Tested, Not Installed
Every action triggered manually and checked in the account before anything relies on it.
Automated bidding pursues whatever you report as success. If that is the wrong event, counted twice, or missing the phone calls entirely, the account optimises confidently in the wrong direction. Google Ads conversion tracking is therefore the first thing to get right and the most common thing to find broken.
A conversion action existing in the interface is not evidence that it fires, fires once, or fires on the right thing.
Every action triggered manually and checked in the account before anything relies on it.
For most service businesses, calls are the majority of conversions and the most commonly missing one.
A tag firing on both a thank-you page and a form event doubles every number in the account.
A conversion worth £50 and one worth £5,000 counted identically means the bidding cannot tell them apart.
Where a CRM knows which leads were real, that belongs back in the account — see B2B PPC.
Four failures, in roughly descending order of how often they turn up.
Check My Tracking →The account counts forms, the business receives calls, and the campaigns are judged on a fraction of their results.
The same conversion recorded by two mechanisms, so every reported figure is inflated.
A page view counted as a lead, or a newsletter signup counted the same as a sales enquiry.
Every conversion worth the same to the bidding, regardless of what it was actually worth.
Audit what exists, fix what is wrong, and verify everything before the account is judged on it.
Once tracking is right, account optimisation has something reliable to work from.
Verification is most of the work. Installing a tag takes minutes; proving it is correct takes longer and matters more.
Every conversion action in the account, what it claims to measure, and when it last fired.
Each one triggered manually and confirmed in the account, including on mobile.
Duplicates removed, missing actions added, values assigned.
Where a CRM holds the outcome, it gets imported back.
What each action means and who owns it, written down.
Smart Bidding is not making judgements about lead quality. It is finding more of the event you defined, as cheaply as it can.
The closest event to revenue that you can measure reliably. For ecommerce that is the purchase with its value. For a service business it is usually a qualified enquiry rather than any form submission.
The temptation is to count everything, because more conversions makes the account look better. It also makes the bidding worse: an account counting newsletter signups alongside sales enquiries will find more newsletter signups, because they are easier.
Where a softer event has to be used because volume is too low, it should be given a lower value rather than an equal one.
Most often when a conversion is tracked twice by different mechanisms — a tag on the thank-you page and an event on the form submission, or a Google Ads tag and a Google Analytics goal both imported.
The symptom is an account that reports more conversions than the business received, and a cost per conversion that looks better than reality. It is easy to miss because nothing errors; the numbers are simply wrong.
Finding it means reconciling the account against what the business actually recorded, which is why the audit starts with that comparison rather than with the tags.







Google Ads conversion tracking records what happened after a click — a form, a call, a purchase — so the account can report performance and automated bidding can optimise toward it.
Because a phone call leaves no page view to record. Without call tracking the account sees only the enquiries that arrived by form, which for most service businesses is the minority — and it will optimise against a partial picture.
Where the business can supply one, yes. Without values, bidding treats a small enquiry and a large one as equivalent and pursues whichever is cheaper to obtain, which is usually the small one.
Sending outcomes from your CRM back to Google Ads against the original click — so the account learns which clicks produced leads sales actually accepted, rather than which produced form submissions.
By testing each action deliberately and reconciling the account against what the business recorded over the same period. If the two disagree, the account is wrong — and it is wrong more often than most advertisers expect.
Still deciding if google ads conversion tracking is right for you?
Talk to UsConversion tracking is treated as setup — done once, at the start, by whoever built the account, and never revisited.
It is also the input to every automated decision the account makes afterwards. Bid adjustments, budget allocation, audience expansion and campaign pausing all follow from what was reported as a conversion. If that input is wrong, every downstream decision is confidently wrong.
It is the least interesting part of paid search and the one where an hour of checking most often changes what the account does for the following year.
Give us read-only access. We will test each conversion action, check for double counting, and reconcile what the account reports against what you actually received.
