Most webmasters don’t think about AdSense as an SEO tool, but it can be. Once you’ve established your website’s keyword focus and you’ve built enough pages to run your test, place a test ad or two on a couple of pages and let them sit for a week. Go back and take a look at your ads at various times of the day to see if they “match up” with your website’s content. If they don’t then it could be that you are not using the right keywords for your website.
To make this work, you have to sign up for AdSense and set it up for the right keywords. Make sure that your are AdSense ads target the right keywords because if they don’t then you’ll be running the wrong test and you won’t have any accuracy. The test works best on information publishing websites, but it can be done on just about any type of website. If you plan to use it as a test on your service-oriented website, don’t leave the ads up for too long because you’ll send your customers off to other places on the web and they’ll never do business with you again.
Remember, when you set up your AdSense, configure it to optimize with your content. You can opt to allow any type of ad to run on your site, but that won’t help you optimize your site for the type of visitors that you want. After you have determined whether your site is optimized properly, you can take your AdSense ads down and move on to the next project.
