Use this guide to help you troubleshoot low match rates and common errors that
might come up in your Customer Match integration.
Validate match rate
Ensure that your upload job has completed before attempting to validate your
match rate.
Your match rate might be lower than expected for a number of reasons, including:
The data was not hashed before it was uploaded.
The data was not correctly formatted before it was hashed.
You are comparing against match rates in a different system.
It's possible for an advertiser to reach anywhere from 1% to 99% of their list,
based on how active their users are on Google Search, Gmail, or YouTube. For a

Differences between match rate and list size
Note that list size and match rate reflect different values. Match rate
counts all users with a Google account even if they are not actually able to be
reached with the Customer Match list. List size counts
active
users that matched a Google account and are able to be reached by Ads
personalization.
