Use as steel-man material, not current benchmark.\n\n**Companion 2025 data point:** Stratabeat's B2B SaaS data — *\"websites that published 9+ blog posts per month saw a 20.1% increase in monthly organic traffic.\"* Same direction, single-source, more recent.\n\n**The honest reading:** volume-correlation data points one direction; the AI-citation and trust dimensions point the other. Research-first competes on the trust/citation axis. **Both can be true:** a research-first SMB writing 1 article every 2-4 weeks captures different value than a content factory writing 16+/month.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"newton-platformer-retreat-from-daily-april-2026","title":"Casey Newton / Platformer retreat from daily cadence (April 2026): \"More scoops, less aggregation and analysis\" — AI commoditizes daily synthesis","kind":"reference","scope":"business","link_type":"relates-to"}],"incoming":[{"slug":"research-brief-research-before-pages","title":"Research brief: Research Before Pages — methodology for KB-backed websites (piece 14 of 15)","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-05-22T20:46:33.375Z","updated_at":"2026-05-22T20:46:33.375Z"}
