I am working on a site that has a lot of dynamically created pages that have uppercase letters in the url. They are long urls and will probably never be typed in by the user. I know it is best practice to use all lower case but there are a lot of these pages already out there. My big question is does it hurt my SEO to have the uppercase letters and should i change them.
Here is an example. mysite.com/Article-Satellite-Internet-Now-Available-in-Ragland-AL/01/RAGLAND/12.htm
