I stated "post for noobs" so all the "big guys" don't get upset with me. Lol. This is nothing groundbreaking, but AdSense Noobies need to be well aware of this. Make sure your AdSense ads are relevant to the content you're providing. I recently had one of my sites displaying Ads that had nothing to do with the site's content. With that said, it didn't matter how well I had my ads placed because the ads weren't related. I made a few fixes and just like that, my earnings greatly increased. Some of the fixes include 1) Increase CTR Niche Blogging If you're blogging on a niche, the AdSense advertisements that appear are that much more likely to be relevant than if you're not. With that being said, try to stick to a specific topic on your blog. The more specific your topic is, the more clicks you'll end up receiving. 2) Section Targeting There is special AdSense coding that allows you to tell the AdSense bot what words you'd like it to target the most and what words you'd like to ignore the most. 3) Placement AdSense ad placement is also very important. If you have an ad at the bottom of your page that is more relevant than the ad at the top of your page, you may want to place the ad at the top of your page in your left sidebar, then the ad at the bottom of your page to the top of the page. This will place your most relevant ads in the place that gets you the highest CTR. These tips should definitely help you increase your AdSense earnings. You can view this full article at my site. By following this information, I increased my earnings and clicks overnight.
You can also use the ads filtering and review center to your advantage as well to ensure that no unwanted ads appear.
