What is Google Ads Remarketing?

The Google Ads Remarketing destination syncs customers from Masivo audiences into a Google Ads Customer Match user list. You can then use that list for remarketing and lookalike-style campaigns in Google Ads. This integration is separate from Google Ads conversion upload. Remarketing syncs audience membership; conversion upload sends purchase and event conversions.
Remarketing uses the Google Data Manager API with OAuth and a GCP project. It does not require a Google Ads developer token.

​

Integration type

​
Destination (audience sync)

When enabled as a destination on a Masivo audience:
  • Add: Customers entering the audience are uploaded to your Google Ads user list
  • Remove: Customers leaving the audience (or delete signals) are removed by hashed email
  • Background processing: A cron worker drains the google-ads-remarketing queue in batches

​
Data flow

1

Audience update

A Masivo audience is created, recalculated, or a member is added/removed.
2

Enqueue

Destination jobs are enqueued on the google-ads-remarketing queue.
3

Process

The cron batches members, hashes identifiers, and calls Data Manager audienceMembers:ingest or audienceMembers:remove.
4

Google Ads

Members appear in your Customer Match user list for campaign targeting.

​
Identifiers sent

At least one of email or phone is required for an add. Removals require email only.
