The capitalization of URLs is crucial in technical SEO as Google treats uppercase and lowercase URLs as entirely different pages. For instance, URLs like /services/digital-pr/ and /Services/Digital-PR/ would be considered separate, leading to duplicate content issues.

To prevent this, implement global redirects (e.g., through .htaccess) to ensure all URLs are in a consistent format, typically lowercase.

If you're seeing your URLs able to render at multiple capitalization variations, this should be an immediate red flag. You'll want to work with your developers to ensure that all the URLs on your site can only be accessed through a single URL format.
