Adsense is something with which some website owners have had smashing success, others very little. Website owners who have done well with Adsense and are seeing good revenues are those who have become adept at tracking the performance of their campaign and use this information to fine tune their campaigns to increase click through rates. Tracking and testing is what Adsense is meant for and should be used to maximize your advertising campaign's potential. The first step here is to track clicks to determine how your ads are performing for you. The Adsense tracker (it's free!) lets you get detailed information about the clicks your ad has received. This information displays in your stats as soon as the necessary javascript has been placed on your site. You should keep an eye on your statistics and evaluate how each is doing for you on each page. Some pages will no doubt do better than others - try to figure out what the common element is to your highest performing pages. The content, graphics and keywords are all factors in the performance of your webpages. Use these winning elements and track your stats to find out if these changes have worked for you. Adsense offers advertisers a lot of options for their ads. Nearly everything about the ad can be changed, including size, shape and color, which can also increase your click through rate. If you are still not doing well after making changes here, it may be time to back to the drawing board and make all new ads. The ads which will do the best for the web are ads which mesh well with the rest of the page, e.g. the content. Make your ads fit in with the look of your site; you can test these designs with Adsense by watching your statistics. Search engine optimization is another element which Adsense tracking and testing can help with. Your keywords and their ranking matter. Competition is also something to watch out for - if there are a lot of competitors out there using the same keywords then these popular keywords may not be the best investment for you in terms of traffic. Using niche keywords may be a better idea; these are keywords which are popular, yet not used by everyone out there. These words also are more tightly focused on a market which helps you stand out from the competition and attract customers who are more likely to make a purchase. You can also see higher profits from Adsense by using niche keywords than with more popular keywords. You can find free tools, as well as paid services which can help you find niche keywords which will work for your site. Whichever way you choose your words to begin with, use Adsense to watch your statistics for views and clicks to see which bring in the most results for your site. Tracking your statistics is the key to success with Adsense.
