hi I want to make better rank of my site.I have found many blogs on www.blogspot.com that relate to my site.I want to insert my link on thier blogposts when I comment there. my question is inserting one time on one blogpost is enough or it is better to insert more blogs and more blogposts on blogspot.com .I don`t mean the blogs that have thier own domains... I mean blogs on blogspot such as www.xxx.blogspot.com
