Concentrate first on your posts rather than your adsense ads

If you are just starting with your blog do not concern yourself much with the adsense ads.

Put more thought in your posts, because the posts are the one that will invite in readers to your blogs.  Do not be afraid to go back in your other posts, reread it and if you see something wrong edit it, if you want to add additional points go for it.  There is always a room for improvements.

One tip I have when posting is make your topic relevant.  As I have emphasized in several occasions, make sure that when your visitors are finish reading your post they should have learned something from it, and that learning should not be that they would not want to read another of your articles.

Back to the point I am making, write quality first then quantity second posts, and when you see that they are coming in - your visitors, that your blog's traffic is increasing, then you could think of making something out of those adsense ads.

-access out, God speed!
