Google Ads Data Manager
Google's newer service for bringing first-party data and offline conversions into Ads, and now the route by which a conversion value reaches Google over an API.
Why it matters
It is not an alternative to the older upload service so much as its replacement. Google closed ConversionUploadService.UploadClickConversions to new adopters on 15 June 2026, and there is no application process to join the allowlist.
What goes wrong
Practically this is an operational change rather than a modelling one: a different endpoint, a different and sensitive OAuth scope, and a Cloud project that has to declare it. What a lead is worth and when a value may be restated are decided before any of it and do not move.

The rest of this step
Measure this on your own data
The diagnostic reads a CRM export in your browser and reports your volume, your match rate and the spread between your leads against the thresholds in this glossary. Nothing is uploaded and no account is needed.
