How it works
How to use HTTP Response Header Parser

        

                            
Copy response headers
Open the Network panel in your browser developer tools and copy the response headers as text. Paste up to 1 MB and 1,000 lines.

                            
Inspect each response block
Keep HTTP status lines when available. Up to 20 blocks are accepted; repeated fields remain separate instead of being silently overwritten.

                            
Review SEO signals in context
Check Location and every X-Robots-Tag value, then inspect the real destination, page HTML and Search Console separately. A response header is only one signal.

How do I use HTTP Response Header Parser? 
1. Copy response headers: Open the Network panel in your browser developer tools and copy the response headers as text. Paste up to 1 MB and 1,000 lines. 2. Inspect each response block: Keep HTTP status lines when available. Up to 20 blocks are accepted; repeated fields remain separate instead of being silently overwritten. 3. Review SEO signals in context: Check Location and every X-Robots-Tag value, then inspect the real destination, page HTML and Search Console separately. A response header is only one signal.

                            
Does this check a live URL or redirect chain? 
No. It parses only the text you paste. Multiple blocks are shown in the supplied order; their connection, destination availability and authenticity are not verified.

                            
Can this prove that Google will index the page? 
No. A 200 response does not guarantee indexing, and missing X-Robots-Tag fields do not establish indexability. Robots meta tags, robots.txt access, canonical selection and content quality need separate review.

                            
What is retained in the exported report? 
Field names are lowercased and values remain plain text, including repeated fields. Link headers are not parsed into canonical or hreflang relationships. Remove credentials and cookies yourself before sharing the JSON report.
