We've added the Website IDs filter in the "Wayback Machine" section, which allows you to find domains owned by the same owner using identifiers from various services.
The system automatically detects IDs from more than 50 services, including Google Analytics (UA-XXXXX, G-XXXXX), Google Tag Manager (GTM-XXXXX), Google Ads, Facebook Pixel, advertising platforms, and other analytics tools.
The filter supports OR logic search — you can specify multiple IDs, and the system will find all domains using any of them. This is especially useful for researching domain portfolios and finding related sites.
