How does one get invited to the Quora Partner Program? What criteria do they use, or is it completely random?
I live in Germany. I got an invite to the Quora partner program the day I landed in USA for a business trip. So from what I understand, irrespective of the number of views on your answers, there is some additional eligibility criteria for you to even get an email invite.If you read the terms of service, point 1 states:Eligibility. You must be located in the United States to participate in this Program. If you are a Quora employee, you are eligible to participate and earn up to a maximum of $200 USD a month. You also agree to be bound by the Platform Terms (https://www.quora.com/about/tos) as a condition of participation.Again, if you check the FAQ section:How can other people I know .participate?The program is invite-only at this time, but we intend to open it up to more people as time goes on.So my guess is that Quora is currently targeting people based out of USA, who are active on Quora, may or may not be answering questions frequently ( I have not answered questions frequently in the past year or so) and have a certain number of consistent answer views.Edit 1: Thanks to @Anita Scotch, I got to know that the Quora partner program is now available for other countries too. Copying Anutau2019s comment here:If you reside in one of the Countries, The Quora Partner Program is active in, you are eligible to participate in the program.u201d ( I read more will be added, at some point, but here are the countries, currently eligible at this writing,) U.S., Japan, Germany, Spain, France, United Kingdom, Italy and Australia.11/14/2018Edit 2 : Here is the latest list of countries with 3 new additions eligible for the Quora Partner program:U.S., Japan, Germany, Spain, France, United Kingdom, Italy, Canada, Australia, Indonesia, India and Brazil.Thanks to Monoswita Rez for informing me about this update.
