 Monetizing web-spaces and links such as this soon gave way to auctioning off domain names.The final step that led to auctioning off domain names was Google’s Pay per click (PPC) auction model which allowed bidders to buy search terms.This allowed webpage owners to sponsor a keyword so that their ad could appear each time a user searched the term on Google, and thus increased the likelihood of the ‘clickthroughs’ their sponsor ad obtained.
