By default, Blogger assigns title tags which contain the the Title of the post following the Name of the blog . But this type of title tags are not search engine friendly. The main problem with them is that, they eat up your more valuable characters in the Blog Post titles. Google by default gives search results which are not more than 80 characters in length. So, when your Blog name precedes your Post Title, then you might miss out on some keywords present in your Post title (if post tile + blog name is more than 80 characters) which might help in bringing more traffic to your blog.
Thus a precious piece of search engine real-estate often goes wasted, preventing many of your articles from appearing on the first page of Search Results even if the search terms match up perfectly with the article title. To improve on this and to correct this error, a simple HTML recoding proves to be helpful.
