If you Google Keyword Tool today instead of the usual “Google AdWords: Keyword Tool” title showing up in the SERPs a less helpful and informative “Untitled” appears.

Going to the page reveals that the page title is not blank or set to untitled.

Any ideas why this would happen? Let us know in the comments!

UPDATE:
I found another!

While search in for “diamond football international” I found the title “nbsp; |   &nbsp – Diamond Football International”. I now think Google is changing the way results appear in the SERPs, instead of just the content from the title tag appearing as the result title it take content from other sources including the H1 tag of the page and content from other pages.
