The source and the change
Google’s December 2022 announcement described data-driven attribution using account history to distribute conversion credit across ad interactions. It also introduced more ways to inspect the model’s effects. That is the source event covered here, not the date this GTMhub analysis was first published. Original Google announcement.
The decision for a B2B team
Start with the outcome that receives the credit. A model trained against completed forms can give a sophisticated account of how those forms happened while saying little about qualified pipeline. Attribution and qualification solve different problems. The first assigns credit; the second determines whether the business event belongs in the number you are optimising.
Our recommendation is to trace one accepted opportunity back through the measurement chain before changing an attribution setting. Check the account match, accepted stage, value, event time, conversion action and reporting period. Repeat with an inquiry sales rejected. The two should remain distinguishable all the way to the campaign decision.
What to inspect before changing budget
| Question | Useful evidence | Decision it supports |
|---|---|---|
| What counts as qualified? | A sales-accepted stage with an owner and explicit exclusions | Which event should inform optimisation |
| Are outcomes mature? | Cohorts grouped by acquisition date and expected sales lag | Whether a recent campaign can be compared fairly |
| Is value meaningful? | Won-deal values or a documented stage-value model | Whether value-based decisions are justified |
| Are events distinct? | Stable event IDs and reconciliation counts | Whether reported growth is actually duplication |
Use it in your own account
Write down one pipeline definition with sales and finance. Map the qualified event into the measurement contract. Keep the current campaign history and changes that already work. Compare a bounded change against a mature cohort rather than treating a before-and-after platform screenshot as causal proof.
A missing outcome is not a zero-value outcome. If the CRM does not yet contain the result, keep it unknown and report the lag. Otherwise the newest cohort may look worse simply because sales has not had time to work it.
Current implementation note
For a new Google Ads integration, use current platform instructions rather than the API setup implied by an old announcement. Google changed offline-import access for new adopters in June 2026; our offline conversion workflow explains the current path. The durable lesson from the 2022 source is to agree the commercial event before arguing about its share of credit.
