decision against a commercial outcome.

Performance Marketing Channels

Performance marketing operates across several distinct channel types. Each has different strengths, different audience characteristics, and different cost structures.

Paid Search (Google Ads)

Paid search places ads in front of people who are actively searching for something. When someone searches “plumber Wollongong” or “accountant for small business,” paid search campaigns can place a relevant ad at the top of those results.

Because search captures people who are actively looking for a product or service, it can be particularly effective when there is strong commercial intent and sufficient search demand. A person searching for a specific product or service has already moved past the awareness stage. They are actively looking. The ad appears at the moment of maximum relevance.

Google Ads is a major paid search platform used by Australian businesses. In many Google Search campaigns, advertisers pay when someone clicks an ad, while bidding and campaign optimisation can be focused on conversions or conversion value. The cost per click varies substantially by industry and keyword competition.

Google Ads operates within a performance marketing framework because clicks, leads, and sales can be tracked back to specific keywords, ads, and campaigns, subject to the accuracy of conversion tracking and the limitations of attribution. The cost of acquisition can be calculated, compared against the revenue generated, and optimised accordingly.

Social Media Advertising (Meta Ads and Others)

Social media advertising can be used within a performance marketing framework when campaigns are structured around measurable outcomes and evaluated against those results. It reaches audiences based on who they are rather than what they are searching for. Facebook, Instagram, LinkedIn, and TikTok allow advertisers to target by demographic profile, interests, behaviour, and past interactions with the business.

Meta Ads (Facebook and Instagram) operates within a performance marketing framework when campaigns are structured around defined objectives, whether leads, purchases, or traffic, and outcomes are measured against those objectives. Advertisers can measure cost per lead, cost per purchase, and return on ad spend at a campaign level, though the accuracy of these figures depends on how conversion tracking is configured and the attribution model in use.

The difference between paid search and social advertising is intent. Search captures people who are actively looking. Social reaches people who are not yet searching but match the profile of someone likely to be interested. This makes social advertising effective for building demand before it exists as explicit search behaviour, and for retargeting people who have previously visited the website but not yet converted.

Affiliate Marketing

Affiliate marketing closely aligns with the performance marketing model because affiliates are commonly compensated based on defined outcomes such as sales or leads. The exact payment structure depends on the affiliate programme and agreement, and the level of control over where and how products are promoted varies.

For Australian ecommerce businesses, affiliate programmes through networks like Commission Factory, Rakuten, and Impact are common. For service businesses, affiliate arrangements are less standard but do exist, particularly in financial services, insurance, and education.

Native Advertising

Native advertising places paid content within editorial environments in a format that matches the surrounding content. Sponsored articles on news sites, recommended content links at the bottom of editorial pages, and sponsored posts in social feeds are all native advertising formats.

Native advertising can be used within a performance marketing approach when campaigns are structured around measurable actions and evaluated accordingly. Clicks, time on page, scroll depth, and downstream conversions from native placements can all be tracked. Publishers such as Outbrain and Taboola provide native advertising placements that can be measured against clicks, conversions, and other performance outcomes.

Other Channels

Performance marketing principles can be applied to display advertising (banner ads across web networks), programmatic advertising (automated, real-time ad placement across digital inventory), email marketing through affiliate or commission-based arrangements, and increasingly to connected TV advertising where household-level data allows precise targeting and outcome measurement.

The common thread is not the channel itself but the application of measurable goals, tracking, and optimisation to whatever channel is being used.

Performance Marketing Metrics: What to Track and Why

Understanding performance marketing metrics is necessary for evaluating whether campaigns are working and making decisions to improve them. The most important metrics are not the most complex ones. They are the ones that connect directly to commercial outcomes.

Cost Per Click (CPC)

CPC measures how much each click on an ad costs. On its own, CPC does not indicate whether a campaign is working commercially. The relevant question is whether the clicks being generated are converting at a rate and cost that makes the acquisition economically viable. A low CPC that produces poor-quality traffic may cost more per actual conversion than a higher CPC driving qualified visitors.

Cost Per Lead (CPL)

CPL is the total spend divided by the number of leads generated. For service businesses generating enquiries, CPL can be an important campaign metric, but it should be evaluated alongside lead quality, conversion rate, customer acquisition cost, and eventual customer value. A CPL in isolation does not indicate whether a campaign is commercially viable. A $60 CPL for a business that converts 30% of leads into clients worth $3,000 each is highly profitable. The same CPL for a business with a 5% close rate on $300 products is not.

Cost Per Acquisition (CPA)

CPA measures the total cost to achieve a defined conversion, calculated as total spend divided by total conversions. CPA is particularly useful when the primary conversion is a customer acquisition such as a purchase or another defined customer action. For service businesses where the tracked conversion is an enquiry or consultation, CPL may be more useful at the initial acquisition stage.

Return on Ad Spend (ROAS)

ROAS measures revenue generated relative to ad spend. It is a useful indicator of campaign efficiency but does not determine profitability on its own. Whether a specific ROAS is commercially viable depends on product margins, agency fees, fulfilment costs, and other operating expenses. At 4.0 ROAS, $1 of advertising spend generates $4 in revenue. With a 30% gross margin, that produces $1.20 in gross profit. After the $1 advertising cost, $0.20 remains before other operating costs including agency fees, fulfilment, and overhead. With a 20% gross margin, the $4 in revenue produces $0.80 in gross profit, which does not cover the $1 advertising cost before any other expenses. ROAS must be evaluated against the full margin structure, not revenue alone.

Customer Acquisition Cost (CAC)

CAC is the total cost of acquiring a new customer, typically including relevant sales and marketing costs, divided by the number of new customers acquired. Unlike a channel-level CPA, CAC can account for the broader cost of acquiring customers across the business, making it a more complete measure of acquisition economics. Comparing CAC to customer lifetime value determines whether the acquisition is commercially sustainable over time.

Customer Lifetime Value (CLV or LTV)

CLV is the total revenue or profit expected from a customer over the entire relationship. Knowing CLV helps a business determine the upper limit of what it can sustainably spend to acquire a customer. A business whose customers have high lifetime value can accept a higher initial CPA than one where customers transact once and do not return, though CLV projections are estimates and should be treated as directional rather than guaranteed.

Attribution: How Performance Marketing Measures Across Channels

Attribution is the process of assigning credit to marketing touchpoints that occurred before a conversion. Attribution models indicate correlation between touchpoints and conversions, but they do not by themselves prove that a particular interaction caused the conversion to occur. It is one of the most practically important and most misunderstood aspects of performance marketing.

How Attribution Works

When a customer converts, they have almost always had multiple touchpoints with the business before doing so. They may have seen a Facebook ad, then searched on Google, clicked a Google Ad, visited the site, left without converting, received a retargeting ad, and then purchased a week later. Which of those touchpoints gets credit for the conversion?

The answer depends on the attribution model being used. Attribution approaches have historically assigned credit in different ways, although not all of these models remain available in current Google Ads. Different models assign credit differently, and the model chosen significantly affects how campaigns are evaluated and optimised.

Last-click attribution

It gives 100% of the credit to the final touchpoint before conversion. Under this model, a Google search ad that drove the final visit before purchase receives full credit, even if a Meta Ad drove the initial discovery two weeks earlier. This model tends to overvalue bottom-of-funnel channels and undervalue awareness and consideration channels.

First-click attribution

Gives all credit to the first touchpoint. This overvalues top-of-funnel channels and undervalues the channels that close the sale.

Linear attribution

Distributes credit equally across all touchpoints in the journey. More equitable but does not reflect that some touchpoints have more influence on the conversion decision than others.

Time-decay attribution

Gives more credit to touchpoints that occurred closer to the conversion. This reflects the reality that the final interactions before a purchase are often more influential than early awareness touchpoints.

In current Google Ads, first-click, linear, time-decay, and position-based models are no longer supported. Data-driven attribution is the default for most eligible conversion actions, while last-click remains available.

Data-driven attribution

Uses machine learning to distribute credit based on observed conversion patterns. It can provide a more nuanced view of the customer journey than fixed-rule models, but attribution models still do not by themselves establish whether an interaction caused a conversion. Data-driven attribution does not require a minimum conversion volume to function, but Google says its performance can improve when more conversion and interaction data is available.

The Difference Between Attributed and Incremental Conversions

Attributed conversions are conversions that a tracking system assigns to a campaign based on the attribution model in use. Incremental conversions are conversions that would not have happened without the campaign.

These two numbers are often very different. A retargeting campaign might show high attributed conversions because it appears in the final touchpoint before purchase. But many of those customers may have purchased anyway without the retargeting ad, having already made their decision. The incremental value of the campaign is only the additional conversions it produced above what would have occurred organically.

Understanding this distinction matters for budget decisions. A campaign with high attributed conversions but low incrementality may be generating substantially less additional value than its attributed conversion numbers suggest. Measuring incrementality often involves experiments such as holdout or control-group tests, where conversion outcomes are compared between exposed and unexposed audiences. There are multiple approaches depending on the channel and available data.

Conversion Delays and Their Effect on Reporting

A conversion delay occurs when a user sees or clicks an ad but does not convert for days, weeks, or sometimes months. This is common in B2B, high-value service purchases, and any category with a longer consideration cycle.

Conversion delays affect performance reporting because campaigns appear to be underperforming in the short term while conversions from earlier activity continue to arrive. A campaign paused prematurely because the first two weeks showed weak results may have been generating qualified prospects who converted in the following weeks without any credit being allocated.

Looking at longer reporting windows, comparing performance across consistent time periods, and understanding the typical lag between first interaction and conversion in a specific category all help account for this effect.

Why Meta and Google Report Conversions Differently

When Google Ads and Meta Ads both have opportunities to attribute the same conversion, their reported conversion totals can overlap because each platform applies its own attribution and measurement rules. The figures therefore should not simply be added together to calculate total business conversions.

Cross-referencing platform data with analytics, CRM records, and actual sales figures can provide a more complete view of how marketing activity contributed to business results.

Conversion Tracking: The Foundation of Performance Marketing

Conversion tracking is the technical setup that records when a user completes a desired action after interacting with an ad. Without accurate conversion tracking, a performance marketing campaign cannot be reliably optimised. Every optimisation decision, from bid adjustments to audience refinements to budget allocation, depends on the tracking data being correct.

Conversions can be defined differently depending on the business and campaign objective. Common conversion types include:

• Form submissions and enquiry completions.
• Phone calls tracked through dynamic number insertion.
• Ecommerce purchases.
• Bookings through scheduling tools.
• App installs.
• Qualified leads defined by specific criteria.

For businesses with longer sales cycles, offline conversions can be imported back into the ad platform.

This allows the campaign to be optimised toward actual sales outcomes rather than only the initial enquiry, which is particularly relevant for service businesses and B2B where the gap between enquiry and purchase can be weeks or months.

Conversion tracking problems can significantly affect campaign performance because optimisation decisions depend on the quality of conversion data. A campaign optimising toward an event that is not firing correctly, is firing on the wrong action, or is double-counting conversions will make decisions based on inaccurate data. Auditing conversion tracking before launching or scaling a campaign is one of the highest-priority technical checks in performance marketing.

Building a Performance Marketing Strategy

Setting Goals

Performance marketing strategy starts with clear, specific goals. A goal of “generate more leads” is not specific enough to build a campaign around. A goal of “generate 40 qualified leads per month at a CPL below $70 for the web design service” is specific enough to determine channel selection, budget allocation, and what success looks like.

Goals should connect directly to commercial outcomes: revenue, profit, customer acquisition, or specific conversion volumes. Impressions, reach, and followers can provide useful context, but they should not replace the conversion and commercial metrics used to evaluate an outcome-focused campaign.

Choosing the Right Channels

Channel selection follows the audience and the objective. For audiences actively searching for a product or service, paid search captures that demand. For audiences who are not yet searching but match the profile of a potential customer, social advertising builds awareness and retargeting maintains visibility. For businesses with an established content and SEO presence, performance marketing can complement organic acquisition by targeting additional audiences, supporting commercial campaigns, and providing another measurable acquisition channel alongside existing organic activity.

A performance marketing strategy may combine multiple channels when each has a clear role in the customer journey, rather than relying on a single channel for all outcomes.

How Performance Marketing Can Generate Leads and Sales

Performance marketing generates leads by driving targeted audiences to offers and landing pages designed to capture enquiry details in exchange for something of value, such as a consultation, guide, audit, or quote. It generates sales by placing products or offers in front of audiences with high purchase intent and minimising friction in the path from click to conversion.

The conversion rate from click to lead or sale is as important as traffic volume. A campaign driving high volumes of poorly qualified traffic may produce low CPC or even low CPL while still generating poor-quality leads and weak commercial results. A campaign driving smaller volumes of highly qualified traffic may have a higher CPC but generate better customers and stronger overall economics.

Campaign Optimisation: What It Actually Involves

Optimising a performance marketing campaign means making specific, data-supported changes to improve the commercial outcome. It is not a vague process of “tweaking” things. Specific optimisation activities include:

• Pausing keywords, audiences, or ad variations that are consuming budget without producing conversions.
• Allocating more budget to campaigns, ad sets, or keywords producing the best cost per acquisition.
• Testing different creative executions to improve click-through rate.
• Testing different landing page elements to improve conversion rate.
• Refining audience targeting based on which segments are converting at the lowest cost.
• Adjusting bids based on device, time of day, or geography where performance varies.

Each of these decisions should be driven by data rather than assumptions, and changes should be made methodically rather than simultaneously so their effect can be isolated.

Using First-Party Data in Performance Marketing

First-party data is information a business collects directly from its own customers and prospects: email lists, CRM records, purchase history, website behaviour, and form submissions. First-party data can be particularly valuable because it comes directly from a business’s own customers and prospects and can provide information that is specific to its products, audiences, and customer journey.

Practical uses of first-party data in performance marketing include uploading customer email lists to create matched audiences on Google and Meta, excluding existing customers from acquisition campaigns to avoid wasting budget on people who have already converted, using customer lists to create audience segments and support acquisition or remarketing campaigns where supported by the platform, and using purchase history to personalise retargeting messages based on what a customer has and has not bought.

As privacy requirements, browser restrictions, and platform measurement changes continue to evolve, first-party data can become increasingly important for audience understanding and measurement. Businesses that maintain clean, structured first-party data can be better positioned for audience understanding, measurement accuracy, and campaign optimisation.

Comparisons

Performance Marketing vs Digital Marketing

Digital marketing is the broader category that encompasses every form of marketing conducted through digital channels: SEO, content marketing, social media, email, paid advertising, and more. Performance marketing is a subset of digital marketing specifically focused on measurable, outcome-based advertising.

A business can engage in digital marketing without applying performance marketing principles, for example by running a social media presence and a blog without structured conversion tracking or measurable acquisition goals. A business doing performance marketing is a subset of digital marketing activity.

The two are complementary. SEO and content marketing build long-term organic visibility. SEO and content marketing can build organic visibility over time, while performance marketing provides another measurable acquisition channel that can operate alongside it.

Performance Marketing vs Brand Marketing

Brand marketing aims to build awareness, recognition, and emotional connection over time. It is harder to measure directly because its effects accumulate over months and years rather than hours and days. Performance marketing aims to produce specific, measurable actions within a defined timeframe.

The two approaches serve different objectives and are most effective when used in combination. Brand marketing can build recognition that influences how audiences respond to performance marketing campaigns. Brand familiarity can influence how people respond to paid ads, landing pages, and offers. Businesses with established recognition may see stronger conversion rates and lower acquisition costs in some contexts, though this varies by category, audience, and competitive environment.

Brand marketing and performance marketing can serve different roles within the same overall marketing strategy.

Performance Marketing vs SEO

SEO generates organic visibility in search results over time. Paid campaign delivery generally depends on continued budget. Paid advertising stops appearing when campaigns are paused or budget is exhausted, although conversions can continue to occur after an ad interaction due to conversion delays. The differences between them matter for how each is evaluated and when each is appropriate.

SEO requires sustained investment over months before producing meaningful organic traffic. Its returns can persist after publication, though organic visibility requires ongoing maintenance and can change with increased competition, search system updates, and content quality requirements. Paid campaign delivery generally depends on continued budget. Paid advertising stops appearing when campaigns are paused or budget is exhausted, although conversions can continue to occur after an ad interaction due to conversion delays.

SEO is not performance marketing in the strict sense because the cost model is not tied to specific conversions. However, the pages that generate organic traffic can be part of a performance marketing strategy when they are tracked and optimised for conversion outcomes.

Many Australian businesses use both approaches together, with performance marketing supporting immediate acquisition while SEO builds longer-term organic visibility. Both require ongoing management: paid campaigns depend on continued budget, while organic visibility requires continued effort to maintain and improve.

Is Performance Marketing Worth It?

Whether performance marketing is worth it for a specific business depends on three things: whether the numbers work, whether the business has the infrastructure to convert the traffic it generates, and whether the expectations are realistic.

When It Works

Performance marketing is more likely to perform well when there is clear search demand for the product or service (paid search), when the target audience has identifiable characteristics that allow precise targeting (social advertising), when conversion tracking is set up correctly so optimisation decisions are based on accurate data, when the landing pages or offer pages are designed to convert the traffic being sent, and when the business has a structured process for following up and converting the leads or sales generated.

When It Struggles

Performance marketing struggles when conversion tracking is missing or unreliable, when landing pages are not designed for conversion and traffic bounces without acting,when the campaign budget is too low relative to expected costs and conversion volume to generate enough useful data for meaningful optimisation, when expectations are set around vanity metrics rather than commercial outcomes, or when the product-market fit is weak and no amount of advertising will overcome fundamental commercial problems.

Is Performance Marketing Profitable?

Profitability depends on the relationship between the cost of acquiring a customer and the value of that customer to the business. A campaign producing a CPA of $200 for a business whose customer generates $2,000 in sustainable value has a very different economics from one where the customer generates only $150 in revenue. Whether the CPA is sustainable depends on margins, fulfilment costs, repeat purchases, and the other costs associated with acquiring and serving the customer. Whether a CPA is sustainable depends on the full margin picture, not revenue alone.

How Long Does Performance Marketing Take to Produce Results?

Paid search campaigns can generate clicks and traffic within hours of going live. However, the amount of useful optimisation data available during the early stages depends on factors such as budget, traffic, conversion volume, conversion-cycle length, and bid strategy. For Google Ads Smart Bidding, Google says the learning period is primarily affected by conversion volume, conversion-cycle length, and bid strategy. It can take up to around 50 conversion events or three conversion cycles for a bid strategy to calibrate to a new objective, although it may happen faster when sufficient conversion data already exists in the account.

A new campaign can produce early data quickly, but the amount of useful optimisation data available within the first weeks depends heavily on budget, traffic, conversion volume, and the length of the customer journey.

Performance Marketing Costs

What Budget Is Needed?

There is no universal minimum budget for performance marketing. The appropriate budget depends on the channel, expected cost per click or conversion, desired conversion volume, campaign objective, and the amount of data available for optimisation.

There is no universal starting budget for Google Ads. A practical budget depends on expected cost per click, conversion rate, target cost per acquisition, and the competitiveness of the market. A practical approach is to work backwards from commercial requirements: how many conversions are needed, what cost per conversion the business economics can sustain, what conversion rate is realistic for the offer and landing page, and what cost per click the market is likely to produce. This gives a budget range grounded in the business’s actual numbers rather than an arbitrary starting point. Highly competitive categories such as legal services, insurance, and financial advice have significantly higher costs per click, which affects the budget required to generate meaningful data.

Meta Ads budgets should be determined from the target cost per result, expected conversion volume, and campaign structure. A budget that is too small relative to the expected cost per conversion will produce insufficient data for meaningful optimisation, while a larger budget does not automatically make a campaign profitable.

These figures represent ad spend alone. Agency management fees are separate and vary significantly depending on the scope of work, the size of the campaigns, and the agency’s pricing model.

How Much Do Performance Marketing Services Cost?

Performance marketing agencies typically charge in one of three ways. A flat monthly retainer covering campaign management, optimisation, and reporting. A percentage of ad spend, where the agency fee is calculated relative to the campaign budget. A performance-based model where the agency earns a commission on results generated.

Performance marketing should not be confused with performance-based agency pricing. A performance marketing campaign can be managed under any commercial arrangement including a flat retainer, a percentage-of-spend model, or a commission structure.

Each pricing model has different implications. A flat retainer means the agency’s fee does not change with budget size, which can align effort with outcomes rather than spend. A percentage-of-spend model can create incentives to increase budget rather than improve efficiency, so it is worth discussing how optimisation decisions are made under this arrangement. A performance-based model creates alignment on results but can create complexity around attribution methodology and what counts as a billable outcome. No model is universally superior; the right arrangement depends on the scope of work, campaign scale, and how the relationship is structured.

What Does a Performance Marketing Agency Do?

A performance marketing agency manages the full process of campaign strategy, setup, execution, measurement, and optimisation on behalf of a client. Specifically, this includes channel selection and campaign strategy based on the client’s goals and audience, account setup and technical configuration (conversion tracking, pixel installation, audience setup), campaign creation (keyword research, audience building, ad creative, copy, and landing page recommendations), ongoing management and optimisation (budget allocation, bid adjustments, creative testing, negative keyword management), attribution and reporting (connecting campaign activity to commercial outcomes), and strategic recommendations based on performance data.

What to Look for in a Performance Marketing Agency

Certifications and platform partnerships can demonstrate platform knowledge, but they should be considered alongside evidence of relevant results, transparent methodology, reporting, and account management.

Useful indicators include:

• Evidence of results for comparable businesses, with enough context to assess relevance.
• Transparency about methodology, reporting frequency, and how decisions are made.
• Clear explanation of how success is measured and what constitutes a good outcome for the specific business.
• Willingness to discuss attribution honestly, including its limitations.
• Clear account ownership so the business knows who manages the account day-to-day.
• Reporting that connects campaign activity to commercial outcomes rather than only platform metrics.

Questions worth asking before engaging: What does your reporting cover and how often do we meet to discuss it? What attribution model do you use and why? What would cause you to recommend pausing a campaign? How do you handle the learning phase for new campaigns? Can you show examples of campaigns you have run for businesses similar to mine?

When Should a Business Hire a Performance Marketing Agency?

Hiring an agency makes sense when the cost of the mistakes made by learning in-house exceeds the cost of professional management, when the campaign scale is large enough that dedicated expertise produces meaningfully better results, when the business lacks the internal capacity to manage campaigns consistently, or when previous in-house attempts have produced campaigns that spend but do not convert.

It does not make sense when the business has no clear conversion tracking in place (an agency cannot optimise what cannot be measured), when the budget is too small to support both ad spend and management fees at viable levels, or when the business itself cannot handle the enquiries or orders that a successful campaign would generate.
