Your campaign is running. Ads are being displayed, people are clicking, and your budget is being spent. The problem is that there are few or no sales or enquiries.
The first reaction is often to change the campaign, adjust keywords, or increase the budget.
But the problem is not always Google Ads.
A bigger budget will not fix a form that fails to send enquiries. Better ads will not help if users land on the wrong page. Bid optimisation will not solve a checkout that does not work properly on mobile devices.
Before rebuilding the campaign, it is worth checking the entire journey:
ad → landing page → offer → form or shopping cart → payment → conversion tracking.
The problem can occur at any point in this journey.
1. First, check whether there really are no sales
Start with the most basic question: is the campaign actually failing to generate sales or leads, or are those conversions simply not visible in Google Ads?
Compare data from several sources:
- Google Ads,
- your ecommerce platform,
- your CRM,
- contact forms,
- your payment system,
- web analytics.
If your store shows 20 orders while Google Ads reports only two conversions, the problem may be conversion tracking rather than sales performance.
The opposite can also happen. Google Ads may report a large number of conversions, but a closer look reveals that some of them are simply phone number clicks, form opens, or visits to a particular page.
In that case, the campaign may look successful in the dashboard without necessarily delivering meaningful business results.
Google explains that conversion values can be used to represent how valuable different actions are to a business. This means it is important not only to track a conversion, but also to understand what that conversion actually represents.

2. Complete one test conversion from beginning to end
Instead of starting with dozens of reports, perform one controlled test.
Visit the website through a properly tagged link or ad and follow exactly the same journey that a potential customer would.
If the campaign is designed to generate ecommerce sales:
- open the landing page,
- find the product,
- add it to the cart,
- go through checkout,
- place a test order,
- check whether the order appears in your system,
- check whether the conversion is recorded correctly.
For lead generation campaigns, follow the same principle and trace the enquiry all the way to the CRM or inbox where it should eventually appear.
The goal is not to generate random leads in production. The test should be controlled and clearly marked so that the sales or customer service team knows it is a test.
This simple exercise can reveal problems that are difficult to identify in advertising reports alone.
3. Check what kind of clicks you are actually paying for
If conversion tracking works correctly, the next step is to look at traffic quality.
A click does not automatically mean purchase intent.
Imagine that a company sells paid ecommerce implementation services, but its ads attract people looking for:
- a free ecommerce template,
- a tutorial for setting up a store themselves,
- ecommerce developer jobs,
- a free tool,
- educational resources.
The traffic may be related to the general topic, but the user's intent is completely different.
Review search terms, ad groups, products, and other available information about where your traffic comes from and what users are looking for.
The question should not only be:
Are people clicking?
More importantly, ask:
Are the people clicking actually interested in buying what we offer?
4. Check whether the ad and landing page make the same promise
After clicking an ad, users should quickly recognise the offer that attracted their attention.
If an ad promotes:
Ecommerce accessibility audit.
but sends users to the homepage of a company offering a dozen different services, they have to find the relevant offer themselves.
Every additional step creates another opportunity for the user to leave.
Check the consistency between:
- the ad headline and the landing page headline,
- the advertised product and the product shown on the page,
- prices and offer conditions,
- calls to action,
- promotional information,
- what the user expects and what they actually see after clicking.
The wording does not need to be identical. The important thing is that users immediately understand that they have arrived in the right place.
5. Check whether you are asking for too much too soon
Sometimes the ad and offer are good, but the problem appears when the user tries to make contact.
Imagine an ad promoting a consultation for a software implementation. The user clicks “Let's talk” and is immediately presented with a form containing numerous required fields about budget, technology, deadlines, features, and project specifications.
That is a lot of work for someone who is only considering making initial contact.
In this situation, it may be worth testing whether a shorter form generates more valuable enquiries.
You can start by collecting a few essential details and gather the rest during the conversation.
However, do not evaluate the change based only on the number of submitted forms. More leads do not necessarily mean better results if their quality decreases significantly.
6. Go through the entire process on a mobile phone
Do not assume that because a form or store works correctly on a desktop computer, it also works correctly on mobile.
Use a real phone and complete the same journey.
Check:
- how quickly the page loads,
- whether the most important information is easy to find,
- whether buttons are easy to tap,
- whether the form can be completed without problems,
- whether the on-screen keyboard covers important elements,
- whether delivery and payment options can be selected,
- whether error messages are visible,
- whether a clear confirmation appears after submitting the form.
A problem affecting only mobile users can be difficult to notice if you look only at the campaign's overall average performance.
It sounds obvious, but this is one of the problems worth ruling out early.
A user may successfully complete a form and see a “Thank you for your message” confirmation while the enquiry never actually reaches the sales team.
Possible causes include:
- an application error,
- an SMTP server problem,
- messages being blocked by spam filters,
- an incorrect CRM integration,
- an outdated recipient address,
- a broken webhook or third-party integration.
This is why the test should not end when the user sees a confirmation message. It should end when the enquiry actually reaches the place where your company receives and processes it.
8. For ecommerce, check the cart, checkout, and payments
If Google Ads sends users to an online store, the problem may occur much later than the landing page.
A customer may be interested in a product and add it to the cart, only to encounter a problem with delivery selection, a discount code, the address form, or payment.
Test the entire process:
product → cart → customer details → delivery → payment → confirmation.
Pay attention to third-party integrations as well. A broken delivery provider widget or a problem after redirecting to a payment provider can reduce sales even when the advertising campaign itself is working correctly.
9. Check whether technical errors appeared at the same time
If the campaign previously generated sales and performance suddenly dropped, compare the timing of that decline with what was happening on the website.
Check for:
- application errors,
- HTTP 500 responses and other server errors,
- API problems,
- slow response times,
- database problems,
- JavaScript errors,
- deployments made during that period,
- changes to forms, checkout, or integrations.
If the drop in conversions started immediately after a new checkout version was deployed, that is a much more useful clue than simply concluding that “Google Ads stopped working”.
Application error and availability monitoring can be just as useful here as advertising reports.
10. Check what happens after a lead is submitted
The customer journey does not always end with a form submission.
If you sell a service that requires contact with a salesperson, check what happens next.
The form may work perfectly and the campaign may generate relevant enquiries, but potential customers might not receive a response for three days.
Or the enquiry may be sent to an inbox that nobody checks regularly.
In this situation, Google Ads may be doing its part correctly while the actual problem occurs later in the sales process.
Don't change everything at once
When a campaign is not producing the expected results, it is easy to fall into the trap of changing everything at the same time.
Ads, keywords, landing pages, forms, offers, and budgets are all changed simultaneously.
If performance improves afterwards, it becomes difficult to determine what actually caused the improvement.
Instead, divide your findings into three groups:
- confirmed problems – you know something is not working,
- strong hypotheses – the data suggests a potential problem,
- missing data – additional tracking or testing is required.
Start by fixing confirmed issues that block sales or make your measurement unreliable.
Then test the remaining hypotheses one at a time.
Where should you start when Google Ads gets clicks but no sales?
A practical diagnostic order looks like this:
- Tracking – are sales and leads being recorded correctly?
- Traffic – are your ads attracting users with the right intent?
- Landing page – does it match the promise made in the ad?
- Offer – does the user understand what they will get and why it is valuable?
- Process – do the form, shopping cart, and checkout actually work?
- Technology – are errors or performance issues blocking some users?
- Follow-up – do leads and orders reach the right place and receive appropriate attention?
Only after checking this entire journey can you make a better-informed decision about whether the campaign itself needs to be changed.
At Dock, we look at Google Ads as one part of the complete customer acquisition process. We can analyse the campaign, conversion tracking, and user journey, and if the problem is caused by the website, form, ecommerce process, or an integration, we can also implement the necessary changes.
If your ads generate traffic but not business, start by finding the point where potential customers drop out.
