It very difficult to get adsense approved as you have to follow google’s Terms and Conditions. But after approval many account get ban which is very disapointing. Here are the Reasons why google ban your adsense account: 1. If you are clicking on your own ads, asking your readers, friends to click on the ads or using automated scripts and programs using proxies to click on your ads, you will surely get banned. Lot of people think they can get it away but they forget it is not possible to fool almighty google. 2. If you have too many ads and very little content, you may have very high CTR which often triggers google filters which result in manual review of your sites and this may cause your adsense account getting banned. Normal CTR should be between 0.05% to 10%. And normally 3 ads per page are recommended. 3. If you are violating google adsense policies like hiding ads, showing ads on pages where you should not, your website having pirated content then too it will get banned, the sites as well as your account. 4. If you are applying or having multiple adsense account, can also lead to ban your both the accounts. you can use one adsense account in your 100′s of different blogs. 5. If google sees you are deliver very poor quality traffic which is not converting, google may also ban your adsense account. source: allblogtip.com
It is the maximum, however you will not be banned if you put more than 3 on a page, some of the ads just aren't going to show up
