When reading about PPC glossary one often times comes along terms like hit, click, conversion rate, ROI, Cost per click or CPC, page views etc. Pay per click glossary sometimes can also refer to the details of each visit that has been made to our website by a customer through an advertisement on another. The idea of PPC is to have a better control over our advertising expenses in the web and online world. PPC also gives the website owner an inherent interest in pushing the number of clicks on the advertisement we place on his website. Each click on our advertisement is the websites means of generating revenue. In the online world of ecommerce, where a customer or user is bombarded with endless ads and information overload is happening, the website owner will take the extra effort to place our ad where it will make the most impact. This PPC is a cost effective model.
