  "title": "Keep a clear expertise spine before widening your public topics",
  "summary": "Range is useful after the reader can answer one simpler question: what do you reliably know?",
  "kind": "heuristic",
  "body": "Choose a small set of themes that share one expertise spine and let most public work reinforce it. Adjacent experiments can stay, but they should not make the main purpose unreadable. Google's guidance explicitly asks whether a site has a primary purpose or focus and warns against producing many topics mainly to capture search traffic. Apply that as a clarity constraint, not a niche prison.",
  "limits": [
    "A person may legitimately have multiple domains. The goal is navigable coherence, not artificial uniformity, and Google's guidance is not a numerical ranking rule."

    "Your site or professional feed covers many unrelated themes and it is becoming difficult to tell what you are known for."
