URL Mixed Cases and Duplicate Content

[Midleton]

Hi There,

I have a question for you. I am working on a website where by typing any letter of the URL in lower or upper case, it will give a 200 code.

Examples

www.examples.com/page1/product

www.examples.com/paGe1/Product

www.examples.com/PagE1/prOdUcT

www.examples.com/pAge1/proODUCt

and so on…

Although I cannot find evidence of backlinks pointing to my page with mixed cases, shall I redirect or rel=canonical all the possible combination of the cases to a lower version of them in order to prevent duplicate content? And if so, do you have any advice on how to complete such a massive job?

Thanks a lot

It makes more sense to make a server level rule that will 301 any mixed case to a lower so if a URL is being accessed on anything other than lowercase it will redirect to the lower case URL.

This should save you some effort in the long run.

Have a look around many other sites, and they all do the same. Do a search for something in Google and then change the case of anything after the domain. Microsoft is the same. I am sure that there are examples that will 404 these requests, and that will then be a server side setting.

I really wouldn't worry about that though. MOZ is the same as well. Upper or lower case will give you the same page. in the last 15 years of SEO, I have never come across this as an issue

Hi,

Technically this is duplicate content, but it is most likely something search engines understand to ignore (especially if no links point to the upper case / incorrect URLs). If it particularly bothers you, place a self-referencing canonical tag in the page's file so that www.examples.com/pAGe/PROducT references www.examples.com/page/product in its tag. Either that or a 301.

Cheers.
