Thoughts on Results from Changing Title Tags

[TopFloor]

A number of the client's we represent have seen drops in rankings.  The title tags on these sites are formatted old way of doing tilte: "Blue Widgets| Cheap Widgets | Metal Widgets".

We are going to change them to the natural format: Acme Offers Blue, Metal Widgets for Any Budget."

Just wondering if anyone has made similar changes post-penguin and if they've seen improved ranking from doing it.

Sometimes not being consistent helps. Just my 2c. I would look at if there were other reasons. Are your off-page factors pretty well competitive. Did you get a unnatural links warning ? If after all those answers, you still think it's the page titles, change them on a handful of pages and see if you see any movement at all in the SERPS before investing a lot of time, effort and resources in this.
