How much does advertising on Quora cost?
Quora ads are priced on a cost-per-click (CPC) basis, so you only pay for the clicks on your ads, not for impressions.
After setting a CPC bid, your ads will compete in an auction against other ads, and factors including your bid and the likelihood of a click determine the winning ad.
Due to the auction, there is not a pre-set cost for clicks. In general, the higher your bid, the more likely you are to receive clicks.
