Google AdWords

Google Adwords is a way for you to advertise your site.
Registration is comprehensive and is not something you
should rush through. They will allow you to pick keywords
and key phrases and set the price you’re willing to pay per
click. Unlike other sites that are mere ad banks, Google
AdWords allows you to target your audience in the same
way they do with AdSense. Your ad will only appear on
search pages and websites related to your site, using the
keywords and key phrases you’ve chosen. The higher your
click-thru rate and click-thru price is, the higher you’ll rank
in their ads.
The screen shot below shows an example of Google
AdWords. The sponsored links on the right of the page are
paid for by websites and Webmasters through AdWords. Of
course, in this instance, one of the keywords they used was
‘google.’ The Webmaster will pay a set amount per click for
each visitor that clicks through the ad below to his/her site.
