Last week, we asked if Google was picking titles from Google Maps? It turned out to not be the case. In fact, there has been a surprising number of people complaining about the titles Google is showing for a specific page in the search results.
A newer thread at Google Webmaster Help brings up a new case where a search for http://www.animationarena.com/best-animation-schools.html returned a title that read "Schools that teach Flash - Best Animation Schools" as opposed to just "Best Animation Schools." It seems to be fixed for me now, but JohnMu of Google did chime in.
John said:
There are certain situations where we'd replace a title in search results (as is happening here), for example if we find that the same title is used on a number of pages or if the title is otherwise not that good (eg "Home"). It looks like in this case we chose a weird title -- I've passed it on to the team so that they can take a look and adjust things if possible.
Now, John replied with a similar message to several other threads or blog posts. Google must have done something recently which caused many titles to be overwritten by what Google thinks would be a more appropriate title.
Let's explore what John said a bit more. A different title may be used in the Google search results if:
(1) "The same title is used on a number of pages," a duplicate content title adjustment?
(2) "The title is otherwise not that good (eg "Home")", which we knew for a while now.
The first one is most interesting to me and I personally have never seen Google admit before.
