This query gives a result I hadn't seen before (image), the same page was indexed with both a single trailing forward slash, which is of course normal, and with a double trailing forward slash... This is of course a duplicate content issue, especially when people link to the double slash one by accident. The fix for it in Apache is quite easy, just add this to your server config or htaccess:
RewriteEngine On
RewriteCond %{REQUEST_URI} ^(.*)//$
RewriteRule . http://yoast.com%1/ [R=301]





Hi Joost,
Thanks for that, I had a site where /, was being indexed (strange).
Have used your solution to fix it.
Thanks again.

Hi Joost, do you think that would be useful if the "//" are showing up not in the serps, but in the google analytics? thanks...
