Whenever we want to know about something or about a certain topics the first and foremost word that comes to our mind is “google”. Google has become the answers of all your quarries. But have ever tried to know that from where Google is earning its business or revenue? Have you ever noticed that whenever you are searching a particular website then a number of ad come up with new and varied for of offers for you and you click on those ads. Yes, that is the biggest source of income for google. As it is being one of the greatest sources of income and also having large source of ads then google has to maintain a very healthy relation of trust should be maintained with both of the advertiser and also with the publishers. Generally, a publishing company has to buy advertisement from google Adwords and through this google AdSense programmes these advertisement are getting published on the websites and the google earns a large amount of revenue. Now the advertisers have to rely on google on the placement and the relevance of their ads, whereas on the same hand it’s also on google part to maintain their security and protection also. As this is the cycle of business so that is why there is a certain fraudulent activities that are being done both from the publishers end. To earn more profit usually the publishers go for false click through click exchange programme, by this program the publishers click on the advertisement of other publishers and then that publisher click on the ads of the other publisher’s ad in this way the entire flow goes on and thus the publishers gained a huge amount of money within a very short period of time. Usually the advertiser, who will be the highest bidder will be selected he will be at the top spot. And once that advertisement is being selected at the top, the advertiser has to pay a certain amount of fee to the search engine at the every click done by the searchers, that revenue which will be earned by google, at a certain proportion or percentage that will shared with the publishers. As I have already told earlier that Google AdSense account is the easiest way for the website publisher who can publish ads of different size and display, so it is very important to keep your account safe and secure from such malicious and fraud activities that are being done due to earn money.
