AdSense is a contextual advertising program for which publishers simply have to add a piece of code to their sites that helps Google analyze what your page is about so they can serve Ads on that topic. This increases the chance of your visitors clicking the Ad which increases the chances that you will earn from them. AdSense is a quick and easy way for bloggers of all sizes to display Ads that are relevant to their content.

AdSense also allows you to earn money by using Google Search on your site that will display relevant Ads when visitors search on your site. AdSense also has a referral program that allows you to earn by recommending various products like Firefox toolbar, AdSense, Adwords, etc.

When a publisher who signed up for Google AdSense through your referral earns $5.00 within 180 days of sign-up, you will be credited with $5.00. When that same publisher earns $100.00 within 180 days of sign-up and is eligible for payout, you will be credited with an additional $250.00. If, in any 180 day period, you refer 25 publishers who each earn more than $100.00 and are all eligible for payout, you will be awarded a $2,000.00 bonus!

I have been a full time blogger now for more than a year and it was with the help of AdSense that let me earn through blogging. I use many revenue sources but AdSense is my biggest money maker. I highly recommend AdSense as a way of monetizing a site, especially for those just starting out.
