Note :
a. If you still don't understand the goal, think like how you are as a user of upwork where you want to find clients, as you are in the product market fit segment of upwork. In this case, upwork has not found (you) the right product market fit yet. So most likely, upwork will do a market research to find people like you and to deliver ads or PPC search to you after upwork found (you) the market fit.
