Pay per click (PPC) advertising is a model where advertisers pay each time a user clicks on their ad. PPC ads often appear at the top of search engine results or on other websites. With PPC, advertisers bid on keywords related to their business to have their ad displayed. Each click from a user represents attention and potential traffic to the advertiser's website. To be effective, PPC requires identifying high-value keywords, determining a budget, and targeting ads toward the right consumer personas. Understanding PPC, keywords, budgets, and customers allows advertisers to reach the right people and guide them toward making purchases.
