I was checking some of my awesome rankings in Yahoo! this morning (kidding, of course) and I noticed Yahoo! has been messing with the titles they use.
In the past Yahoo! defaulted to showing the title created in the Yahoo! Directory listing (if available) in the organic search results page. So my site's listing in Yahoo! Search looked something like this:
Now if you do a search on rustybrick at Yahoo! Search, I saw my title specified in the source displayed.
Yesterday, I did not see this, just now. Same for search engine roundtable and other sites. I have a feeling I can expect my CTR to climb in Yahoo! for some of my sites, as should you, if this sticks.
I posted a thread on this topic at Search Engine Watch Forums.
