Your conversion tracking is real when every conversion Google Ads counts is a purchase or a qualified lead, counted once, and close to what your shop or CRM recorded. If your return on ad spend looks too good to be true, check first whether GA4 and Google's own tag are both counting the same sale. That one setting can double the number on your dashboard.
How we set up and read search accounts is on our Google Ads page. Below is the check you can run yourself.
Why tracking matters more than the ads
The algorithm only does what it is told. Smart bidding learns from the conversions you feed it, so the conversions decide who it goes looking for.
Feed it page views and it finds browsers. Feed it a sale counted twice and it puts more money behind campaigns that only look like winners. That is why, before we touch a campaign, we check the foundations.
The six-step check
1. List what counts as a conversion
Open the conversion actions in Google Ads and write down every one marked as primary.
Keep: purchases, qualified leads, booked calls. Actions that make the business money.
Question: page views, time on site and other top-of-funnel vanity metrics. These belong in reporting, not in what the bidding chases.
2. Look for the same sale counted twice
This is the first thing to rule out when results look unusually strong.
Is GA4 importing transactions into Google Ads?
Is the native Google Ads conversion tag also recording purchases?
Are both set as primary?
If the answer to all three is yes, the same sale can be counted twice, and your reported return on ad spend artificially doubled.
3. Compare the platform with your backend
Pick a recent period. Put the conversions Google Ads reports next to the orders in Shopify, or the leads in your CRM.
They will rarely match exactly. A gap that keeps growing in Google's favour is the one to chase.
While you are in your backend, check that your pixels are firing on every page that matters, including the confirmation page.
4. Check the checkout
Tracking is also how you see what you lose. How many people start checkout and do not finish? If that number is unknown, part of your wasted spend is invisible. We look at every touch point, because a leak at checkout costs as much as a bad keyword.
5. Check Meta's signal too
If you run Meta alongside Google, check whether the Meta Pixel receives server-side data through the Conversions API. Without it, an account can be losing 30% of its signal to iOS privacy restrictions, and Meta's delivery has less to learn from.
6. Set a baseline before you fix anything
Write down today's numbers: conversions, cost per conversion, return on ad spend, and your real orders or leads. When you fix duplicated or wrong conversions, reported results may drop. A baseline shows that the account got more honest, not worse.
What to do if your tracking fails the check
Fix tracking before budgets. Moving money on bad data just moves the problem.
Change one thing at a time. In a first audit we make no budget change over 15 to 20%, and leave the best-performing campaigns alone until the data is clean.
Read the business numbers. Order value and lifetime value tell you more than any platform metric.
For the other places budget goes missing, see where Google Ads budget leaks. For the full order we work in, read how to audit a Google Ads account in ten minutes.
How we handle it
Tracking is part of the foundations on every retainer. The first 15 days cover access, audits, tracking and baselines. After that, a dashboard shows week on week whether we are hitting the goals in the plan, measured against real sales.
FAQ
What is conversion tracking in Google Ads?
It is how Google Ads records the actions that matter to your business, such as a purchase or a lead. Smart bidding uses those records to decide who to show your ads to.
Why is my Google Ads return on ad spend higher than my real sales?
Often because the same sale is counted twice, once by GA4 and once by the Google Ads tag. Compare the platform with your shop or CRM for the same period.
Should page views count as conversions?
Not as primary conversions. If they do, the bidding will chase people who browse rather than people who buy.
Do I need the Meta Conversions API?
If you run Meta ads to drive sales, check it. Without server-side data, an account can be losing 30% of its signal to iOS privacy restrictions.
