    Customer Match audiences are powered by a business’s customer data, such as emails, that is uploaded to Google Ads. Google then matches these emails with user data to deliver relevant ads to your customers.

    Previously when an advertiser uploaded customer data as an audience, they would not know how many matches they would get. However, this new update will show an estimated match rate on upload.

    This means that advertisers will have an idea on the size of their Customer Match audiences before they have fully populated which could be useful for campaign forecasting and understanding the reach that your audience will have.
