4) Set Up via Google Tag Manager (Recommended)

Google Tag Manager (GTM) lets you deploy and maintain tags without editing code on every page. Create a Google Ads Conversion Tracking tag, paste your Conversion ID and Conversion Label, then trigger it on the conversion event (e.g., thank-you page view, button click, or form submission).

Open GTM and select your container.
Click Tags → New → Google Ads Conversion Tracking.
Enter your Conversion ID/Label from Google Ads.
Select a trigger (page view or click/form event).
Preview, then Submit and Publish.

✅ Assign values (static or dynamic) to understand revenue impact.
✅ Link Google Analytics → Google Ads for deeper attribution.
