Make Money: Adsense
Go wide and get rich (media)
If you’ve just recently started with AdSense, there are two format-related tips I would instantly recommend. The first is to enable both text and image ads, which will increase competition among ads to appear in your ad units and may result in higher CPMs. Second, use some of our wider units, such as the 160×600 wide skyscraper, the 300×250 medium rectangle, or the 728×90 leaderboard. There are more rich media (image, flash, video and gadget) ads available in wider ad formats, and wider ad units are the preferred formats for advertisers looking to target your site. Again, increased competition or your ad space will help you maximise your earnings potential.
Use channels
Channels are powerful reporting tools, sometimes overlooked by new publishers. They allow you to view the AdSense performance of a site, a specific page, or even a specific ad unit, which can help you see where your ads are performing best. You can name these channels, give them descriptions, and then define them as ad placements so that they are visible to AdWords advertisers.
The most important thing is that choose the color of the ads links and title to match your website!
