Adsense Blacklist URL’s :

There are many advertiserss which pay very little per click. There used to be a site showing the Adsense ad “black list”, but if you have compiled a list of your own or you know of any site with very poor performance, you can block that advertiser’s URL. I have done it myself, and it improved my revenue by 10% in one week’s time. You can also block your competitor’s ads from displaying on your site

Ads between posts:

If you want to increase Adsense revenue, you can easily configure Adsense ads to match with your page background and colors, and add 468*60 image ads or text link ads in between posts.  You can also add 7-10 pictures, keeping in mind that you want to offer a good user experience to your readers. Make sure to add enough space between ads & content, so that it doesn’t violate AdSense policies.

Adsense for Search: Add extra revenue source

Adsense offers many ways to monetize your site, and you should try to take advantage of all ad types. Adsense for Search not only helps you monetize, but it also helps with user navigation. I have previously shared a guide on setting up Adsense for Search.

Organic Traffic /U.S :

Adsense ads perform best when your traffic is from search engines.Also, interest-based ads might not perform as well if you are getting more direct traffic. Many people complain about low CPC and low Adsense income despite leaving millions of impressions per month. This is mostly due to CPC and traffic sources. Start targeting traffic from countries like the U.S.A and the U.K, and you will end up getting high CPC.

Use Better Keywords

EffectiveKEYWORDS are the bread and butter of Google Adsense earnings. If you’re using highly competitive keywords you’re not going to rank as well as if you were using lower competitive keywords. The Google AdWords keyword planner is a great tool for finding low competition keywords for your articles and blog posts.

I tested with Different Colors and Fonts

If you enabled both image and text ads on your units you should be able to customize the colors and fonts. I did some testing with both of these factors, and it helped to increase the numbers. Nothing dramatic, but it was definitely worth my time.

You just need to track your CTR for a couple of weeks. Then change the color or font and track it for another week, seeing if you can beat the original CTR. If you can, keep the new format. If you the performance decreased, try a new color or font and track the CTR for another week, until you find the optimal combination.

On my sites the best results came from making the ad units merge with the look of the site, but on some sites contrasting colors perform better, so testing is a must.

I played around with section targeting

Section targeting is an AdSense feature that allows you to suggest specific sections of your site that should be used when matching ads. You can read more about it here.

I found that on niche and small websites section targeting can help a lot. Often times Google was displaying unrelated ads on these sites because there weren’t enough pages. After using section targeting I managed to increase the relevancy of the ads and consequently the CTRs.
