- Location, location, location. Position your AdSense ads at the top of your page or near the focal point of your pages

- Offer freebies or unique content. Free stuff is a big draw to visitors and more visitors equal more click throughs, which turns into more money in your wallet

- Rotate content often and let your visitors know it's always changing. It keeps them coming back for more.

- Keep those email addresses. It's important to keep the email addresses of your visitors and let them know when your content has changed. Consider offering a free newsletter or ezine to your visitors to stay in contact with them.

- Add Google search to your site. In addition to offering visitors the convenience of searching on your site, you can make more money from Google by adding this feature.

- Keep your graphics small and simple. Because graphics and animations take longer to load than text and links, the simpler your pages, the quicker they load. And the faster they load, the faster your visitors can click their way to your profit.

- Keep the design simple and clear.

Reporting and monitoring is the next important step. Google has built in reporting features but you may want more detailed reports as well. The Google reports will show:

- Total number of page impressions

- Number of ad clicks and the click through rate

- The cost per click (CPC) and cost per 1000 impressions (CPM)

- Total earnings

While this is wonderful, valuable information, you may also want to know:

- Click through rates of every page on every domain you are using AdSense on (the Google tool called “Channels” limits the information you get from each domain or ad type)

- Keyword reports if you have the Google Search feature on your site(s), so you can optimize for those search words

- Reporting in real time, rather than waiting 48 hours for reporting from Google

- Which particular ads are making you money

- Detailed information about each click including IP address, date/time, page the ad was on, particular ad that was clicked on, original referrer to your site

You can get all of this from third party AdSense tracking software, available online from a number of vendors. You may want to email Google to make sure it's an approved script; otherwise you risk being removed from the AdSense program.

Once you have the data regarding which ads are working and which aren't, change your preferences to stop running ads that aren't paying off and increase the ads that are. There are options to change color palettes of the ads to better fit your site, a variety of ad formats to always keep your website looking fresh and don't be afraid to rearrange content often.
