Why Are PPC (Pay Per Click) Ads Are So Popular?

[a1florist]

In the offline days long before the World Wide Web and PPC (Pay per click) ads came along, publishers as well as radio and TV stations experimented with something called PPO (pay per order) and PPR (pay per response) or PPL (pay per lead) advertising. As the names suggest, these were ads where the advertisers either paid per lead generated or order generated. But the truth is that these ads never really took off and were never widely accepted.
