If I have a website with 10 subpages, do I need a Trustlytics subscription for each page?

No, it is not necessary to subscribe to multiple subscriptions. Trustlytics can analyze a website, including all subpages and subdomains. For example, if you set up https://www.mydomain.com on Trustlytics, pages like https://www.mydomain.com/aboutme.html or https://www.mydomain.com/photos/album.html will also be taken into account. Even subdomains like https://blog.mydomain.com are included in the analysis.
