B2B SEO is search engine optimisation specifically tailored for businesses that sell products or services to other businesses rather than consumers. B2B SEO differs from B2C in targeting keywords used by decision-makers and professionals, typically with lower search volumes but higher value. The buying cycle is longer and involves multiple stakeholders, requiring content that addresses various stages from awareness to consideration to decision. B2B SEO content often focuses on thought leadership, technical specifications, ROI justification, and industry expertise. Keyword research targets business-focused terms, often more technical or niche than consumer queries. Success metrics emphasise lead quality over quantity, with attribution across longer, more complex customer journeys. B2B SEO requires patience as sales cycles extend over months, but successful strategies generate highly qualified leads with substantial revenue potential.
