How do you know whether paid advertising brings customers?

9 min readUpdated 6.10.2026alma studio

To find out whether paid advertising brings customers, connect enquiries attributed to advertising with their outcomes in your business. Open the campaign report alongside your enquiry records to establish what was counted, which requests suited the service and which became sales. We recommend completing this picture before increasing the budget or replacing a campaign, rather than relying on activity alone.

What your report actually counts

A conversion is an action selected for measurement. It does not necessarily mean someone became a customer. Google's documentation on enquiry stages and Microsoft's separate documentation on offline conversions distinguish initial contact from subsequent progress. For your business review, give each stage a name that describes what actually happened.

If your tracking counts a click on a WhatsApp button, call it a WhatsApp click rather than an enquiry received until you confirm there is a message or conversation to handle. If a form submission is counted, check that your team receives it. We recommend making a test enquiry and following its route before relying on that report line.

Nor does a count of actions necessarily represent a count of people. Counting settings can include repeated actions or limit them according to defined rules, as Google and Microsoft explain. Do not automatically add forms and calls together and label the total new customers. For the enquiry register proposed here, we suggest keeping repeat contacts from the same person about the same request under one enquiry.

Define a suitable enquiry before reviewing the totals

The label quality lead says too little about what needs improving. Write down what must be true for you to serve the person making contact, starting with the service and your service area. Add conditions that genuinely affect suitability, such as availability on the requested date.

As a hypothetical example, a business working only within Eilat would not accept a request elsewhere. For a business serving the whole country, location alone should not disqualify an enquiry. Let the definition reflect your business, not the report reader's assumptions.

Someone who has not answered stays awaiting clarification until there is enough information. We suggest this separation even when it would be easier to mark every uncompleted enquiry unsuitable. A person who declines a relevant proposal requires a different investigation from someone requesting an unavailable service. Record the reason you know without inventing one.

An enquiry register you can maintain during the working day

Start with a spreadsheet maintained by whoever handles enquiries. Decide who records outcomes and when before buying a system. If your business already has one, add the missing fields instead of starting another register. The table offers a starting point to adapt.

What to recordWhat it helps you establish
Enquiry ID and date receivedWhich group of enquiries to revisit
Known source or unknown sourceWhat can be attributed to advertising and what cannot
Requested serviceWhether the request matches the advertised service
Suitable, unsuitable or awaiting clarificationWhether there is enough information to assess fit
Last action and next stepWhether the business or the prospective customer needs to act
Paid sale, not proceeding or still openWhich outcomes are known and which remain unresolved

Keep the register for the people handling enquiries and share the information needed for discussion in the summary. Leave an unknown source unknown rather than attributing it to the campaign by intuition. Record cancellations or refunds against paid sales so the outcome stays current.

Cost per enquiry and cost per customer answer different questions

The basic cost per action calculation is spending divided by the number of measured actions. Both Google and Microsoft define it this way. Your business question is which actions belong in the calculation.

For this review, divide spending by enquiries received and then by suitable enquiries. Once outcomes are known, calculate spending per paid sale from that group. Count new customers separately when calculating cost per new customer: several sales to one customer are not several customers. If the assessed stage has no outcomes, do not report a cost of zero; there is nothing to divide the spending by.

Use the same spending definition and an enquiry group connected to it. Do not compare ads alone with a calculation including management and website work. Where the connection is incomplete, label the result an estimate. This review assesses the cost of reaching an outcome, not business profit on its own.

An example where more enquiries do not mean more sales

These numbers are invented for explanation, not client results. Suppose two campaigns for the same service spend equally over comparable periods and count distinct enquiries rather than button clicks. All follow-up is complete, with no pending sales or unrecorded cancellations.

Outcome assessedCampaign ACampaign B
Enquiries received6030
Suitable enquiries1218
Paid sales36

With equal spending, campaign A has a lower cost per enquiry because it receives twice as many enquiries. Campaign B has a lower cost per paid sale because it produces twice as many paid sales. The same budget comparison gives a different answer depending on the stage assessed.

To decide whether campaign B is more profitable, check transaction values and service delivery costs too. The table gives you a reason to investigate why campaign A attracted more unsuitable requests and fewer suitable enquiries progressed. That is more specific than asking for more leads.

Allow time for enquiries to reach an outcome

There can be a delay between an ad click and the action recorded afterwards. Google describes this delay in conversion reporting and Microsoft defines a reporting metric for it. For your business review, also track the time between receiving an enquiry and completing the follow-up.

Imagine an Eilat business receiving a quote request near month end for work planned later. Keep the enquiry open while the discussion continues, without counting a sale or treating the month ending as a failure. Revisit it at the next review.

We suggest keeping two views: enquiries received during the period with their known outcomes today, and sales paid during that period including those from earlier enquiries. Do not combine them without explanation because recent spending and older enquiries may not describe the same group of work.

Where to look when activity is not becoming sales

When there are clicks but few enquiries received, open the ad's destination page on a phone and look for the advertised service. Send a test enquiry and check that it arrives. Keep reading beyond a working form if the offer remains unclear.

Matching what a link suggests with what people find afterwards is a usability principle described by Nielsen Norman Group and, for advertising, by Google. We recommend checking that the page presents the same service and conditions. Our guide to a landing page or a full website examines the choice of destination without assuming a new website is necessary.

If enquiries do not fit, compare what people requested with the ad and page. Check for an unclear service area or an unavailable service being suggested. When suitable enquiries do not progress, read the follow-up record and replies to check availability and whether the proposal answered the request. These are investigations, not diagnoses established by one number.

When the page review identifies a structural problem, our website development service connects to the campaign work. If the issue concerns loading or responding on a phone, the website speed guide explains what to check before attributing every missing enquiry to speed.

Attribution does not prove advertising created every sale

A report can attribute a sale to advertising according to measurement rules. That is different from asking how many sales would not have happened without the campaign. The distinction appears in Google's conversion lift documentation and in original research published through Northwestern University. That study examined Facebook advertising, not outcomes for an Eilat business.

For routine reviews, distinguish new from returning customers and record what is known about their source. This helps examine observed outcomes and missing information without presenting the register as an experiment proving additional sales caused by advertising.

What to bring to the next campaign discussion

Ask for a report separating measured actions from enquiries received and known sales, with open enquiries and missing attribution identified. We would complete an outdated register before discussing a larger budget rather than base the decision solely on reported activity.

Choose one issue and record the action to investigate, its owner and the next review date. An unclear offer may require page work; unanswered enquiries need follow-up first. Our paid campaign management service connects advertising work to business information. For different audiences within the city, read our guide to planning paid advertising in Eilat.

At the next discussion, open several enquiries without an outcome and ask the person handling them to complete what is known so you can decide which to follow up.

This is exactly what we do at paid campaign management. If you want us to go over it together for your business, write to us.

Frequently asked questions

What is the difference between a conversion and a suitable enquiry?

A conversion is an action selected for measurement. A suitable enquiry has been received and assessed against the business's service conditions. In this review we also separate suitable enquiries from paid sales so an early stage is not credited with an outcome that has not happened.

What is a good cost per enquiry for paid advertising?

We do not suggest one threshold for every business. Check what happens to enquiries and the cost of reaching a paying customer within a group connected to the spending. Before deciding on a larger budget, also assess transaction values and the associated costs.

Can I start without buying a system?

For this review, use an existing register and add a follow-up status and known source to each enquiry. Decide who will update it first. A new system is not our default recommendation when the basic records are still missing.

How long should I wait before deciding whether a campaign works?

Schedule the review around the time your business takes to follow up and reach an outcome. Examine recent enquiries alongside older groups whose outcomes are known. Do not judge the campaign solely from a register full of open discussions, and do not postpone fixing a clear form fault.

How do I review enquiries from both ads and organic search?

Record the source when it is known and separate channels as far as the evidence allows. If a person's source is unclear, leave it unknown. Do not credit the same sale to every channel and add the figures as though several sales occurred.
