Can one server-side tracking setup handle multiple websites? TAGGRS has developed the TAGGRS Multi Domain Tool, you can streamline server-side tracking for all your web properties within a single Google Tag Manager (GTM) container. This feature enables accurate attribution, consistent measurement, and seamless cross-domain user journey analysis, even across multiple domains, landing pages, or websites in the same niche. This guide will show you how to set it up effortlessly and when it’s the right solution for your multi-site environment.
When TAGGRS Multi Domain Tool does use:
Multiple separate domains such as, for example, taggrs.com / taggrs.de / taggrs.fr.
Landing pages: You have several landing pages on separate domains that redirect you to a main site
Similar niche: Different websites within the same niche
When not using TAGGRS Multi Domain Tool:
If you work within a single domain that uses geographic or language-specific subpaths, such as taggrs.co.uk/de or taggrs.co.uk/en. In these cases, tracking within the same domain is sufficient.
- Active TAGGRS account
- GTM web and server containers set up
- List of domains and subdomains to track
In the TAGGRS dashboard, navigate to the Multi Domain Tool section.
1. Enter each domain and subdomain you wish to track.
2. Validate ownership as required (e.g., by DNS record or HTML file upload).
1. Ensure GTM containers are deployed on all domains/subdomains.
2. Use the Multi Domain Tool to synchronize user identifiers and cookies across domains for unified tracking.
Use GTM Preview mode and analytics diagnostics to confirm that events and user journeys are accurately tracked across all domains.
Unified analytics: Track users seamlessly as they move between domains and subdomains.
Accurate attribution: Prevent loss of conversion data due to cross-domain navigation.
Centralized management: Control all tracking from a single GTM container.
Regularly audit your domain list for new or removed properties.
Ensure privacy and consent settings are consistent across all domains.
Monitor analytics reports for gaps in cross-domain attribution.
Issue / Solution
Missing data on subdomains / Verify GTM deployment and domain validation
Attribution gaps / Check cookie synchronization and user ID mapping
Validation errors / Recheck DNS or HTML verification steps
