Google Ads Offline Conversion Tracking
Connect offline sales back to Google Ads clicks for closed-loop attribution.
Close the attribution loop with Google Ads offline conversion tracking. Upload CRM sales data to Google Ads and optimise bidding toward actual customer revenue.
Adslytics implements Google Ads offline conversion tracking using the Google Ads Offline Conversion Import (OCI) system. We capture the GCLID (Google Click Identifier) at every online touchpoint — form submissions, chat initiations, call initiations — and store it alongside the lead record in your CRM. When the lead converts to a customer, the GCLID is uploaded back to Google Ads with the conversion event and revenue value, closing the attribution loop. We configure GCLID capture on all relevant forms, build the CRM field mapping, create the offline conversion action in Google Ads, and set up the upload mechanism — manual CSV, Google Ads API, or automation via Zapier or Make. The result is campaign reporting that reflects real business outcomes.
