Industry-consensus for the mechanism.\n\n**Caveat:** Use for **mechanism, not magnitude**. The 10%/38% split describes the *distribution* of returns *among posts that earn traffic at all* — survivorship-flagged. It does not say \"if you write 10 posts, ~1 will compound\" — many companies write a hundred posts and none compound.","rationale_body":null,"metadata":null,"links":{"outgoing":[],"incoming":[{"slug":"research-brief-new-site-ramp-economics-june-2026","title":"Research brief: the time dimension of a new website — ramp economics, the J-curve, owned vs rented, and the AI-era verification (June 2026)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"ramp-j-curve-stage-3-compounding-conditional","title":"J-curve Stage 3 — compounding (Year 2+), CONDITIONAL: evergreen pages can accumulate traffic and links over years; HubSpot compounding-posts mechanism; not guaranteed","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"ramp-owned-vs-rented-compounding","title":"Owned vs Rented (compounding) — organic: CAN appreciate (conditional, HubSpot compounding-posts); paid: no compounding, each click bought afresh, ROI typically flat or declining","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-06-25T16:11:00.021Z","updated_at":"2026-06-25T17:07:10.774Z"}
