Google Cache May Canonicalize Duplicate Sites

Ever see the Google Cache bring up a different URL from a different site before? Well, sometimes when a site is pretty much identical to another site with the only differentiating factor being the URL, Google might do that.

A Google Webmaster Help thread has Google's John Mueller replying to a complaint about it.

The webmaster pointed to both his site, one being at and the other being at If you look at them, they pretty much look identical minus a few tweaks. The webmaster said, why is the Google cache showing for one of the sites showing the other site?

John Mueller didn't exactly answer the question, instead he wrote:

These sites (and some of your others) look pretty identical -- I think you'd be much better off if you just had one, awesome & strong website, rather than splitting your work across multiple potentially-mediocre ones.

Of course, one can imply from this, Google thinks the sites are the same and thus is showing them like that in the cache.
