How to Improve Your Adsense Revenue (RPM)?

So, is there a way to improve your RPM? The answer is yes and no. You really do not want to become over-infatuated with trying to raise your number. You need to be more concerned with providing quality content on a consistent basis. However, according to the Adsense Rep there are a few things that you can do.

Opt-in to Both Text and Image Ads

Text ads just display links and text like traditional classified advertisements. Image ads will display graphic advertisements more like you would see on a traditional billboard. In your Adsense account you can choose to display one or the other on your site or both.
According to the Adsense Rep, displaying both is your better option. This creates more competition because it pulls in more advertisers competing for the same space. Google Adsense will then display the higher performing ad.
Also, you open up a new income source with image ads. Some image ads pay out income by impressions. That means you get paid even if no one clicks on the advertisement. Of course, you need to test out for yourself whether opting in to display both is the best way for you to go.

Choose the Most Popular Ad Blocks

Another way to supposedly raise your Adsense Revenue is to use the most common adsense blocks. Some advertisers only design graphics to be displayed using certain ad sizes. It does make sense that using the ads that have more advertiser competition could lead to higher revenue for you. Again, test this out to see if it is true for you and your niche.
Some of the more popular ad sizes mentioned were:

• Leaderboard (728×90)
• Large Rectangle (336×280)
• Medium Rectangle (300×250)
• Wide Skyscraper (160×600)
