On‑page structure for editors
This hub should act as a gateway rather than a long encyclopedic article. Keep the top paragraph as the definitive AEO answer (60–80 words). Below that, present a single short “Where to go next” section: one concise sentence per reader intent that links to the single most relevant child page. Avoid listing all pages as a menu; instead frame each recommendation as the best next step for a specific goal.
Include a compact categorized ItemList that summarizes the topical coverage in plain terms and embeds child links where helpful. Follow with a short “Most asked” block of six to eight items — each item is a one‑line question with a one‑line answer and a link to the in‑depth FAQ. Keep editorial voice authoritative and consumer‑focused: practical, non‑medical, and transparent about limitations (for example, say when a child page covers evidence limits or where to consult a professional).
For SEO and UX: use clear H2s, keep paragraphs under four lines, and avoid duplicating the navigation the template already provides. Where affiliate mention is needed, use a single soft CTA directing buyers to the Cost & Buying page and the site’s Brands or Compare pages for curated selections; place that CTA near the decision guidance rather than the top of the page.
