Google AdSense is an advertising program that was launched in the middle of 2003 by Google, the popular search engine. Google acts as an intermediary between a vast number of advertisers and an equally impressive number of website owners.

It offers a quicker & flexible way to insert Adsense or any Ads code into a blog post. Besides, it can randomly place the Ads anywhere within a post. It comes with a simple setting page, and it does not overwhelm you with complicated customizable options.

How Adsense work:

• The webmaster inserts the AdSense JavaScript code into a webpage
• Each time this page is visited, the JavaScript code uses inlined JavaScript Object Notation to display content fetched from Google's servers
• For contextual advertisements, Google's servers use a cache of the page to determine a set of high-value keywords. If keywords have been cached already, advertisements are served for those keywords based on the AdWords bidding system
• For site-targeted advertisements, the advertiser chooses the page(s) on which to display advertisements, and pays based on cost per mille (CPM), or the price advertisers choose to pay for every thousand advertisements displayed
• Search advertisements are added to the list of results after the visitor performs a search
• Because the JavaScript is sent to the Web browser when the page is requested, it is possible for other website owners to copy the JavaScript code into their own webpages. To protect against this type of fraud, AdSense customers can specify the pages on which advertisements should be shown. AdSense then ignores clicks from pages other than those specified
