Pay-Per-Click (PPC)

Pay-Per-Click (PPC) is an online advertising model 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 Marketing (SEM) is one of the most common forms of PPC, where advertisers bid on Keywords relevant to their target market. When a user searches for that keyword, the advertiser's ad may appear, and they pay only if the user clicks the ad (Cost Per Click (CPC)). PPC is also used in social media advertising and Display Advertising. The effectiveness of PPC campaigns is often measured by Click-Through Rate (CTR) and Conversion Rate.
