Have Sufficient Contents or Posts:
You must lead sufficient contents or posts on every page and category. In total, you should have 20-30 blog posts on your whole blog. This is not an official declaration. But, I recommend everybody to at least have it. So, you should have at least 8-10 posts in every category, tag and page. Google Adsense told that we must have sufficient contents in every single web page. So, we should add contents in all pages and categories. There shouldn’t be any blank page without any content. And these posts have to pass the minimum length of 800-1000 words as it is the best blog post length. The more you increase the length, the more you go towards to get Google Adsense approval.

Be Serious to Content Images:
Google Adsense doesn’t approve blogs if they lead to copyrighted contents. Copyrighted means the things that have been copied from others directory without their permission. And we make fault every time when choosing an image. Some people just go to an image directory, take their suitable images and upload these on their blogs. Did they ever check if they have permission to use these? The really sad news is that, most of the webmasters who fail to get Adsense because of this copyrighted law. And this is really caused by copyrighted images.

You Should Not Have Adsense Prohibited Content:
Adsense has directly told that, sites with adult contents, copyrighted contents, drug alcohol-related contents, hacking cracking contents, violent contents, weapons related contents and other illegal contents will not be approved.
  • Using Adsense on an unsupported language blog  At the time of writing, Google doesn’t support all languages to qualify for Adsense program. If you have an approved AdSense account, and you are using it to show it on a blog, the language of which doesn’t qualify as per Adsense TOS, you need to make changes ASAP. If you use any method to make your blog multi-lingual and serve ads on it, it can be considered a violation.
  • Sending ads on email  Many publishers started the trend of sending AdSense adverts within the email, and sometimes it goes viral. Google finds it against the program policies.
  •  Copyright content   If you are running Adsense on a site that distributes copyright content like Movies, songs or any other files, you are most likely to get an instant ban. Adsense doesn’t allow putting Adsense on the site that distributes copyright stuff.
Visitors Are Not a Factor for Approval:
For getting Adsense approved, visitors are not a factor. Because you will get approved depending on your blog quality. It is sure that the Adsense moderator will never check for visitor count. So, don’t worry about visitors. But, for generating revenues, you must have enough visitors.
