You don't need any articles to get approved. I found it easy to apply with online stores. And you definitely don't need any visitors. Also, you can try applying with a site that's not in English, maybe they have a harder time checking these or something, but all my non-english sites have been accepted easily.
I going to call BS on this one. How can you apply and get approved for so many sites when you are only ever allowed one adsense account?
I sing up for AdSense more than 20 times AdSense banned my email and site then I created the new email and created hosted account from youtube directly in one day accepted my hosted account after one year I order to change my host account to standard account AdSense accepted my order now I have the standard account without any problem. if Adsense doesn't accept your site first create hosted account from youtube then put ads on your site
If you have good informative articles posted on your website (original) then you need not to worry about the number of the article as there is no number limit for google to be approved in Google Adsense.
If you have unique quality articles you will get approved soon. Don't care about quantity and how many visitor per day you have
According to me, quantity doesn't matter a lot. All you need is to have quality and unique content. Create sites for your users, don't create your site for adsense only. if you create a site which is helpful to your users, You can get your adsense account approved.
