Multi-Domains

Multi-Domains power-up lets you use one sGTM container for server-side tracking across multiple domains, such as mysite.com and mysite.ai. Each domain keeps its own first-party tagging URL, while you manage the server-side setup in one place.

Multi-Domains is available on Stape Business plan and higher. The limit is 20 domains with Business or Business+. With Enterprise or Enterprise+, the limit is 50 domains, and custom plan limits are set individually.

Find Multi-Domains in the Power-Ups tab and follow the Multi-Domains setup guide to add and verify your domains.

Multi-Domains connects several tagging server domains to one sGTM container hosted on Stape. Each website sends data to its own tagging server URL, and Stape routes these requests to the same container.

This lets related websites share one server-side tracking setup while keeping the right first-party domain for each website.

• Manage several domains under one sGTM container. Use Multi-Domains to connect several tagging server domains to one sGTM container when your websites need similar tracking logic.

• Keep first-party cookies for each domain. Let each website keep its own cookie data and send more complete attribution signals.

• Reduce repeated setup work. Keep shared tags, triggers, and variables in one sGTM container instead of creating a separate server container for every related website.

• Support country and language websites. Use Multi-Domains when your business has separate domains for different markets, such as example.com, example.es, or example.de.

Connect several tagging server domains to one sGTM container and avoid creating a separate server container for each website.
