SEO Server Header Checker Tool

View HTTP/HTTPS headers, server responses and status codes. Server Headers is your one stop tool to quickly extract useful SEO data from a URL and pull in more 3rd party metrics. No need for multiple SEO tools, get the important information you need all in one place - with helpful links to dive deeper. I built this tool to help me quickly gather all the info I need about a URL when doing an SEO analysis or Audit.

Enter URL to check:

Select User Agent:    
Report Type:    Full (takes a few seconds)      Quick (no pagespeed or screen shot)

Prove you aren't a Bot:

Note: The Full Report includes Google MobileFriendly, Safebrowsing, and PageSpeed APIs and takes up to 1 minute to run. The Quick Report does not include mobile friendly data, page speed data, blocked 3rd party resources, safebrowsing, or the screenshot feature.
