What is Paid Search (PPC) Marketing?

Paid Search (PPC) marketing is a digital advertising strategy where advertisers pay a fee each time their ad is clicked. It primarily involves bidding on keywords to display ads on search engine results pages (SERPs) like Google Ads and Bing Ads, but also extends to display networks and shopping ads. This strategy aims to drive immediate, targeted traffic to a website, increase brand visibility, and generate conversions (leads, sales, etc.). Services typically include keyword research, ad copy creation, bid management, landing page optimization, audience targeting, and performance analytics to maximize return on ad spend (ROAS).
