Use when researching competitors in a market — identifying direct, indirect and adjacent players, auditing their websites, SEO, paid ads (Google Ads Transparency Center, Meta Ad Library, TikTok and LinkedIn ad libraries), social presence, content strategy and how AI assistants describe them, then running SWOTs and finding actionable market gaps. Also use when someone asks "who are we really competing with", wants a competitive landscape brief, or needs whitespace for a positioning or launch. Don't use for financial due diligence, patent or IP analysis, or pricing models.
