You will need to exercise discretion and confidentiality as it relates to your Adsense account. There are several reasons for this, and just one of them is that Google does not want you to be helped by your friends and family. The simple thing about it is they can easily track high amounts of clicks from any particular geographic location. Naturally, your account will get shut down very quickly; so that is one thing you need to avoid doing.
Never engage in keyword stuffing on any site. Google’s software is just too smart to let that one pass, and it is a sure-fire ticket to being banned from Adsense. Make sure your keyword density is not more than 4% to 5% – anything more than that puts you in the risk zone. It is not hard to see realize how important it is to take strict measures when it comes to maintaining your Google AdSense account and preventing it from getting banned. It is really very simple, merely stick to their guidelines and procedures, and you will be fine.
