HOW TO INCREASE ADSENSE EARNINGS?

Here are some things to consider:  
1.Choose one topic per page. It is best to write a content for your page with just a few
targeted phrases. The search engine will then serve ads that are more relevant which will
then result in higher click throughs. 
 
2.Using white space around your ad. This can make your ad stand out from the rest of
your page so visitors can spot them easily. There are also other choices of colors you can
use, provided by search engines, which can harmonize the color of your ad with the web
page color. 
3.Test your ad placement. It is recommended to use the vertical format that runs down
the side of the web page to get more positive results. You can also try both horizontal and
vertical formats for a certain period of time to see which one will give you better results.  
4.More content-based pages. Widen the theme of your website by creating pages that
focus more on your keyword phrases. This will optimize the pages for the search engines. It
can not only attract traffic but also make them more relevant for the AdWords to be
displayed.
