The most important step is to choose the right keywords for your web pages. These will influence both who visits your site, and how AdSense assigns ads to you.

The number one mistake most website publishers make is to constantly choose high-paying (i.e. expensive!) keywords assuming that it will yield them more income. While it is tempting to choose such keywords to get higher rankings on search engines, be prudent when it comes to selecting the right keywords that go with the AdSense ads that are to be displayed

Just because a keyword is high paying and is seemingly related, does not mean it is totally relevant and you need something relevant. Relevance is more important than value!

To make money with Google Adsense it all starts by choosing high paying Google Adsense keywords to make more money. Look for keywords that are searched for frequently, but have little competition and build web pages around these keywords. Your pages will still display the high paying Adsense ads to make you more money.

Your clickthrough rate will be boosted tremendously by including the right keywords in your web copy, of course. Keywords occurring in your ads are usually highlighted on the search engine results page. This also helps in drawing additional attention to your ad.

The URL of your webpage is also an integral part of achieving success on Google AdSense program, as it is on the Web generally. Current wisdom holds that the keywords in the URL are equally if not more important than the ones featured in the actual webpage content or in metatags. If you change your ordinary URL to a keyword rich URL relevant to your market, it is possible to raise your CTR

Obvious domain names with the keywords that you want might be expensive to purchase from a broker, but you can also buy used domain names that are no longer active, often for just a few dollars per year
