Conversion import from CRM
Conversion import from a CRM connects later, offline business outcomes — a qualified lead, an opportunity, a closed-won deal — back to the marketing click that started the journey. The click is captured with an identifier (such as Google's GCLID), stored in the CRM, and uploaded back to the ad platform when the outcome occurs. This lets optimization target real revenue events, not just form fills. This page explains the flow and its requirements.
How the flow works
When a user clicks an ad, the platform appends a click identifier (Google's GCLID, for example) to the landing URL. Your forms capture that identifier and store it on the lead record in the CRM. Later, when the lead progresses — becomes qualified, or closes — you upload the outcome plus the identifier back to the ad platform.
The platform matches the identifier to the original click and records the offline conversion against that campaign.
- Capture the click identifier (e.g. GCLID) at form submit
- Store it on the CRM lead record
- Upload outcome + identifier when the deal progresses
Requirements and pitfalls
The chain is only as strong as its weakest link: if the identifier is not captured, is stripped by a redirect, or expires before the deal closes, the conversion cannot be matched. Identifiers have validity windows, and long B2B sales cycles can outrun them.
CRM import lets bidding optimize toward genuine revenue rather than form volume — a major improvement in signal quality — but it demands disciplined identifier capture, consent handling, and timely uploads to work.
How it appears in analytics and logs
A conversion uploaded from a CRM means a stored click identifier was matched to a later business outcome; missing or expired identifiers break the link and the conversion goes unattributed.
Diagnostic use case
Optimize toward downstream value — sales-qualified leads or revenue — by feeding the ad platform the real outcomes recorded in your CRM rather than top-of-funnel form submissions.
What WebmasterID can help detect
WebmasterID can record the campaign and click context of a lead-generating session as a first-party event, giving you a clean origin record to reconcile against CRM-imported outcomes.
Common mistakes
- Failing to capture the click identifier on the lead form.
- Letting the identifier expire before a long sales cycle closes.
- Uploading CRM data without consent and retention controls.
Privacy and accuracy notes
CRM import handles personal data and click identifiers; it must respect consent, retention limits, and platform terms. This is educational, not legal advice.

- Offline conversion import
Offline conversion import (OCI) connects events that happen away from the website — a sales call that closes, an in-store purchase, a qualified lead in a CRM — back to the online ad click that began the journey. It works by capturing a click identifier (such as Google's GCLID) at the start and later uploading the offline outcome keyed to that identifier, closing the online-to-offline attribution loop.
- Phone call conversions
Phone call conversions count phone calls as conversions and attribute them to the ad or campaign that drove them. Ad platforms use call extensions with dynamic forwarding numbers, or track clicks on a phone-number link on the website, to connect a call back to its source. This page explains how call tracking works, what it can attribute, and the privacy considerations around recording or measuring calls.
- Attribution and bid strategies
Automated bidding optimizes toward the conversions it is told to value — and the attribution model determines how that credit is assigned across the path. Switching from last-click to data-driven attribution, for example, changes which keywords and audiences get credit, which in turn changes how Smart Bidding allocates budget. This page explains the tight coupling between attribution model choice and bid strategy behavior.
