Header Checker

Header checker:

When it comes to website security and optimization, the smallest detail counts — even your HTTP headers. Headers may be invisible to everyday users, but they play an important role in the server, browser, and search engines interacting with your site.

The purpose of our header checker tool is to help you in checking and analyzing the HTTP response headers of any web page or URL. As an SEO specialist, web developer, or site administrator, this tool can help you determine the performance, search engine rankings, and site security affecting your site by providing the major server-side information.

What Is a Header Checker?

A Header Checker is an online utility whereby you can see the HTTP headers that are returned from a web server when a request is issued. These headers carry important metadata regarding the web page — its status, server type, caching policy, content type, redirect behavior, and so on.

Using our Header Checker

You can easily check why a page is acting up, inspect for redirect chains, find server settings, and verify your SEO configuration is correct.

Why HTTP Headers Are Important

With every visit from a user or bot to your site, the browser initially receives HTTP headers before loading content. HTTP headers can affect:

• Redempted behavior (eg, 301 vs 302 redirects)
• Safety Settings (eg, material-protection-policy, HSTS)
• Material delivery (eg, Gzip compression, caching)
• SEO (e.g., canonical tags, language tags)

Our Header Checker assists you in debugging and understanding more about how your website is being delivered to browsers and search engines.
