URL contains uppercase

Why it matters

URLs are case sensitive, so mixed case can create duplicate versions of the same page.

How to fix it

Use lowercase URLs and redirect uppercase variants to the lowercase version.

How Crawlune finds it

Crawlune flags URL contains uppercase automatically on every crawl and lists the affected URLs under theURL tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 500 URLs with every check enabled.
