Region Map - EPA OSC Response LockPrimary navigation

Region Map describes itself simply: "Jump to main content An official website of the United States government Here’s how you know Here’s how you know Official websites use.gov A.gov website belongs to an official government." Measured against the twelve signals AI engines rely on, it scores 7.3 out of 10, a strong showing.

On the page it is passable on a workable page structure and partial sitemap and link coverage. What holds it back is a clearly stated business identity, the technical files AI engines look for, such as llms.txt or an open robots.txt, structured data describing the business and credibility markers like credentials or reviews.

Off the page, other sites link to it, the domain reads as established, AI engines recognise it as a distinct business, it turns up in press coverage, people discuss it in places AI engines read and it comes up on Reddit.

AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic). It does link out to several social profiles, which helps engines tie the brand together.
