I'm totally not an expert about Adsense but I have Adsense account and have cash out my earning few times. I will share how I get my GA account. I learned about this tips somewhere but cannot remember where and from who.

First, I make a blog using blogger.

Then I share download links for mp3 file. For 1 post, I make a list of mp3 title and the download link besides it. All in English.

I make a few posts. Less than 10 posts if I'm not mistaken.

Then I applied for GA. Received email from the team few days after that. Succeed!

And then, after that I start to build a travel blog (written in English. no longer exist.) and put GA in the blog.

I don't know if this kind of tips still work to get your GA application accepted because I did that in 2009/10 like that. Try if you want.
