I recently had a chance to chat with one of the person from the nearby company. She works on Quora in her side gig. She is a consultant. Like she is into the interior design. And she has plenty of contacts in this space and she is using them for the development of the new jobs in this space.
She has generated decent revenue out of the Quora leads. And she answers questions, maintains her space and also connect with the users. And this has helped her get leads on the regular basis. She charges decently high so that she keeps only the premium clients.
Let's explain how the money can be made on the Quora.

Quora has stopped pay for answers system. At that time she made a good amount of money. Like she has around 100 answers and those answers still made her money. Now the model has changed though. Like now for answers she is making use of the profile.
Like say you have business around for the interior decoration. You have to promote your business and also have to get the attention. In that context you can see that people can be getting the leads in this sort of the content and the leads you get there.
You have to make sure to bring some value for the people. And they would connect back at you. Which is something you can see that you would get those offline gigs. If you get the gigs then you would be wondering what to do for next connections and the gigs. You would find a lot of connections develop here with the quora leads.
So people do have some value to bring there. Quora is good with spaces. Post your project updates there and also share your information. And that would add up and bring you some money. In all fairness that would bring you some value on quora which makes money at the end.
Focus on leads, create content and also ask for referrals. This way you would get some income going on Quora.
