How to change title tag format in Blogger?

By default, Blogger syntax for any Post is {blog_name} : {Post_Name}.  This configuration affects Google Search Results. So to reconfigure Blog with only Post Title, follow the following steps:

1. Go to {your_blog} > Template > Edit HTML
2. Find the title Tag

   <title><data:blog.pageTitle/></title>

3. Replace it with following code

   <b:if cond='data:blog.pageType == "index"'> <title><data:blog.title/></title> <b:else/> <title><data:blog.pageName/></title> </b:if>

4. Use preview to check if there are any errors and SAVE.
