There are alot of mistakes causes your Google Adsense's account has banned, follow these 10 common mistakes:
This is the main cause Adsense account banned. So do not ever click on your own ads. Google will remember all the times of login information from the IP number, browser, operating system ... to determine who can login to your account click on the banner or not. You should not think about the use of automated programs to click on their banner, they remember that Google is smart enough to know this!
2. Never changed the Adsense codes
Stay in your Adsense account, Google allows you to change colors, borders, font color, style, size banner. You are only allowed to change it in your account, any impact to the code of the Google ads are violating rules. Therefore you should not change it but the same as at first.
3. Do not put more than 3 banner ads, banner and a link or two of the Google search box on your website.
Actually, if you put 10 banner ads on your site, then from the 4th onwards banner will not appear again.
4. Do not use a double ads program like Google.
Google does not allow us to put the same code on their website that "competition" in which they compete. Opponents here I would say is an advertising program based on other content such as Yahoo Publisher Network. However, you can use a PHP code to alternate the two types of banner displays, as long as it does not appear together on a web page.
5. Do not tell anyone sensitive information such as CTR, CPM.
This is a Google's rules can be considered to prevent rushing to create the same page. For example, someone on the iPod website, have a high CTR or CPM is also high ... everyone moved to the "job" then woe to the Ipod. Therefore you should not tell anyone how information, especially on the forum post or publish on your website. However, you are entitled to "small talk" to people about the total amount you earn in a month.
6. If you intend to name the banner, you are only allowed to have two choices are "Sponsored Links" and "Advertisements".
Any word on what the other two words are considered to be violating regulations. I also met many people who are labeled "Hot Links", "other articles" on their banner. You do not do it if you do not want your account closed.
7. Do not set the default link is opened in another window.
If you think you want the Google link is opened in another window is a good idea. However, Google and they do not think they like their link to the right opens the page.
8. Do not create multiple accounts for different sites
A Google Adsense account you can use for many different pages. So you do not need to create multiple accounts for multiple sites, because if they know you'll be closing your account. So no need to use much when they let you use one account for multiple sites.
9. Only Google's banner on the page content
Advertisers only pay for their banner placed on pages with content. So if you put the banner at the top thanks, ... sort of a redirect pages with no content. This also violates the rules of Google.
10. Avoid using keywords on a page
You should write an article with content, and the few that there are a few keywords that you want Google to place under its banner. But do not do a page outside the content does not have that keyword, such as breaking the law and if found your account may be closed.
