There is 6 easy secret way you need to follow for AdSense Program Approval

Many many application for Adsense program are being rejected daily. 

But why is that? the certain answer is- google assure the better experience for Adwords Advertisers. So to be approved by AdSense Program, any site must meet the policies prescribed by google. But from my experience I can tell you the 6 most important things which may typically works for adsense program approval.

1. Make sure each posts contents is fresh and unique. 

2. Posts contents should be relevant with your Post Headline and should have Keywords around the contents the same keyword you used in Headline. (Do not use too many keywords)

Example: You write 2 posts with a Headline like as following

(a) How to Add Pagination styles in Blogger Blog?

Your contents should be relevant to the headline mentioned above. And use a keyword 2 to 3 times following the Headline above. Here keyword matches "Blogger Blog". So the review team and Google crawl can understand what about your contents. 

(b) How to insert robot.txt in blogger Blog?

Your contents should be relevant to the headline mentioned above. And use a keyword 2 to 3 times following the Headline above. Here keyword matches "Blogger Blog". So the review team and Google crawl can understand what about your contents.  

So 2 posts in above easily guessable that your blog is help for blogger. 

3. You must publish contact me/us, about page, terms of use, Privacy & Policy in your blogs. Without this page, it is difficult to get AdSense approved. Because the AdSense application reviews team may be check about page to know a blog better and Privacy & Policy page to know certain rules of your contents. As a publisher you should eliminate your contents through these two page to meet the qualification which need an advertiser. 

4. Do not use any naked/broken plugin in your blog side bar. This means useless or irrelevant plugin. 

5. Write at least 300 words for any posts. Never post only headline containing the contents part with some link. Generating traffic with awesome Headline but not enough contents is bad for your blog.

5. Do not use too many image, link, videos & Flash animations in your posts. 

6. Never try to display any other ads from other ad syndication in your blogs until you approved by AdSense Program. If you already did that try to delete all code frames from your blog

Wish you Good Luck.
