AdSense allows website publishers to display contextually relevant advertisements on their website. If a web visitor "clicks" on an advertisement, the web publisher will earn a percentage of the advertising revenue generated as a result of the click. Many webmasters have built content websites 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.

Top AdSense Tips:

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 sites focus, consider how much the advertisers pay for the advertisements. If the site is focused on ringtones, like Ringtone Central http://www.ringtones-central.com the payout per click is going to be very small, as 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, it is usually 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 website that is optimized for the terms that have the highest payout. Consider targeting terms that are moderately priced.

3. Aged Sites / Time.

Over time as a website is spidered by Google, advertisements will generally increase in relevance. In general, older websites will rank better in search engines. The closer the advertisements relate to the webpage's content; the higher the "click-through" the publishers will see.

4. Coding.

In order to minimize a websites maintenance place the Google generated AdSense code in the website template or an include file. This will allow you to easily experiment with different advertisement sizes and ad placement, and keep the web maintenance to a minimum.

5. Tracking Channels.

In order to know how effective a specific website or ad placement is use distinct channels and subchannels within Google. This will allow you to discern what performs best on a specific website. Using channels will tell you what sites are making money, what advertisements are making money and what ad position is the most profitable on a specific website. Keep in mind that you should run an advertisement for a full week, in order to properly test its effectiveness, different days of the week will vary the web traffic so comparing one week to another will give the most accurate reflection of how effective a campaign performs.

When testing different advertisement sizes, placement or color schemes be sure to leave campaigns in place for one week, different days will often result in web traffic fluctuations. Comparing web traffic, week to week will give a clear indication of what ad formats perform the best.

6. Integrated Ad Placement.

Many webmasters have been successful at integrating advertisements into a website. The easiest way to integrate an advertisement into a website is to remove the advertisement border. This will allow the ads to better blend with the webpage. Google recommends contrasting the link colors with the website 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.

example of integrated ad placement: http://www.golf-clubhouse.net or http://www.security-protection.net

7. 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.

8. 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.

9. 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.
