I have a very old website with insanely large files that I can not figure out the best way to increase the adsense CTR. The design is extremely simple, it's basically all formatted text with just a background image, and a little navigation menu up top, along with an adsense banner. I tried placing a CSS fixed header adsense banner on the page (so even when they scroll they still see the adsense ad), and this actually seems to have worsened my CTR. Cliffs: -Large pages with no real design -Require lot of scrolling -Pathetically low CTR, even when ad remains on the screen 100% of the time. Anyone ever dealt with a situation like this? What has worked best for you?
