Keyword research is the process of identifying the search terms your target audience uses and evaluating which ones are worth targeting based on search volume, competition, and business relevance. It is the foundation of any SEO strategy because it determines which pages you build and what those pages need to say.
Volume alone is not a useful metric. A keyword with 500 monthly searches from decision-makers at SaaS companies is worth more than one with 10,000 searches from students writing essays. The question is not how many people search for something. It is whether the people who search for it could become clients.
Effective keyword research for B2B sites covers three layers: high-volume category terms that establish topical authority, mid-funnel comparison and alternative terms where buyers are evaluating vendors, and bottom-funnel terms where intent is close to a purchasing decision. Most B2B SEO programs underinvest in the second and third layers, which are the ones that generate leads.
