If you have a new website and using Google Adsense on it but not seeing any significant revenue increase, I have a simple tip for you. Whenever you create or edit your ad code, just make sure the type of adcode selected is text only. And then check for next few days. If your site has good quality content, you will definitely see a increase of revenue by making this simple change.
Logic behind this
Actual Logic behind this is that most of people nowadays use Adblockers and have a thorough knowledge of how the Internet works. Most people just keep getting offended with Huge image banners aligned with text. It distracts them completely from the quality content.
Result is that neither they seem to be interested in your content and neither in your website. And eventually they leave your site without seeing the content and the ad!
Now when you keep the ads as text only, text ads not only compliment the content but prove to be a valuable addon with the text. So people read the text and even takes interest in value added content too.
Use Text ads only for all ads which are close to main content. More revenue increase will follow.
Have you ever seen Google showing image ads on their search results, orkut or gmail?? Now you know the reason!
