What type of users would an advertiser reach with a remarketing audience?

A remarketing audience in Google Ads is built from your data segments, which use first-party interaction data to reconnect with people who already engaged with the business. For Display, one of the standard segment types is website visitors collected through the Google tag. That means the campaign is reaching users based on prior site activity, not on inferred intent, broad interests, or modeled similarity. This makes website visitors the correct match for a remarketing audience
