B2B advertising is the use of paid channels to reach business buyers, create awareness, generate demand, and drive leads and pipeline for products or services sold to other companies. It is distinct from B2C advertising in its audience (professionals making purchase decisions on behalf of organizations rather than consumers buying for themselves), its targeting mechanics (job title, company size, industry, and technographic signals rather than demographics and interests), and its conversion timeline (multi-quarter sales cycles rather than immediate transactions). B2B advertising works best as part of a coordinated account-based motion; see the ABM playbook for how the channels fit together.
