Conversion & attribution
What is Offline conversion tracking?
Importing conversions that happen off the website (a closed sale, a qualified lead in the CRM) back into ad platforms so bidding optimizes for revenue, not form fills.
Definition
Offline conversion tracking (offline conversion import) feeds conversions that occur after the website — a lead that became a paying customer in the CRM, a phone sale, an in-store visit — back into ad platforms by matching on a click ID (GCLID/GBRAID) or hashed identifiers.
It closes the loop between the ad click and the actual revenue outcome, so the platform can optimize toward customers, not just form submissions.
Why it matters for agencies
For lead-gen and high-consideration clients, optimizing toward form fills is optimizing toward the wrong thing — many leads never close. Offline import lets the agency optimize toward qualified, closed revenue.
It’s also one of the harder things to keep healthy: it depends on capturing and storing the click ID at lead time and a reliable CRM-to-platform sync, both of which break quietly.
Offline conversion tracking in Phloz
Phloz models the CRM and the conversion endpoints as nodes with a `syncs_leads_to` / `reports_conversions_to` relationship, so the offline-import path is something you can see and verify rather than a hidden script nobody owns.
Frequently asked questions
- What’s a GCLID and why does offline import need it?
- The GCLID (Google Click ID) is the token that ties a click to a campaign. Capturing it on the lead form and storing it with the lead is what lets you later tell Google "this specific click became a $5,000 customer."
- Is offline conversion tracking worth the setup?
- For ecommerce with on-site purchase, often not. For lead-gen, B2B, and high-ticket services where the sale closes later, it’s frequently the single biggest improvement to bidding signal an agency can make.
