HTTP Headers Checker Tool

What is an HTTP Headers Checker?

An HTTP headers checker is a tool that shows the hidden information a website sends when you visit it. These headers include server details, security settings, caching rules, and performance data.

Every website sends HTTP headers before the page loads. These headers control how browsers and search engines interact with the site.

Why HTTP headers are important

HTTP headers affect website performance, SEO rankings, and security. Poorly configured headers can lead to slow load times, security risks, or indexing issues.

SEO professionals and developers use header analysis to optimise websites and ensure proper server configuration.

Security headers explained
