You can track multiple websites in one Tracking container with simple implementation.
Cross-domain tracking is essential if your business operates across multiple websites or subdomains. It ensures that customer interactions are correctly attributed and linked to the same user, improving your data accuracy and marketing performance. Here’s why enabling cross-domain tracking can benefit you:
If you track subdomains: the DNS settings need to be done for the main domain (only).
If you track multiple separate domains (not subdomains), DNS settings should be configured for each domain individually, while all domains point to the same Tracklution container backend.
For example, if you are tracking websiteA.com and websiteB.com, the CNAME should be added twice. Both should be pointing to the domain that is under your container's "First-Party Mode"-tab.
Both domains use the same Tracklution container and are now able to share sessions reliably using first-party tracking.
If you have multiple different Shopify stores and you want to track all of them inside one Tracklution container, use the same code from the installation instructions with a little tweak.
