The simple answer is: is an advertising placement service by Google.
A slightly longer answer is: Adsense is Google driven advertising designed for website publishers who want to display targeted text, video or image advertisements on your site. Earn money when site visitors view or click the ads.
Adsense is a free and simple way for website publishers (bloggers such as us) of all sizes to earn money displaying ads on their website.
This means no managing advertiser relationships.
Google deals with the advertisers. The different rate of pay-per-click depends on The more competitive the search term, the more the advertisers pay and the more you earn as a publisher.
You still have some control over the placement and size of the ads, and the ability to block certain categories of ads or even specific advertisers.
Once you are accepted to use Adsense ads on your site and have installed an ad code on your site, Google bots check out your site and match up the ads to the keywords on your site.
There are two ways to make money from AdSense:
- Impressions – this is based on the number of pageviews of pages or posts with ads
- Clicks – this is based on how many people click on the ads (don’t EVER click your own – more on this later)
Once you get to a minimum threshold of $100, Google will either send you a paper check or make a direct deposit into your bank account.
You don’t have to be a big blogger to have Adsense, have it from the beginning and, even if you are only making pennies a day, or a week, you’re still making more than if you don’t have them on your site.
