Domain parking refers to monetizing otherwise unused domain names via pay-per-click advertising.

There are numerous companies that exist soley to monetize "parked" domains in this manner. Most domain registrars "park" their customers' idle and unused domains and monetize them, often keeping the revenues for themselves.

If you have domain names simply "parked" with your registrar, you may decide you want to monetize them yourself. If you do, you need to select a domain parking company and then configure your domains so that web traffic to them goes to the parked page provider's system.

The domain aftermarket is very active. Many registrants registered quality names many years ago and never actually did anything with them (not even by monetizing them via domain parking).

These domains attract all kinds of players out of the woodwork. Including:

Domain flippers

These people probably already have a buyer for your domain lined up at a certain price. Their objective is to entice you to sell at a lower price, effectively creating an arbitrage situation for themselves
