Google AdSense is a popular blog monetization tool because it's easy to join the AdSense program, easy to integrate ads into your blog and the ads don't take up a lot of space. However, Google has rules you must follow to avoid being banned from the AdSense program.
01: Do not Boost Clicks Artificially
Clicks on Google ads must occur because of true user interest. Google AdSense publishers can artificially boost the number of clicks on Google AdSense ads that appear on their sites, but Google frowns on this behavior and terminates the AdSense accounts of individuals who do the following:
• Click on AdSense links on your own blog
• Ask other people to click on the AdSense links on your blog
• Use any kind of automated process to increase clicks, whether you create the process or a third party does it for you
• Join with a group of people to click on AdSense ads on member's blog or website.
• Pay an individual or company to click on your ads
• Use verbiage such as "Visit these links," "Support us," or "Click the ads"
Additionally, Google does not allow ad placement on adult, violent, drug-related, or malware sites. A complete description of the types of prohibited sites is listed in the AdSense Program Policies.
02: Do not Display More Ads than Content
Google no longer limits the number of ads you can place on a single blog or webpage, but it still places restrictions. Google reserves the right to limit ads or ban AdSense accounts on web pages it considers unacceptable including:
• Pages that contain less content than advertising
• Pages that are automatically generated
• Pages with no content
03: Do not Ignore Webmaster Quality Guidelines
Google may not allow ads on blogs or web pages that don't follow the AdSense webmaster quality guidelines. They include:
• Blog and webpage owners must provide relevant content.
• Blog publishers can't duplicate the same content on several domains or sub domains.
• The blog or webpage must not exist solely to attract search engines.
04: Do not create More Than One AdSense Account
It might be tempting to create separate Google AdSense accounts and publish ads from both accounts on the same blog, but doing so is a violation of Google policies. While you can add more than one blog or website to your Google AdSense account, you may not have more than one actual account.
05: Do not Try to Trick Readers into Thinking AdSense Ads Are Not Ads
Hiding text link ads within the content of your blog posts to make readers think they aren't ads is a violation of Google AdSense policies. Bottom line: Don't try to disguise ads to increase clicks.
