I have found an easy Blogger Trick that helps you get comments. Basically the comments that you get are manually made by you and commented. Your blogger ID does not appear during the comment. This trick will let you make your own comments and post it to Blogger posts with different names.
1.Go to 'Design' after logging into Blogger.
2.Go to the 'Settings' tab.
3.Choose the 'Comments' sub tab.
4.Change 'Who Can Comment?' from 'Registered Users' to 'Anyone'.
5.Click on 'Save Changes'.
6.Log out of Blogger.
7.Open your post.
8.Comment on it using the 'Anonymous Option'.
Now you can insert a random name and comment yourself on your Blogger post without letting anyone know. For more assistance take help of this video:
