General Adsense Tips (in no particular order)
     -Never label your ads as anything other than "sponsors" or "adverisements."  Anything else, like "helpful links," will most likely get you banned from the program.
     -Don't show popups on the same page as Adsense.
     -Never tell anyone to click on your ads.
     -Stay away from huge skyscraper ads, they sometimes tend to annoy the visitor.
     -If you're not using images next to the ad, use image ads.
     -Use a descriptive title, site description, and keywords to get better target ads.
     -If you're not using image ads, use images next to the ads.
     -Never, ever, use borders.
     -Always coordinate the colors of the ad with the color of your site.
