Basically, anyone who is looking to make money fast should stay away from Wealthy Affiliate. There are plenty of “make money fast” e-books and courses out there, and they are all a scam (trust me). While Wealthy Affiliate is legit, they will absolutely never claim that they teach you how to make money fast. Building a legitimate online business takes time.
As far as how many articles you would need to get some good rankings this would depend on if you do in depth keyword research before you write the articles. From my own personal experience, I had around 30 articles before I started to see a good amount of traffic to my websites and started making sales. This would vary depending on how good of research you do and how well you follow the training.
There are a few different payment options that Wealthy Affiliate will accept. These include Paypal as being the safest and most popular one. If you don’t have a Paypal account you can sign up for one for free by going to Paypal.com. Besides taking regular Visa or Master cards you could also do an e-check from your bank and pay for your WA subscription that way. How Long Does It Take To Make Money With Wealthy Affiliate
