How Do I Know If My Marketing Is Working?

Start with the job marketing was supposed to do

Before reviewing the numbers, define the campaign's purpose.

Marketing might be intended to:

• generate immediate sales;
• create qualified quote requests;
• fill unused capacity;
• introduce a new service;
• encourage repeat purchases;
• build trust before a seasonal buying period.

Those are different jobs. A local service ad meant to generate calls this month should not be judged like an educational video designed to build trust over several months. A retention email should not be measured like a campaign targeting new buyers. Marketing becomes difficult to evaluate when the business never defines what success was supposed to look like.

Follow the full path to contribution

A useful marketing review follows the complete customer path:

• Attention
• Inquiry
• Qualified opportunity
• Quote, proposal, visit, or sales conversation
• Customer won
• Work completed or product delivered
• Cash collected
• Contribution earned

Each stage answers a different question. Attention shows whether people noticed the message. Inquiries show whether some responded. Qualified opportunities show whether the right people responded. Sales results show whether the business converted them. Collected revenue and contribution show whether the result was economically worthwhile. If the business stops at clicks or inquiries, it cannot tell whether marketing created customers or simply created more work.

Find the first stage where performance weakens

This guide owns the full-path diagnosis. The deeper guides explain how to correct individual stages.

Measure contribution, not just revenue

Collected revenue means money the customer has actually paid, not merely work that was quoted, booked, completed, or invoiced.

Start with:

Marketing contribution = collected revenue from marketing-generated customers - direct job or product costs - marketing cost - commissions - channel-specific sales costs

Where material, also subtract:

• discounts;
• returns;
• rework;
• collection costs;
• unusual delivery or service expense.

Suppose a business spends $4,000 on a campaign and wins six customers. The results are: Collected revenue: $30,000. Direct labor and materials: $17,000. Marketing cost: $4,000. Sales commissions and campaign-specific estimating: $2,000. Rework and collection costs: $1,000. Marketing contribution: $30,000 - $17,000 - $4,000 - $2,000 - $1,000 = $6,000. Contribution return on marketing spend: $6,000 / $4,000 = 1.5. The campaign produced $1.50 of contribution for each marketing dollar after the included costs. This is not raw return on ad spend, or ROAS. An ad platform may divide revenue by ad spend and show a much larger number. This calculation asks what remained after the major customer and campaign costs.

Do not count revenue that has not been collected

Suppose the same campaign generated $35,000 of invoices, but only $30,000 has been collected and $5,000 remains outstanding.

The marketing review should begin with the $30,000 actually received unless there is strong reason to treat the remaining receivable as nearly certain.

If the $5,000 later becomes bad debt, counting the full invoiced amount would overstate the campaign's result and could encourage the business to spend more based on money it never received.

Cash timing also matters. A campaign can appear profitable while creating pressure if marketing, labor, materials, or fulfillment must be paid long before the customer pays.

Match the review period to the buying cycle

Do not judge every campaign over the same amount of time.

A retail promotion may produce results within days. A seasonal service campaign may need several weeks. Commercial projects, consulting work, or high-value purchases may take months from first contact to collected cash.

Stopping too early can make a useful campaign look weak. Waiting indefinitely can protect a bad campaign from accountability.

Before launch, define:

• the evaluation period;
• the normal buying cycle;
• the minimum number of meaningful opportunities;
• the maximum test loss;
• the conditions that trigger improvement, limitation, or stopping.

Track customers by the period in which they first entered the process so later sales and collections remain connected to the original campaign.

Include sales effort

Two campaigns can produce similar contribution while consuming very different amounts of owner or employee time.

Suppose:

• Campaign A creates $8,000 of contribution and requires 60 sales hours.
• Campaign B creates $7,000 of contribution and requires 15 sales hours.

Contribution per sales hour: Campaign A: $8,000 / 60 = about $133 per hour. Campaign B: $7,000 / 15 = about $467 per hour. Campaign A creates more total contribution. Campaign B uses scarce sales capacity more efficiently. Use the result this way: Increase when contribution per sales hour is healthy and more sales capacity is available. Improve when the campaign produces good customers but requires too much explanation, estimating, or follow-up. Limit when the campaign is profitable but the owner or sales team is already at capacity. Stop when the sales effort repeatedly consumes more value than the resulting contribution justifies. Sales time is not free, especially when the owner, estimator, or salesperson is already the bottleneck.

Check customer quality and capacity

Marketing is not working well if the customers it produces repeatedly:

• reject normal pricing;
• fall outside the service area or delivery model;
• buy work the business does not want;
• pay slowly;
• require unusual support;
• create excessive rework;
• strain available capacity.

Use Which Marketing Channels Bring Better Customers? when comparing the quality and economics produced by different sources. If a profitable campaign creates delays, rushed work, or owner overload, the decision may be to limit demand rather than increase spending.

Use one decision framework

For each campaign or major channel, record:

• objective;
• amount spent;
• inquiries;
• qualified opportunities;
• customers won;
• collected revenue;
• direct costs;
• contribution;
• sales hours;
• payment or service problems;
• repeat or referral activity;
• capacity effects.

Frequently asked questions

Run a first marketing review

Choose one campaign or channel and identify:

• the job marketing was supposed to do;
• the first stage where the path weakens;
• the contribution from collected revenue;
• whether enough time has passed for the buying cycle;
• the sales effort and capacity required;
• the one change to test next;
• whether the right decision is Increase, Improve, Limit, or Stop.

A downloadable Marketing Performance Scorecard is planned as a companion to this guide. Until it is built and approved, the review above remains usable on its own. Marketing is not working merely because activity increased. It is working when the business wins suitable customers at acceptable economics without creating a larger problem elsewhere.
