To find 404 errors and missing 301 redirects after a CMS migration, you need to audit your domain for URLs indexed in search engines that now return a 404. This process detects broken redirects and suggests accurate _redirects file entries to restore proper mapping.

Detecting indexed 404s helps preserve SEO rankings by identifying old URLs that lost their link equity due to missing 301 redirects. Generating accurate redirect entries for these URLs restores the mapping to new ones, preventing search engines from dropping your pages from their index.

You can automatically generate _redirects entries for broken URLs by executing an audit script against your domain and processing your existing redirect files. This identifies 404 errors and suggests the missing 301 redirect mappings to fix them.

The best way to audit a domain for missing 301s post-migration is to run an automated audit script that checks indexed URLs for 404 responses. Processing existing redirect files alongside the script execution allows it to suggest accurate mappings for the missing 301s.

Yes, you need existing redirect files to suggest accurate 301 mappings. The audit process requires processing your current redirect files to identify gaps where 404 errors occur and generate correct _redirects entries for those missing URLs.
