If you are using Google blogger you must setup 404 page redirections, if not this will affect your organic search results. I am using blogger since 2009 for 9lessons.info and I am not paying any hosting charges till today, I suggest everyone should start a blog with blogger. This post will explain you how to setup a blogger 404 redirection page in a simple way, now you can try here with wrong URLs.
Go to blogger and create a simple page with title Page not found.
Go to blogger Settings -> Search preferences
404 Page URL.
Copy the code inside the text box and click Save Changes.
