Visiting and leaving comments help get traffic

As you can see, I have a counter on every blog I have. Although the visits I get daily aren't much to speak of yet, I know that there are people who come and visit this blog when the number on the counter changes. But what is strange to me though is the fact that those who visit never take the opportunity of "pushing their product" by leaving a comment and at the end, their url. It's a golden opportunity for traffic wasted.

We are all aware that we new bloggers share the same problem--increasing traffic. Yet, we do not take this opportunity of leaving a comment and our url along with it. I notice this in all my four blogs. I know that there are visitors but they just look around and go.

It does not cost you a penny to leave a comment plus a link. You only increase your chance of gaining traffic by being more visible.
