Dofollow blogs are those blogs which have Dofollow plugin installed. It removes “Nofollow tag “ from comments. That means if you comment on those blogs then search engines like Google and yahoo will count your homepage link as backlink. This way if you comment on Dofollow blogs then it will keep creating backlinks which in turn increases your pagerank as well as effects your ranking in search results of Google.
Here is a list of DoFollow blogs on which you can comment. I am not hyperlinking them so you have to copy paste those links into your browser or select –right click- open in new tab.
Another important factor for creating backlinks is that to bring down your Alexa ranking below 10 lakhs. When your website or blog ranking goes down below 10 lakhs i.e. say 9 lakhs then there are many websites which shows alexa ranking on their websites so once it happens you will get automatically 10-15 backlinks for your website. You can check those on Alexa backlink reputation field.
