Know About Google AdWords :

Google AdWords is google's main advertising product and main source of revenue. Google's total advertising revenues were USD$28 billion in 2010.AdWords offers (PPC) advertising, cost-per-thousand (CPM) advertising, and site-targeted advertising for text, banner, and rich-media ads. The AdWords program includes local, national, and international distribution. Google's text advertisements are short, consisting of one headline consisting of 25 characters and two additional text lines consisting of 35 characters each. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.

The original idea was invented by Bill Gross of Idealab who, in turn, borrowed the idea from the model of the Yellow Pages. Google wanted to buy the idea but a deal could not be reached. Not wanting to give up on this form of advertisement, the company launched its own solution, AdWords in 2000. AdWords followed a model that was significantly similar to Bill Gross' creation which led to legal action between the two parties. Eventually the dispute was settled out of court.

At first AdWords advertisers would pay a monthly amount, and Google would then set up and manage their campaign. To accommodate small businesses and those who wanted to manage their own campaigns, Google soon introduced the AdWords self-service portal. Starting in 2005 Google provided a campaign management service called Jumpstart. Google's Jumpstart program offers free telephone support from a Google specialist to help users start their online advertising campaign.

In 2005, Google launched the Google Advertising Professional (GAP) Program to certify individuals and companies who completed AdWords training and passed an exam. Due to the complexity of AdWords and the amount of money at stake, some advertisers hire a consultant to manage their campaigns.

In 2008, Google launched the Google Online Marketing Challenge (http://www.google.com/onlinechallenge/), an in-class academic exercise for tertiary students.Over 8,000 students from 47 countries participated in the 2008 Challenge, over 10,000 students from 58 countries took part in 2009, about 12,000 students in 2010 and almost 15,000 students from 70 countries in 2011. The Challenge runs annually, roughly from January to June. Registration is at the instructor rather than student level.

In 2009, Google revised the AdWords interface, introduced Local Business Ads for Google Maps and Video Ads.

The AdWords system was initially implemented on top of the MySQL database engine. After the system had been launched, management decided to use Oracle instead. The system became much slower, so eventually it was returned to MySQL. The interface has also been revamped to offer better work flow with additional new features, such as Spreadsheet Editing, Search Query Reports, and better conversion metrics.

As of April 2008 Google AdWords no longer allows for the display URL to deviate from that of the destination URL. Prior to its introduction, Google paid advertisements could feature different landing page URLs to that of what was being displayed on the search network. Google expounds that the policy change stems from both user and advertiser feedback. The concern prompting the restriction change is believed to be the premise on which users clicked advertisements. Users were in some cases, being misled and further targeted by AdWords advertisers.

As of December 2010 Google AdWords has decreased its restrictions over sales of Hard Alcohol. It now allows ads that promote the sale of hard alcohol and liquor. This is an extension of a policy change that was made in December 2008, which permitted ads that promote the branding of hard alcohol and liquor.
