Audit URL capitalization and help standardize paths to lowercase. Review routes, internal links, and sitemaps, then check that uppercase variants permanently redirect to the lowercase address to reduce duplicate page URLs.

Use when auditing URL structure or configuring a new site's routing. Applies to any server or framework that allows case-insensitive file systems (Linux servers are case-sensitive by default).

Mixed-case URLs can create duplicate content—search engines may index both /Product and /product as separate pages, splitting link equity and diluting rankings.
Scan the site's internal links and server-side routes for URLs containing uppercase letters. Check HTTP response codes for uppercase variants of key URLs to confirm whether they redirect (301) to lowercase.
Configure your server or framework to normalize all incoming URLs to lowercase before routing. Add 301 redirects from any existing uppercase URLs to their lowercase equivalents. Update internal links and sitemaps to use only lowercase URLs.
URL case matters for SEO because case-sensitive servers treat /Page and /page as different resources, creating duplicate content. Even on case-insensitive servers, inconsistency confuses crawlers and splits PageRank across URL variants.
Scan the site's route definitions, server configuration, and internal links for uppercase letters in URL paths. Test key URLs in uppercase and mixed case — verify they return 301 to the lowercase version, not 200. Check the sitemap for any uppercase <loc> entries. Verify framework router is configured to normalize URL case.
