How do you set up Google Ads conversion tracking?
The Short Answer
In Google Ads, go to Goals, Conversions and create a conversion action for each key event like a purchase or lead. Install the Google tag site-wide via Google Tag Manager, add event snippets or import GA4 conversions, turn on enhanced conversions, then verify with the tag tools before scaling.
Conversion tracking is what turns Google Ads from a click-buying tool into a performance channel. Without it, Smart Bidding has nothing to optimise toward and you cannot tell which keywords, ads or campaigns actually generate revenue or leads. Set this up before you scale spend, because every euro spent without tracking is data you can never recover. It is the single most important setup task in any account.
Start by defining your conversion actions. In Google Ads under Goals, Conversions, create one action per meaningful outcome: a purchase, a qualified lead form, a phone call, a booking. Assign each a value, choose count settings (every conversion for ecommerce, one per click for lead gen), and set the right conversion window. Mark only true business outcomes as primary, so bidding optimises toward money, not vanity clicks.
Install the Google tag across your whole site, ideally through Google Tag Manager. The Google tag handles the base measurement, and you add event-specific triggers for each conversion: a purchase tag on the order confirmation page, a lead tag on the thank-you page. For ecommerce, send transaction value and currency so the account can optimise to ROAS rather than to raw conversion counts.
Turn on enhanced conversions. This sends hashed first-party data like email from your conversion events back to Google, securely, to recover conversions that cookie loss would otherwise hide. In a world of consent declines and browser restrictions, enhanced conversions meaningfully improve match rates and bidding accuracy. Configure it through the Google tag or Tag Manager, and make sure it respects consent.
Decide how GA4 and Google Ads work together. You can track conversions natively in Google Ads, import them from GA4, or both. Importing GA4 conversions keeps one source of truth and gives you richer analysis, but avoid double counting the same action from two sources. Pick a primary method per conversion type and be deliberate about which conversions you import for bidding.
Verify before you trust the numbers. Use Google Tag Assistant and the conversions diagnostics in Google Ads to confirm each tag fires once, on the right page, with the right value. Watch the status move from Unverified to Recording. A tracking setup that looks live but double-fires or misses value will mislead every bidding decision you make afterward.
Step by Step
-
Create conversion actions for key events
In Google Ads under Goals, Conversions, create one action per outcome (purchase, lead, call), with the right value, count setting and conversion window. Mark true outcomes as primary.
-
Install the Google tag site-wide
Deploy the Google tag across all pages, ideally via Google Tag Manager, so base measurement is in place before you add event-specific tags.
-
Add event triggers per conversion
Fire each conversion tag on the correct page: purchase on order confirmation, lead on the thank-you page. Pass transaction value and currency for ecommerce.
-
Turn on enhanced conversions
Enable enhanced conversions to send hashed first-party data securely, recovering conversions lost to cookie restrictions. Make sure it respects user consent.
-
Decide GA4 vs native tracking
Choose whether each conversion is tracked natively or imported from GA4, and avoid counting the same action twice from two sources.
-
Verify with Tag Assistant
Use Tag Assistant and Google Ads diagnostics to confirm each tag fires once, on the right page, with correct value, and watch status move to Recording.

Frequently Asked Questions
-
Google Ads conversions feed bidding directly, GA4 conversions sit in analytics and can be imported into Ads. They use different attribution models, so the numbers rarely match exactly. Pick one primary source per action to avoid double counting.
-
In the EU, yes, practically. Consent declines and browser restrictions hide a growing share of conversions. Enhanced conversions send hashed first-party data to recover those, improving match rates and the accuracy of Smart Bidding.
-
Conversions can take a few hours to appear, and the status moves from Unverified to Recording once Google sees data. If nothing records after a day of clicks, the tag is likely misfiring or blocked, so check it with Tag Assistant.
