PPC (Pay-Per-Click) marketing firms manage online advertising campaigns on platforms like Google Ads and social media, where advertisers pay each time a user clicks their ad. They conduct keyword research, set up ad groups, write compelling ad copy, and optimize bids and budgets to maximize ROI. By continuously monitoring and adjusting campaigns, PPC specialists help businesses increase website traffic and conversions quickly. Effective PPC campaigns target relevant audiences and use data-driven adjustments to improve cost efficiency and achieve marketing goals.
