Uppercase Characters in URL

What This Means

The URL path contains one or more uppercase characters (A-Z). URL paths are case-sensitive on most web servers, meaning /Page/ and /page/ are treated as distinct URLs.

Why It Matters for SEO

Uppercase characters in URLs create the potential for duplicate content: links to /Page/ and /page/ may both resolve to content, creating two indexable URLs with the same content. They also look inconsistent in link shares and analytics.

What the Platform Checks

Checks the URL path for uppercase characters (A-Z). Fires when any are found.

How to Fix It

• Redirect uppercase URL variants to lowercase equivalents (301 redirect).
• Configure your web server to enforce lowercase URLs: Apache RewriteMap or Nginx map + return 301.
• In CMS: configure URL generation to always use lowercase slugs.
• After implementing server-level lowercase enforcement: update any internal links that use uppercase paths.
