Redirect and 404 Analysis

The redirects and 404 analysis reports on problematic URLs, focusing on 404 errors and redirects (301/302). This helps identify broken links and unnecessary redirects, which can negatively impact user experience and SEO.

  • Status: Displays the HTTP status code of each URL. 404 indicates a broken link, while 301 or 302 indicates a permanent or temporary redirect.
  • URL 404/Redirected URL: The specific URL that encountered the 404 error or was redirected.
  • Target URL: The final destination URL after the redirect.
  • Found at URL: The page where the broken or redirected link was discovered. This helps identify the source of the issue for easier identification and resolution.

The analysis provides a summary of skipped URLs, including those that werenโ€™t crawled due to various reasons:

Skipped URLs Summary
--------------------
Reason | Domain | Unique URLs
------------------------------------------------------
Not allowed host | nextjs.org | 1294
Not allowed host | astro.build | 925
Not allowed host | www.netlify.com | 711
Not allowed host | cdn.sanity.io | 301
Not allowed host | storage.googleapis.com | 142

For 404 errors, the analysis generates a table showing broken links:

404 Errors
----------
Status | URL | Found at URL
---------------------------------------------------------------------------
404 | /html/2024-08-24/forever/httpAgentOptions | /html/2024-08-23/forever/cl8xw4r-fdag8wg-44dd.html

For redirects, it shows the chain from original to target URL:

Redirects
---------
Status | Source URL | Target URL | Found at URL
------------------------------------------------------------------------------------------
301 | /old-page/ | /new-page/ | /links/
302 | /temporary-promo/ | /current-offer/ | /home/

These tables help you:

  • Identify and fix broken links that affect user experience
  • Optimize redirect chains to reduce page load times
  • Understand external domain dependencies and their impact
  • Prioritize fixes based on which pages contain problematic links
