Trust anchor pages

What it checks

The extension looks for three pages: about, contact and privacy. For each one it first uses a link the page actually publishes (any link on the same site whose URL or text mentions “about”, “contact” or “privacy”), then tries common paths. Links to other domains are never followed:

Page	Paths tried
About	/about, /about-us, /company
Contact	/contact, /contact-us
Privacy	/privacy, /privacy-policy

A page only counts if it returns a successful response with at least 500 characters of text. Shorter pages are reported as too thin to count.

Some sites answer every path with a 200, even ones that do not exist. The extension detects this by requesting a path that cannot exist (the same one the Agent-friendly 404s check uses). On those sites, a candidate page only counts if its wording is clearly different from that catch-all response, so the homepage served at /about is not mistaken for an about page.

Results

Status	When
Pass	All three pages exist with at least 500 characters of text
Warn	At least one exists with real content, but another is missing or too thin
Fail	None of the three was found with real content

How to fix

Publish real about, contact and privacy pages, each with at least 500 characters of content, and link to them from every page, typically in the footer:

<footer>
  <a href="/about">About us</a>
  <a href="/contact">Contact</a>
  <a href="/privacy">Privacy policy</a>
</footer>

Linking them means the extension, and an agent, can find them whatever URL you use. If your site returns 200 for missing pages, fix that too: it makes these pages harder to tell apart from the catch-all.
