Pay-Per-Click is a digital advertising model used on platforms like Google Ads, Microsoft Ads, and social media networks. Advertisers bid on keywords or audience segments, and pay a fee each time their ad is clicked. PPC allows businesses to appear immediately at the top of search results for competitive terms, bypassing the time investment required for organic SEO. When managed well, PPC delivers highly targeted traffic and measurable ROI, complementing long-term SEO efforts.
