One of the most important criteria the YouTube guys will use to evaluate your application is the audience you reach on YouTube. They don't reveal what are the requirements, but I've seen many people say these are the ballpark numbers you need to have before getting accepted:
- at least 1,000 subscribers at least 1,000 views on all your videos at least 10,000 channel views
These are the very minimum though, if you want to make sure you'll get accepted I would aim for 5,000 subscribers, 50,000 channel views and over 1,000,000 upload views total.
