Security
Server version disclosure
Why it matters
Headers that reveal exact server or framework versions make it easier for attackers to find known vulnerabilities.
How to fix it
- Hide version numbers in Server and X-Powered-By headers (for example ServerTokens Prod in Apache).
Check it with
- HTTP Headers Checker – View all HTTP response headers for a URL, with notes on the ones that matter for SEO.
Scoring: a passed check earns its full weight, a warning half and an error none. How the SEO score works
