Small but still good. I never knew this would work but I guess it is working. I have a screenshots section where the screenshot is in thumbnail view which is hyperlinked to a popup window that redirects to that screenshot's image file. Example: .jpg or .gif, etc. I have changed it so it launches a popup window that contains a Previous, Next link, along with the screenshot in full size, as well is a large Adsense banner on the bottom. This gave me about 1 or 2 more clicks per day. Anyone thinks I should change more for better outcome? My website is in my signature.
But it is user activated. A gallery of thumbnail screenshots. Each thumbnail launches a new window that shows the screenshot, a previous and next button along with the ad.
What signature? Also as jackburton2006 said, it is against Google AdSense Program Policies... If you're unsure, you can always send Google an e-mail and ask.
You didn't remove it, you just don't have the privilege of using signatures yet until you've achieved a certain number of posts.
