If Adsense is running on your site or blog,ill tell you a few tips to increase the income with just 5 easy steps,taking no more than 10 minutes of your time:
1.Change your link colour to blue. While I cannot disclose my CTR I can tell you that this one little change more than doubled my CTR. I know that there are others out there who advocate that your link colour should be the same as the other links on your site, but try it out for yourself for a day or two. I think you will be highly surprised!
2.Set the URL colour to the same colour as the ad's text. This makes the URL ''melt" in and makes the link colour stand out more, definitely making it more "clickable".
3.Decrease the number of Adsense blocks that you are displaying on a page. I don't know how others have experienced this, but my income seemed to be less if I had more than one block of Adsense ads displayed at once - and your CTR is definitely less if you have more than
4.My suggestion would be to have one Adsense block in your content, and an Adlinks block somewhere at the top of your page. Adlinks is great because if someone clicks on a link in it, they are taken to a page with many more choices on it, which increases your chances of them clicking through.
5.Write Content Around High Paying Keywords
Now write articles or even create new niche websites around the high paying keywords you identified in the previous step. Be sure to include the relevant keywords in the page title and in headers so the AdSense bot gets the context right and displays ads for which people are bidding high. Putting emphasis (bold & italics) on the keywords near the ads helps too.
