URL: Uppercase

URLs that have uppercase characters within them. URLs are case sensitive, so as best practice generally URLs should be lowercase, to avoid any potential mix ups and duplicate URLs.

How to Analyse in the SEO Spider

View URLs with this issue in the URL tab and ‘Uppercase’ filter, and export all URLs using the ‘Export’ button.

Use the lower ‘Inlinks’ tab to view pages that link to them.

What Triggers This Issue

This issue is triggered when a URL includes uppercase characters. For example:

https://www.screamingfrog.co.uk/Froggy/

How To Fix

Ideally lowercase characters should be used for URLs only.

However, changing URLs is a big decision, and often it’s not worth changing them for SEO purposes alone.

If URLs are changed, then appropriate 301 redirects must be implemented.
