Duplicate page titles are the same URL listed twice

[loopyal]

The system says I have two duplicate page titles. The page titles are exactly the same because the two URLs are exactly the same. These same two identical URLs show up in the Duplicate Page Content also - because they are the same.

We also have a blog and there are two tag pags showing identical content - I have blocked the blog in robots.txt now, because the blog is only for writers. I suppose I could have just blocked the tags pages.

Oh, and the trailing slash of course - thanks for the reminder!

If you think it's a software error you might be best contacting support directly. Have you checked for similar errors in Google and/or Bing Webmaster Tools?

Thank you for the fast response, Alex.

They are character for character exact matches, both with a trailing slash

http://domain.com/

All other variants are 301 redirected to that url,

except uppercase/lowercase, which gets a 404 error response.

Are you sure the URLs are exactly the same? The following are all different URLs:

• examplesite.com
• www.examplesite.com
• www.examplesite.com/index.html
• www.examplesite.com/Index.html (note the capital 'I')

If they are different it's best to 301 redirect one to the other, or if that's not possible - add canonical tags to the two pages linking to your preferred version. Other than that, make sure you only use one unique URL throughout your site to link to one page.
