One of the best secrets that I've learned about AdSense is that you can get a lot of revenue if you place AdSense in your links pages. Almost everybody now has a links page or collection of links on their website for other resources. If you have a categorized links directory or a few links pages grouped together this is even better. What AdSense can then do is determine exactly which ads to show on which page.

Since you're already going to be losing traffic from those links anyway, why not get paid to actually drive people to other websites! That's one of the key secrets: include AdSense on your links pages.

Another great secret is to use your newsletter or mailing list to generate AdSense revenue. They don't allow you to send anything out by email that includes AdSense, but what you can do is you can create a newsletter that is online. You would send an email and, rather than including the newsletter within that email, you would send people to a link. People will land on that link and it includes your newsletter in html format along with relevant AdSense ads.

This also builds up over time. You can have multiple issues of the newsletter back-dated, all of which are accessible and being read by your visitors and all that include AdSense ads. This is a great way, and a very quick way, to monetize your newsletter. If you create a newsletter around a specific theme every single time you email it out, you'll start to see that the ads become relevant each time and you'll get more and more people clicking on them.

Another secret for AdSense is to create the text ads with the same background as your sites page. If you do this they blend into your site much more effectively. If you use frameless ads, where the color of the frame is the same as your website, this will work even better.

The main secret that I found in creating an AdSense empire is to do one thing every day which will actually improve your AdSense earnings. Whether that's add more content, get more key phrases, send another newsletter or read more information about AdSense; do one thing each day which earns you more!
