Summarize with AI

TL;DR. Nine rules govern whether AI engines cite a page. They are not ranked by importance. They are jointly necessary: a page that fails any one of them is functionally invisible even if it passes the other eight. Use the table below as a pre-publish checklist.

The 9 rules

#RuleWhat it demandsWhere to learn
1BLUF40–80 word direct answer in the first paragraphLesson 5.3
2Question-format headersH2s phrased as the reader's actual questionLesson 5.7
3Semantic HTML hierarchyOne H1, H2s, H3s, no skipped levelsLesson 5.7 + Module 4.5
4Justification attributesPros/cons, comparison tables, "best for X" claims (see Sentiment tab)Lesson 5.4
5Evidence and dataNamed stats, dates, analyst sources, quantified claimsLesson 5.6
6E-E-A-T signalsNamed authors with credentials, bylines, review datesLesson 5.8
7JSON-LD schemaArticle, FAQPage, HowTo, Organization, ProductModule 4.4
8Chunkability50–120 word self-contained paragraphsModule 4.6
9Freshness signals"Last updated" line, recent stats, dateModified schemaLesson 5.5

The two rules that live in Module 4

Rules 7 (JSON-LD) and 8 (chunkability) are technical implementation. Module 4 covers them as SEO gaps because the diagnostic is structural, not editorial. Rule 3 (semantic hierarchy) sits in both modules: the technical diagnosis is in Module 4.5; the writing craft of question-format headers is in lesson 5.7.

The pre-publish checklist

Before you hit publish on any page meant to answer a target prompt, run this:

  1. First paragraph is a 40–80 word direct answer to the target prompt (Rule 1)
  2. Every H2 is phrased as a question (Rule 2)
  3. One H1, H2s, H3s, no skipped levels (Rule 3)
  4. Page contains at least one pros/cons list or comparison table (Rule 4)
  5. Every major claim has a named stat or source (Rule 5)
  6. Author is named with credentials, page has a review date (Rule 6)
  7. JSON-LD schema is valid in Google Rich Results Test (Rule 7)
  8. Every paragraph is 50–120 words and stands alone (Rule 8)
  9. Visible "Last updated: [Month Year]" line on the page (Rule 9)

Any "no" is a rewrite.

Why all 9 are jointly necessary

A page can rank on Google with 4 of 9 rules passing. It cannot get cited on ChatGPT with 8 of 9. AI engines do not weight rules; they gate on them. Miss one and the chunk gets deprioritized.

The exception: brand pages (homepage, About, product) often lean hardest on rules 4, 5, 6, 7. Blog content leans hardest on 1, 2, 8, 9. But the 9-rule minimum still applies everywhere.

Do this now:

Copy the pre-publish checklist into your team's CMS template or Notion. Require it on every page meant to answer a prompt you track. No checklist, no publish.
