1.) Use Real Names and NOT Nicknames

While this mistake is rarely done, there are a few people who unknowingly use their nicknames while registering. While there is nothing in a name, I feel using a nickname may get your account rejected. I always suggest using your real names.

2.) Apply Only Once

If you have two blogs both not having Adsense, do not apply for two Adsense accounts for both blogs. If you’ve submitted an application and have not received the approval or rejection e-mail, please do not apply for another account. I’m sure the e-mail will come. Though it will take time, it will come. Normally it takes about 2 days, but it may take more time if there are some holidays. Apply only once!

3.) Make Your Blog Has Good Content Both In Quantity & Quality

Adsense team only approves the sites which have good content both in terms of quality and quantity. They both should be in equal level. Concentrate on both the issues. I suggest focusing on “Quality” first because I feel people see the quality of the article and not the number of articles in your blog. So focus on quality (60 percent) + quantity (40 percent).

4.) Good Traffic

A blog with no or very less traffic is not at all suitable for Adsense. How can a blog with no visitors make money with Adsense? I mean if Adsense team will approve each and every account (Even sites with very less or no traffic at all) I think it will be useless. It will only increase the database size! :P

Make sure you have good traffic before you apply for Adsense.

5.) Make Your Site Look Professional

A site with unprofessional and messy look won’t get approved in Adsense. Along with the content the site style and look also matters.
A few tips for improving your site look and making it look professional:
1.) Use light colors.
2.) Keep design simple.
3.) Add links to all your important pages.
4.) Ensure easy navigation.
Hope the article helped you! If you follow the tips mentioned above I can ensure you that your account will be approved. Just follow all the tips and then apply.
