What's your opinion

Honestly i don't really know how to catch the readers attention, why bloggers stick to some blogs whilst the other doesn't read even the article of some newbie bloggers, some say its the credibility of a blogger who writes the blog and some will say well its all depends on your article the more bloggers can get an ideas on your blog the more readers you can make, the other may say its all depends on how are you going to promote your blogs,i am thinking on how about if one blogger can do all that we mention here is it the right basis to gain more readers on our blogs? whats your opinion on this?
