This is a network advertisements pricing model in which you pay only according to the number of users who click on your ads or email notifications. When you engage in the PPC (Pay Per Click) marketing model, your enterprise will purchase the keywords within specific search engines. PPC is different to the traditional intrusive ads. It presents a potential customer with your ad at the perfect time, when he or she is searching for a search term related to your very product. If they are not interested and don’t click, you pay nothing.
