- The first and the most important thing that you must do before you apply for AdSense is to thoroughly read the terms and conditions for AdSense publishers. Devote some time picking each clause, and try to understand the exact meaning of it. You can take help of search engines and discussion forums to get some idea about those common mistakes that can get you banned from Adsense program. Once you have read and understood the terms and conditions, half the battle is already won.
- The most common problem is click fraud. Some "get rich quick" publishers try this in different ways, by clicking their ads themselves and some more smart try to fool by asking their friends or relatives in different cities to click on their ads. Google is giant of PPC advertising and knows how to detect such fraud. Sometimes publishers fall victim of click bombing without knowing about it. They boast about their sites to relatives and friends and unknowingly fall into trap. Their relatives or friends start clicking on his ads to help him in his business without his knowledge, and suddenly one day he cannot enter his AdSense account. Never tell about your sites that are serving ads to your friends and relatives.
- Sometimes publishers do not read the terms and conditions carefully and put ads on pornographic, gambling, and drug sites. It is clearly stated again and again by Google that ad code should be pasted on a web page that adheres to AdSense Terms and Conditions.
- Do not put ads on registration and thank you pages. Ads on Pop ups are also not allowed. It will get you banned permanently.
- Do not modify the AdSense ad code at any cost. Whatever customization you want to do, you can do through wizard in your account, but once code has been generated never show your programming skills with the code manually.
- Some publishers start disclosing their ads data like eCPM, CTR publicly, which is strictly prohibited under the terms and conditions. Under no circumstances you are allowed to share this sensitive data with anyone else.
- Sometimes impatient publishers ask their site visitors to click on their ads and help them to earn. Again it will get your account banned permanently if you try to lure visitors to click on your ads.
Important Tips for save your Adsense!
However there are some facts you need the know about your most reliable source Adsense. If you don't want to get banned from Adsense and spend rest of your life looking for a subsitute, keep some important facts about Adsense in your mind:
1. Invalid Clicks
Google has a strong policy to prevent invalid clicks to keep their advertisers pleased. Don't forget that Google guys are propably smarter then you so don't even bother creating artificial traffic/clicks.
2. Own Clicks
Don't ever click your own ads. Even if the ad actually interests you or you just wanna check out if the ads work. Google has the magical powers to sense you clicking your own ads so be careful. If you click your own ads by mistake inform Adsense about the situation. 1 or 2 clicks won't get you rich so it isn't worth the risk.
3. Encouraging Clicks
Don't ever use terms like "click my ads, visit my sponsors, make me rich, i will die if you don't click those links". (However you may use the term "Sponsored Links")
Don't try to trick users by hiding ads, showing as part of text etc..
Don't point out ads by arrows, images etc..
In this situation Google magic works again and you will be caught.
4. Contextual Ads
This one is a little confusing. Google allows other ads and PayPerClick programs to be placed on your website but other ads shouldn't be resembling google ads. So placing an ad linking to dirty sites is damaging google's reputation so that is prohibited (That's understandable).
Google also doesn't want competition so ads resembling Google Ads isn't allowed. That one is a little confusing. This term may be to prevent Yahoo's affiliate service (which looks like Google ads in a sense). So be cautious before placing other ads to your site.
5. Illegal Content
I think I don't have to mention mature content, hacks/cracks are illegal. You have to be careful with the material you publish because sharing a mp3 you like with your community may seem innocent to you but that is illegal.
6. Site Behaviour
If you have got a free hosting you should check if your service is no pop-up. Many free hosting companies force their pop-up ads with your site and this will ban you from Adsense.
7. Ad Placement
You can't place more than 3 ad units and 2 search boxes. Even if you do place more than 3 ads they won't be displayed. There is no penalty for that but broken links in your website is a bad impression for your community.
In a nutshell, if you want that your AdSense account never get banned, simply keep yourself updated with the terms and conditions of Google AdSense and here to those guidelines.
