Build a complete, prioritized SEO strategy for a site: topical authority map, winnable-keyword shortlist, content production pipeline, link-building plan, and technical baseline. Use when the user wants to grow organic traffic, asks 'how do I rank on Google', 'why isn't my site getting traffic', 'build me an SEO plan/strategy', 'what keywords should I target', 'how do I get backlinks', or wants to audit or scale their SEO — even if they never say the word 'strategy'. Produces an SEO Strategy Document with a scored keyword shortlist, a phased action plan sequenced by dependency, and a measurement plan.
