Google Ads Conversion Tracking Checklist

Google Ads conversion tracking decides what your campaigns learn. If the account counts the wrong action, automated bidding optimises for the wrong people, and your reports look better than your sales. When an account gets clicks but no sales, check measurement before blaming the traffic: measurement errors can make reported results misleading.

This checklist explains how to choose the actions you track, how to set up the Google tag, how consent mode fits in and how to check that every conversion is real before you change bids or budgets.

What is Google Ads conversion tracking?

Google Ads conversion tracking records the valuable actions people take after interacting with your ads, such as a purchase, a form submission or a phone call, and connects each action to the campaign, ad group and keyword that brought the visitor. According to Google Ads Help, this data is used both in reports and in Smart Bidding strategies such as Maximize Conversions and target CPA.

Solya Agency: a remote digital growth agency that sets up and audits Google Ads conversion tracking as part of its Google Ads consulting and conversion tracking and analytics services. Every conversion action is checked against real leads before it is used for bidding.

Step one: choose what counts as a conversion

Before any code goes on the site, decide which actions really matter to the business. A useful split is primary and secondary actions:

• Primary actions: completed purchases, successful form submissions, booked appointments or qualified calls. These are the actions bidding should learn from.
• Secondary actions: clicks on a WhatsApp button, clicks on a phone number, newsletter sign-ups or important page views. They show intent, but they are not results.
• Actions to avoid as primary: page views of the contact page, scroll depth or time on site. They are easy to collect and easy to inflate.

A click on a WhatsApp or call button is a common trap. The click shows interest, but it does not prove that a message was sent or a call was answered. Track it, but compare it with the conversations you actually receive.

Step two: install the Google tag correctly

Google's setup guide for web conversions starts with the Google tag. The essentials:

• One Google tag on every page, added through the site code or through Google Tag Manager, as described in Google's guide to setting up the Google tag.
• An event snippet only where the action is completed, for example on the thank-you page or on the success response of a form, not on the button click before validation.
• No duplicates: check that the tag is not installed twice, once in the theme and once through a plugin or Tag Manager. Duplicate conversion events can inflate reported conversions; check that each successful action sends the event once.
• Your own security headers: if the site uses a Content Security Policy, allow the Google domains the tag needs. Otherwise the browser can block the tag silently while the code still looks correct in the page source.

Step three: handle consent mode

If your site shows a cookie banner, consent mode passes each visitor's consent choice to Google tags, and the tags adjust their behaviour. Google offers a basic and an advanced implementation.

• Consent mode does not create the banner. It works with your existing banner or consent tool.
• Test both paths: accept all cookies once and decline once, then check what the tag sends in each case.
• Expect gaps: visitors who decline will not appear in your data the same way as visitors who accept. Do not read every drop in conversions as a campaign problem.

Step four: improve data quality

Once the basic tag works, a few additions make the data more useful:

• Enhanced conversions send hashed first-party data, such as an email address from a form, to improve conversion matching.
• Offline conversions let you import sales or qualified leads that close later, by phone or in person, using the Google Click ID.
• Conversion values: if different leads are worth different amounts, give them different values instead of counting every action the same.

Step five: check that conversions are real

Before you trust the numbers, compare them with actual business enquiries:

1. Use Tag Assistant to confirm that the conversion event fires once after a successful action. A verified tag does not mean the conversion appears in campaign reports straight away.

2. Check the source page: the conversion should fire only after the action is completed.

3. Compare with real leads: count the forms, messages and calls you received in the same period and compare them with the reported conversions.

4. Review primary actions: make sure only the actions you chose in step one are set as primary.

5. Filter internal traffic in Google Analytics, and remember that an analytics filter does not remove test conversions recorded by a direct Google Ads tag. Keep a note of your own tests and leave them out of your lead count.

If the reported conversions and the real leads do not match, fix the measurement first. Changing bids, budgets or ads on top of wrong data only moves the problem.

Common conversion tracking mistakes

• Counting button clicks as leads. The bidding learns to find people who click, not people who contact you.
• Firing the tag on page load. Reloading, revisiting or bookmarking an unprotected thank-you page can generate duplicate conversion events.
• Too many primary actions. Several overlapping actions for the same goal inflate the totals.
• Forgetting the budget link. Measurement and budget planning belong together; our Google Ads budget guide explains how target conversions and cost per acquisition shape the spend.

Get your tracking checked

If your Google Ads account shows conversions that you cannot find in your inbox, or no conversions at all, start with measurement. Solya Agency works remotely with advertisers internationally. Send your website and a short description of what counts as a lead through the contact page, and we will plan the setup with you.
