Intentionally or unintentionally people do some mistakes which cause cancellation of Google AdSense account. Difficult part is that Google don’t give you any kind of warning before canceling your account.

Few other facts are:

2. You loose all your previous earnings for which you didn’t get payment from Google.
3. Sites link with you will also come under radar.

As an AdSense published you could do few things to avoid cancellation of you AdSense Account. Please find the below tips our experts team came up with:

1. Read Google AdSense Online Standard Terms and Conditions:
   Most of us don’t read this. Actually we register to so many websites every day that it’s practically impossible to read their terms. But Google AdSense TOS is probably the one that we recommend you to read and strongly suggest to everyone that uses it reads it. (It’s a 17 point document which keeps updating time to time. If you don’t feel comfortable reading on internet, take a print and read it when you have some time.)

2. Don't click ads on your website.
   If you click ads on your site it violates the TOS because you are basically making money for yourself and costing the advertiser money when you clicked the ad.This is the most probable cause of AdSense account cancellation.
   
   
3. Don’t ask others to click on Google ads.
   Never try to make visitors click on adds. Users should click on Google ads because they're interested in the services being advertised. Encouraging users to click on your Google ads, either directly or indirectly, can lead to inflated advertiser costs and can cause your account to be disabled.
   
   
4. Don’t place Google ads on sites that contain prohibited content.
   Google ads may not be displayed alongside any type of content prohibited by our program policies, including adult or mature content, gambling-related content, or drug content.
   
   
5. Don’t employ pop-up prompts or automatic software installations.
   Sites showing Google ads may not prompt users to install software on their machines. Publishers must also not attempt to change users’ browser home pages automatically or via pop-up prompts.
   
   

Finally trust on Google as a long term partner for your business. Any wrong step for short terms gains could lead you towards Google black list. We don’t know what all new programs will launch in future by Google. Loosing their trust once could much more harmful then loosing an AdSense account.
