This thread is basically about things you must avoid :P
Too many ads
If your page is plastered with more ads than a Formula 1 car then donít expect your readers to stick around for very long. I am not saying don't have ads but please do not over monetize. Keeping a reader is much more important than earning a penny from an accidental click.
This is something most people are guilty of from time to time (my sites included). You should spend as much time editing your article as you did writing it.
Never reply to comments
As I have said before, every comment raises the value of your blog, your readers actually take out time to comment. The least you can do is to say a small thank you. If your readers have a different point of view then donít come down on them too hard.
Anything else that turns readers off?
