There is no question that you can make some good money with Google AdSense, but you’re setting yourself up for disaster if you make any of these Top 10 mistakes!
1. Do not use fake information when opening your Google AdSense account.
Google says that’s a no-no and they will cut your account off and keep all the money you may have earned. Besides, trying to hide your true identity can cause serious problems with the I.R.S. or whoever your tax authority is.
2. Do not hack or modify Google AdSense code other than to change the parameters that Google authorizes you to change.
Any attempt to bypass Google’s built-in algorithms not only poses a danger to the integrity of the network, but it threatens the financial modle that Google operates under. You’re not dealing with some Mom-and-Pop company here, and Google has the legal muscle and deep enough pockets to drag you through every court in the land if you damage their business with your hacking antics.
3. Keep AdSense ads off of your registration, confirmation, and all "thank you" pages.
Don’t ask me why you can’t put your ads there. It makes sense to me that those would be wonderful locations. Google thinks otherwise, however, and doing so is a hanging offense according to their Terms of Service.
4. Do not display AdSense ads and a competitor's ads (like Overture's) on the same page at the same time.
That just makes plain good sense. Google doesn’t demand 100% SITE loyalty from you, but they do insist that their own ads not be cluttered up by offerings from their competitors.
5. Don't "beg for clicks" or provide any incentive for clicking on your Google AdSense ads.
This is a biggie and you see this rule violated all the time. Any of the “get paid to do stuff” sites that put Google ads in the member’s control panels are walking the plank and they don’t even realize it. Even those sites with the polite little messages asking you to “help keep my site running by clicking on our sponsor’s ads” are asking to be cut off if those happen to be Google ads.
