In my previous post on title optimization , I discussed about that title of the post should get displayed as Post title + Blog title to get better search engine ranking.
I found one such widget at http://widget-based.blogspot.com/. It is for blogspot users.
After installing this your post title will get displayed as Post title + Blog title.
But I also found one problem with this widget i.e. after installing this widget when I go to Layout and try shifting the position of page elements and click save , it does not save the changes.
Please do not use this widget for title optimization , if you already have good search engine ranking.
