This morning I’ve been conduction some research on class attributes that control search engine indexing, such as Yahoo’s no-content attribute.
Along the way I though I’d check Matt’s blog to see if Google have recently commented on the use of robots-nocontent so I performed this query to see if he had much content on the subject.
The results were pretty cool, but not in the way I had expected! Matt Cutts himself has duplicate search results with a non canonical form URL:
When you test the urls, for some reason Matt’s category and blog post urls don’t add / remove a trailing forward slash “/” via a 301 redirect though the main url (http://www.mattcutts.com/blog) does.
So, Matt, fess up! Are you still using your blog as a test case for canonicalisation issues, or is there something wrong with some of your .htaccess rules?
Heads up! :-)
