Increase your profits with Adsense link units
If you use Adsense then you should consider using Adsense link units. I always used to be against them, I didn’t have any real reason to, I just didn’t. I guess I thought they would reduce my eCPM and CTR because it would take visitors away from my main adblocks. Also for you to actually earn off a link unit the visitor needs to click the link unit, and then click again onto one of the ads shown. This seemed to me like too much work for the visitor who I thought would just give up.
One day though my friend told me he started using it and gained an extra $1 eCPM, which if you get a lot of visitors, is a pretty decent return. The trick is to blend them into your site so that they appear as normal links. For example if you have side navigation, place them there in a vertical unit or you can place them horizontally above your content.
Ideally what you need to do is test, if your site is established I would suggest noting down your current earnings, eCPM and CTR for a week, and how many visitors you got. Then trial the link units in the two locations I mentioned, or any more you can think of. Do each test for a week then see what gets you the best return. It may not work for all sites but I have seriously seen a good return on it.
The key thing is… test test test, and dont be afraid to try new things! If my friend hadn’t I would have been earning a few less dollars a day!

I never thought about using the link units. I will try them on my forum.
Yeah they really work! You just have to get the placement right. Look how DP uses them, I guess they are pretty well optimised for a forum.
