So you are an Adsense publisher, and its a good source of income. And as far as my experience goes there isn’t any Ads company which pays as good as Google Adsense program. So, the point is you don’t want such a good source of income to be closed down by doing those stuff which are not accepted by Google.

Below are a few tips to avoid getting banned by Google.

Content

Google has a very strict policy when it comes to the content on your website. If your website has content related to any of the topics given below, then its better to change it before you get banned. The topics are:

Pornography (adult or mature content)
Violent content
Content related to racial intolerance or advocacy against any individual, group or organisation
Excessive profanity
Hacking/cracking content
Gambling or casino-related content
Illicit drugs and drug paraphernalia content
Sales of beer or hard alcohol
Sales of tobacco or tobacco-related products
Sales of prescription drugs
Sales of weapons or ammunition (e.g. firearms, firearm components, fighting knives, stun guns)
Sales of products that are replicas or imitations of designer goods
Sales or distribution of coursework or student essays
Content regarding programs which compensate users for clicking ads or offers, performing searches, surfing websites/emails
Any other content that is illegal, promotes illegal activity or infringes on the legal rights of others

Copyrighted Material

AdSense publishers may not display Google ads on webpages with content protected by copyright law unless they have the necessary legal rights to display that content

Ad Behavior

AdSense code may not be altered, nor may the standard behavior, targeting or delivery of ads be manipulated in any way that is not explicitly permitted by Google. For instance, clicking Google ads may not result in a new browser window being launched.

Ad Placement

Publishers are encouraged to experiment with a variety of placements and ad formats. However, AdSense code may not be placed in inappropriate places such as pop-ups, emails or software. Publishers must also adhere to the policies for each product used.

Site Behavior

Sites showing Google ads should be easy for users to navigate. Sites may not change user preferences, redirect users to unwanted websites, initiate downloads, include malware or contain pop-ups or pop-unders that interfere with site navigation.

Competitive Ads and Services

In order to prevent user confusion, publishers may not display Google ads or search boxes on websites that also contain other ads or services formatted to use the same layout and colours as the Google ads or search boxes on that site. Although you may sell ads directly on your site, it is your responsibility to ensure that these ads cannot be confused with Google ads.

Google Advertising Cookies

AdSense publishers must have and abide by a privacy policy that discloses that third parties may be placing and reading cookies on your users’ browsers, or using web beacons to collect information as a result of ad serving on your website.

Product-Specific Policies

AdSense for content: Up to three ad units and three link units may be placed on each page.

AdSense for search: A maximum of two Google AdSense for search boxes may be placed per page. Also, a single link unit or a search box, but no other Google ads, may be placed on pages with AdSense for search results. Queries must originate from users inputting data directly into the search box and cannot be modified. This includes pre-populating the search box with terms or hard-coding direct links to search results pages. AdSense for search code may not be integrated into any software application such as a toolbar.
