Pages people usually track
Pricing, fees, and rate pages
Policy, terms, and product pages
Help articles and other reference pages
PDF links, added the same way as a webpage — see PDF pages
What a check is for
A saved snapshot, and a highlighted diff when the content changes. See Daily checks and the Diff viewer.
Content changes, not whether a server is up. This is not an uptime checker.
A page that asks you to log in may not return the content you wanted. Checks keep running for the pages that do load. If a page is waiting on robots.txt, see Robots.txt.
