A lot of people probably just stick their adsense on their website and hope to make some money. A lot of people don’t even realize that one simple change here and there can drastically increase the amount of money you make with Adsense. Here are five ways you can increase your adsense earnings, and you probably aren’t doing any of them.
1) Rotating Color Schemes – Rotating color schemes is one way to reduce “ad blindness” which has plagued a lot of internet users. Basically, internet users are no longer even seeing ads, especially not traditional ad sizes like 728×90. Due to this, publishers need to do whatever possible to reduce ad blindness. One of the ways you can do this is to create rotating color schemes. To do this all you need to do is go into Adsense, click on manage ads, and use multiple color schemes and Google will automatically rotate the colors for you.

2) Rotating Ad Placements – Again this is done to reduce ad blindness. You can increase your CTR by making your ad appear in different areas. Of course this is difficult to achieve if you’re using WordPress, but for my custom-coded CMS I was able to randomly place ads all over my content. The result was higher CTR.
3) Experimenting with new sizes and formats with channels – Experiment experiment experiment! You must be always checking out new placements, new colors, new sizes, etc, and testing all of this with channels. So basically you do this. When you start a new experiment you make a new ad on adsense and also a new CHANNEL. Compare each channel’s revenue and then choose to show the channels making the most revenue.
4) Using an ad-friendly design - Sometimes the design is something that matters. One main thing that is important is that the ad looks good with the design, meaning it blends in nicely with the surrounding page. Actually I made a huge mistake on my website, AmpedAsia.com for the latest version 4. I widened my content area. What happened was after I widened the content area the best ad size (336×280) was no longer the best ad size. The CTR plummeted, and I’m not 100% sure why, but it did. I then experimented more and realized that the 728×90 ad size was the best fit for my design.
My tip to you is to optimize your page for the 336×280 ad size because this is the ad size with the highest CTR in MOST cases. So that means your content area shouldn’t be much wider than about 400 px.
5) Choosing adsense-friendly niches – This is something that I definitely did not do! Choose a niche with high competition so you’re going to get high paying clicks on your ads. A good general rule of thumb is that if the industry you’re targeting is expensive offline, then it’s also expensive online. For example, real estate and travel.
