Google Ads Remarketing: strategies for activating existing customers

Return existing customers with personalized offers, cross-sell and loyalty programs. Build a repeat purchase lifecycle with data from CRM, Customer Match and automated audiences.

Difference: Remarketing vs. Retargeting

Remarketing

Communication to known contacts/customers (e.g. customer lists) for repeat purchases, upsell and loyalty – e.g. through Customer Match, email, etc.

On this page, we focus on remarketing to existing customers through Customer Match, primary data and audiences by lifecycle.

Retargeting

Target anonymous visitors based on their behavior on the site/app (viewed pages, products, abandoned cart, started form, etc.) through pixels/GA4 audiences.

  • Display, Discovery and YouTube video
  • RLSA (Remarketing Lists for Search Ads) for searching
  • Dynamic retargeting for catalogs

Note: In the Google ecosystem, the term “remarketing” often encompasses both. Here we deliberately differentiate by data source: anonymous traffic (retargeting) vs. known contacts (remarketing).
