Note: This script is not only for blogger blogs, but for every webpage to optimise in search engines, one thing is most important which is your content, you cannot take your site higher in search by only using this script in your html editor, your content should be more powerful, unique, genuine and compitent, google prefer those websites, where content is powerful and innovative than other things.
