Why? You say. Google is so rich, losing some pennies won't hurt.

Well. Probably. But when I say you shouldn't, trust me. You really shouldn't. These are just some reasons:

1. You can't cheat Google

Every once in while, someone will comes out with ingenious idea to get more money from adsense in less than honorable ways. For help visit www.googleatmcash.com. He will announce to the whole world, posting in every forum and tell people how smart he is. His idea is always untraceable by google, it is always original, and it always gives easy money.

What he doesn't know is, few months after that, he will get caught by Google, always. And his adsense account will be disabled. Always. And he is banned from ever applying for adsense account again.

Google is a giant, with 2005 revenue of almost US$ 10 billions, and profits of more than US$ 1 billion. A large chunk of this comes from Adwords / Adsense advertisements.

More click fraud means less trust, less advertisers and less money, to the extent that if unsolved it will bring collapse to pay-per-click advertisement business.

They have money and ability to bring together many of the smartest and brightest engineers and scientists on earth, has been doing that and will continue to do so. How smart do you think you are that you can outsmart collaborative effort of the brightest brains?

You might be able to pull through for two or three months, but eventually the fraud detection algorithm will catch up and you are caught.

2. Cheating = stealing

No matter how you want to justify, face it, cheating is stealing. You are not only stealing from Google, but also from Adwords publishers. Majority of these are not big companies, but small webmasters depending on Internet to make a living.

Moreover, even if your morality (or lack thereof) permits stealing from your own fellow, bear in mind that stealing is illegal. Regardless of whether it is done offline or online, a crime is a crime. You might get jailed for that.

In fact, Google has started to bring adsense fraudsters to court a few months ago. Some were jailed, and some others were fined heavily.

3. It is just too easy to earn more, legally

Let's say you managed to cheat adsense undetected. You don't use clickbot or proxy or click-ring or paid clickers. You managed to somehow get the clicks from distributed IP. You don't use pop-ups, spy ware, adware. You are careful that your CTR does not exceed 10%. Still, your earning is limited. There is a cap you can't cross; else you will invite unwanted attention to your account.

With so much effort to cover your traces, actually you will get better result if you concentrate your effort to improve the website.

Write more contents, submit articles, improve on your search engine optimization, improve adsense placement, and you can get the same earning or even more. Sure it will take some time, but this is legitimate.
