Not sure if anyone else has come across this, but if a site has the same page title sitewaide, it appears that in some cases, google is creating their own titles based on page content.
Impossible to say if this is the title being used for ranking, or if it is just for display, (as in when it uses the ODP (DMOZ) titles).
Interesting find though 🙂
Nice find indeed. Do you have a search URL where you can see this happening?
I checked a few on Google Australia, not finding any yet 🙁
I will try and find a serp with it on. but I don’t want to identify the individual site 🙂
