PPC stands for pay-per-click, a model of internet marketing in which advertisers pay a fee each time one of their ads is clicked. Essentially, it’s a way of buying visits to your site, rather than attempting to “earn” those visits organically.
Search engine advertising is one of the most popular forms of PPC. It allows advertisers to bid for ad placement in a search engine's sponsored links when someone searches on a keyword that is related to their business offering. For example, if we bid on the keyword “PPC software,” our ad might show up in the very top spot on the Google results page. Advertisers love PPC advertising because it allows them to make the key change in the optimization strategies to improve the Quality Score. This, in turn, increases the ROI for your PPC campaigns. It is one of the most profitable marketing channels when it comes to generating higher ROI.
