If after running Adsense on your site or blog for quite some time you feel that you are not making as much cash as you could, in most cases you are right. Many of us feel frustrated that we are not generating enough revenue that we expect to do and this is all down to traffic levels as well as Click Through Rates (CTR).
Here are some of the ways you can turn traffic into Adsense traffic:
The first and the foremost thing that you need to do is tune up your site's contents. While for some people this isn't an option (for e.g., if you are running a forum it can be a lot harder), most people can make their websites veritable cash cows. Good content creates royal readers who very often returns for more.
To begin with, you should find out and analize what your site's keywords are. This is a very basic technique in SEO (Search Engine Optimization) also known as keyword density verification. You can use SEO Density Analizer to do this job.
You should then take this list of words and search the Overture Search Inventory or Google AdWords Sandbox to find out what other words could be doing better then what you currently have.
From that point on try to keep your site focused on the things that appear mostly in the keyword suggestions you receive. Try to include those keywords, or at least some related keywords as often as you can in the links on your site.
Because of the way Google AdSense works this is a sure way to increase your earnings because you'll get better ads in your AdSense banners, similar to how you would get a better Google Page Rank
Try to add new pages to your site as often as you can. This is very important because the more pages you have, the higher the chance that you will get more hits on your ads.
Choosing appropriate Adsense ad formats and placing them at the best location is also very important. Generally the top three Adsense ad formats are: 336x280 large rectangle 300x250 medium rectangle and 160x600 skyscraper.
Make sure you blend the ads by choosing the appropriate colors, as making them different from your site's content is sure to make visitors regard them as banners which are irrelevant to the site itself.
Position your ads where they will generate the highest amount of revenue is a must. Generally the location is said to be right if it is at the beginning of your site's actual content, i.e., above the fold.
On pages with a long text body, you might find 160x600 skyscrapers to do better, simply because users get exposed to them for more time. Also, for sites with news or similar items, you might find a good position to be at the bottom of your content, because that's when people are finished reading your story and are looking for something else to do.
You should use more AdSense units if you have a lot of text on your pages, but remember not to overdo it because you might find that you will get a lot lower CTR and lower revenues then you were getting in the first place by employing this technique inappropriately. You can add as many as three similar ad units, so use them wisely.
Use the Google AdSense Preview Tool and analyze what ads would get served on your page as it be a very handy testing mechanism.
Just make sure you respect the AdSense policy regarding click fraud. As a pointer you could place a picture next to your adds, just make sure to leave some room in between in order to make sure this isn't regarded as encouraging visitors to click the link.
Of course there are more ways to increase AdSense traffic from your site, but these should serve as a good starting point for income maximization.
