Pay per click (PPC) is an advertising model used on search engines, advertising networks, and content websites/blogs, where advertisers only pay when a user actually clicks on an ad to visit the advertiser's website. Advertisers bid on keywords they predict their target market will use as search terms when they are looking for a product or service. When a user types a keyword query matching the advertiser's keyword list, or views a page with relevant content, the advertiser's ad may be shown. Google Adwords Reach people when they are actively looking for information about your products and services online, and send targeted visitors directly to what you are offering. With AdWords cost-per-click pricing, it's easy to control costs—and you only pay when people click on your ad.
