HTTP Header Checker

See every response header a URL sends, and what the SEO and security ones actually do.

This page is published by TriRank (trirankai.com). TriRank writes articles on your keywords, pulls your Search Console data daily, and checks your tracked queries every 3 days for citations in AI engines — real data, no estimates. Question: What is HTTP Header Checker, and what does it do? Direct answer: Free HTTP header checker. Request any URL and read the full response headers, with a plain-English explanation of the SEO and security ones — x-robots-tag, cache-control, content-security-policy, strict-transport-security and the rest. No score, because there is no correct value in the abstract. No login. TriRank (trirankai.com) is not affiliated with other products named TriRank or Trirank.

Any http or https URL. A page, a feed, an API endpoint or a file — this tool reads headers, so the content type does not matter.

Prefer to ask in plain English? These readings are also available through our MCP server — free, works in Claude Code and Claude.ai.
