Google AdSense allows Web site publishers/blogger to display contextually relevant advertisements on their website/blog. If a Web visitor “clicks” on an advertisement, the Web publisher/blogger will earn a percentage of the advertising revenue generated as a result of the click. Many webmasters have built content Web sites around the  Google AdSense model. In many cases the specific intent of the webmaster is to profit from Google AdSense. Other webmasters use Google AdSense to supplement their revenue. Regardless of the webmaster’s intent, the following tips will help webmasters looking to profit from AdSense.

1) Niche Sites
Targeted niche sites that have a clear theme, tend to generate more advertising revenue simply because it is easier to achieve decent  search engine placement.. Be warned though, you want to chose a niche where there is a sufficient number of advertisements available.

2) Target Keywords
When determining the site’s focus, consider how much the advertisers pay for the advertisements. If the site is focused on ringtones, the payout per click is going to be very small. Because ringtones are not high ticket items, advertisers will not spend a lot on pay-per-click advertisements.

With less obvious markets, use Overture to determine how much advertisers pay per keyword. The cost will usually be similar on Google. Search Overture for a keyword then click “View Advertisers’ Max Bids” in the top right corner. This will show the Overture inventory and how much is paid per keyword. Because the market has become very competitive, it will be difficult to rank well in search engines with a new Web site that is optimized for the terms that have the highest payout. Consider targeting terms that are moderately priced

3) Integrated Ad Placement
Many webmasters have been successful at integrating advertisements into a Web site. The easiest way to integrate an advertisement into a Web site is to remove the advertisement border. This will allow the ads to better blend with the Web page. Google recommends contrasting the link colors with the Web site colors to increase click-throughs. It is also suggested that webmasters randomize the color of the advertisements, so that frequent users will not naturally “filter” the ads.

4) Number vs Value of Advertisements
Up to three advertisements can be listed on each page. This decreases the value of the advertisements served, so publishers should cautiously add advertisement units, as it dilutes ad inventory. In other words you want to serve the most expensive ads at all times.

5) Hot Spots
Like Web copy, “above the fold” holds true with AdSense as well. This means that advertisements that appear without having to scroll will be read more frequently. Hot Spots are areas on a Web page that result in a higher percentage of click-throughs. According to Google, the highest paying advertisements are located on the hot spots.Google does not indicate if image advertisements or text ads perform better, so webmasters are encouraged to experiment with both.

6) Highest performing Ad Sizes
According to Google the 336 x 280 rectangle, the 300 x250 rectangle and the 160 x 600 sky scraper result in the highest number of click-throughs. Depending on the website’s design and layout, publishers may experience different results with different ad sizes, placements and color schemes. Expirement and track the results for each website to maximize the AdSense payout.
