I need some review for my blog. I am looking to put a link unit, but not sure where i can put it. This is my blog: http://www.greentacblog.com
Well its always good to have ads placed above the page scroll, so you hit that right. eventhough I dont like you placing such a big ad there inside the blog posts, its annoying for your readers, I think you will have just as many clicks with a smaller ad. and you will have more happy and returning visitors.
You can place link ads at the top and bottom of your post along with your existing block ads. You can also place small link and Skyscraper ads in your sidebar. Inside AdSense blog mentioned that AdSense publishers could no longer place ads directly under Headlines or Titles. To go around that, you have to add a simple text saying 'Ads' or 'Sponsors' at the top of your ads. Everything else looks okay. You did a good job in blending-in your ads with your content.
