What is AdSense

AdSense is a service provided by Google to provide advertisements to Websites.

Google allows Web masters to join the AdSense program to enable text, image, and video advertisements on their websites, in return for financial compensation.

The advertisements are facilitated directly by Google and generate revenue for the site owner on either a per-click or per-impression basis.

How AdSense Works?

  • Google Provides the webmaster with a small piece of JavaScript code which gets inserted into their webpage.
  • Each time the webpage is visited, the Java Script fetches an appropriate advert and displays it on the screen.
  • AdSense can provide contextual advertisements, which makes sure that the Advertisement is appropriate for the Webpages topic. To provide contextual advertisements Goole keeps a cached version of the page on their servers to work out a set of keywords.
  • AdSense can provide site-targeted advertisements, which is where an advertiser chooses a specific page to display adverts.
  • Page views of AdSense advertisements are irrelevant in terms of generating revenue - commissions are only generated when visitors to the webpage actually click on the ads themselves.
  • Goole can provide Webmasters with Java Script to provide a targeted Search Facility to a Web Page. Search Results from these Search boxes also provide a list of paid advertisements, which when clicked provides income for the webmaster.    
  • To avoid JavaScript being copied fraudulently, AdSense advertisers can specify the pages on which advertisements should be shown. AdSense then ignores clicks from pages other than those specified.
  • Advertisers pay Google an agreed amount every time one of their ads are clicked. Google keeps a percentage of this amount and passes the rest to the owner of the website itself.
  • When a certain earnings fresh hold has been reached the website owner will receive payment from Google.
  • To make AdSense Management extremely easy Blog Owners also have the option of using one of many third party AdSense plugins.

The relevancy of ads placed by AdSense  is based on all sorts of criteria, but Google’s algorithms are superb and  ads are normally very relevant to the web page on which the ad is displayed.

Google AdSense has become important to many webmasters, as is allows relatively small Websites and Blogs, which may be ignored by traditional advertising companies, to add income streams onto their site, providing a way to recoup some of the costs associated with creating and maintaining websites on the internet. With Google AdSense, many webmasters can even make a profit using Google AdSense.
