I have been tired by applying for adsense and still ignorance about the reason that they are not approving adsense for site. I have more than 70 posts on my blog. When I think it is enough, then google says add more contents. But, they don't mention how many posts. Is there anyone that tell me how many posts are good enough to get approval?
Try after making 100 posts, and be sure each category on your blog must have some posts, no category should be empty. rather than that Google have now make their rules very strict for approving new accounts. be sure your content is unique too now
There is no mentioning of number of posts required even few quality posts are enough.. I got my approval when I had only 20-25 posts... Quantity does not matter, quality matters.
Main thing is traffic from Google search engines, if you are getting traffic from Google search engines at least 100/daily you can apply and there is good approval rate too.
Traffic would be the concern which Google is taking in consideration. You must satisfy the criteria for the same.
