Short answer: when ads bring clicks but few enquiries, the cause is rarely "ads don't work." Money usually leaks at one of five points: you aren't measuring the right result, your ads show for the wrong searches, the page doesn't match the promise, the page is slow on a phone, or enquiries wait too long for a reply. Each can be checked in well under an hour.
This is for a business that is already paying for ads. If you're still deciding how much to spend, start with our post on setting a marketing budget.
Leak 1: You aren't measuring the result that matters
If your ad account counts clicks but not enquiries, it can't tell which ads, keywords or campaigns are producing them, and neither can you.
Google describes a conversion action as "a specific customer activity that is valuable to your business," and gives purchases, sign-ups and phone calls as examples. It says tracking them helps you learn "which keywords, ads, ad groups, and campaigns are best at driving valuable customer activity." Google also notes that misconfigured conversion actions "can prevent Smart Bidding from optimizing effectively," meaning its automated bidding can end up optimising toward the wrong thing.
Check it:
- Is a form submission or booking counted as a conversion? Submit a test enquiry and confirm it appears.
- Do calls count? Google lists calls from ads, calls to a number on your website and clicks on a phone number on a mobile site as measurable.
- Is anything counted as a conversion that isn't valuable, such as a page view? Remove it.
Fix first: if the answer to the first question is no, stop adjusting everything else. You are optimising blind. Our guide to five numbers that show whether your marketing is working covers what to count.
Leak 2: Your ads show for the wrong searches
Google's search terms report shows "the searches that trigger your ads and how those searches are performing." Many small accounts have never opened it.
Google's guidance is that if a search term "isn't relevant enough to the products or services you offer," you can add it as a negative keyword to "prevent your ad from showing to people who are looking for something you don't sell." Its example: an optometrist selling eyeglasses might add "wine glasses" as a negative.
Check it:
- Open the search terms report for the last 30 days and sort by spend.
- Mark each paid search as relevant, borderline or wrong.
- Add the wrong ones as negatives. Google notes negatives "won't match to close variants or other expansions," so you may need several forms of a term.
Other ad platforms have their own placement and audience reports. The principle is the same: look at what you actually paid to reach. If you're weighing channels, see Paid Search or Paid Social: Which One Fits Your Goal?.
Leak 3: The page doesn't match the promise
An ad promises one thing; the page it lands on leads with something else. The visitor has to work out whether they're in the right place, and many won't.
This is a practical judgement rather than something a platform will score for you. Open your ad, click it on your phone and ask:
- Does the headline on the page repeat the promise in the ad?
- Is the next step obvious without scrolling: call, book or enquire?
- Is there one clear action, or six?
- Does the page answer the question the searcher typed?
If you send every ad to your home page, this is the first thing to fix. A page built for one offer and one action will usually do more than a general page that has to serve every visitor.

Leak 4: The page is slow on a phone
Visitors from ads arrive on a phone more often than many owners expect, and a slow page loses them before they see the offer.
Google's web.dev defines three "good" thresholds for Core Web Vitals: Largest Contentful Paint within 2.5 seconds of the page starting to load, Interaction to Next Paint of 200 milliseconds or less, and Cumulative Layout Shift of 0.1 or less. It recommends assessing them at the 75th percentile of page loads, "segmented across mobile and desktop devices."
Check it:
- Run your landing page through Google's PageSpeed Insights and read the mobile result first.
- Look at the three measures above and note which are outside the thresholds.
- Ask whoever manages the site to fix the slowest element first, usually oversized images or heavy scripts. Your Website Is Slow: What to Fix First gives the order.
We aren't claiming a specific revenue gain from a faster page. The point is simpler: you are paying for every click, and a page that fails to load promptly wastes some of them.
Leak 5: Enquiries wait too long for a reply
Everything above can work and money still leaks if the enquiry sits unanswered.
A 2011 Harvard Business Review study by Oldroyd, McElheran and Elkington, "The Short Life of Online Sales Leads," concluded: "Our research shows that most companies are not responding nearly fast enough." The study is more than a decade old and was about sales leads in general, so treat it as direction rather than a benchmark for your business.
Check it:
- Send yourself a test enquiry from your ad landing page at an ordinary time of day and note how long a human takes to answer.
- Check where the enquiry actually goes. A form that emails an inbox nobody watches is a common leak.
- Set a target you can keep, such as replying the same working day, and write down who owns it.
A one-hour audit
| Leak | Where to look | Time | Fix first if... |
|---|---|---|---|
| 1. Measurement | Conversion actions in the ad account; a test enquiry | 15 min | Enquiries don't register as conversions |
| 2. Search terms | Search terms report, last 30 days | 15 min | More than a few paid searches are plainly irrelevant |
| 3. Page match | Click your own ad on a phone | 10 min | The page headline doesn't repeat the ad's promise |
| 4. Speed | PageSpeed Insights, mobile | 10 min | A Core Web Vitals measure is outside the "good" range |
| 5. Follow-up | Test enquiry, then time the reply | 10 min | Replies take longer than a day |
Work through them in this order. Leak 1 comes first because without it you can't judge whether anything else you change made a difference.
What this won't tell you
An audit finds leaks; it doesn't guarantee what plugging them is worth. Results depend on your market, offer, price and how many people were already ready to buy. If the offer itself is weak, a perfectly tuned funnel won't rescue it. And some fixes, such as site speed or tracking changes, need a developer or an agency.
Common questions
How many clicks do I need before judging an ad?
There's no single number. Judge by enquiries and cost per enquiry rather than clicks, and give a change enough time to collect meaningful data. Small accounts take longer to show a pattern.
Is it worth tracking phone calls?
Google lists calls from ads, calls to a number on your website and taps on a mobile number as measurable conversions. If many of your customers phone, ignoring calls hides a large part of the result.
Should I turn ads off while I fix these?
Not necessarily. Fix tracking first so you have a baseline. If you find spend going to clearly irrelevant searches, pausing those is sensible straight away.
Who should own follow-up?
One named person with a time target. Shared inboxes without an owner are where enquiries get lost.
