Earlier this week, we showcased an example of an SEO issue that Moz was having. Now John Mueller of Google has come into the Google Webmaster Help thread to offer his advice.

The interesting part is that it seems that this is Google trying to be smarter and not listen to the 301 redirect directives set in place by Moz.

GoogleBot learned that it can pick up and index content for the /blog/ URL structure by going to the /ugc/ structure. Despite the 301 redirects Moz has in place, it seems to be just taking the /ugc/ structure. John said this is very rare to see.

John explained:

So return 404s on the URLs that are 301ing. I am not sure if that would work because Moz may often upgrade /ugc/ content to /blog/ content and then they need the 301 to send the user to the right URL.

John then explains that this is a rare case and most webmasters do not have to worry about this:

This is one of those interesting cases that are awesome to document.
