AI answer engines quote sentences they can retrieve, attribute to a known source, and lift without losing meaning. For a service business that means pages that state who you are in plain terms, open with the answer, carry specific sourced facts under a named author and a real date, and are backed by structured data that says exactly what the page says. Google's guidance, updated in 2026, is that no special files, markup or chunking are needed; the only published controlled study found that adding citations, quotations and statistics raised visibility in generated answers, while keyword stuffing lowered it. What follows is the checklist we apply to our own pages.

Key takeaways

  • Google's guide on generative AI features (published May 2026) says SEO best practices "continue to be relevant", that you don't need "new machine readable files, AI text files, markup, or Markdown", and that "there's no requirement to break your content into tiny pieces for AI to better understand it".
  • Google's FAQ rich result stopped appearing in Search on 7 May 2026. An FAQ section is still worth writing because engines quote the answers; FAQPage markup no longer earns a visual result.
  • In the GEO study (KDD 2024), adding quotations scored 27.8 against a baseline of 19.5 on its main visibility metric, statistics 25.9, cited sources 24.9; keyword stuffing scored 17.8, below the baseline.
  • Google's structured-data policy is the parity rule: "Don't mark up content that is not visible to readers of the page" and "your structured data must be a true representation of the page content."
  • Trust signals are mundane: a byline, an author page with ProfilePage markup, an Organization node with sameAs links, consistent facts across pages, and an honest dateModified.

What the evidence says

Two sources matter more than the rest of the advice industry.

Google, in its own words. The "AI features and your website" page (updated December 2025) states "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary", and lists the basics: helpful, reliable, people-first content; important content "available in textual form"; internal links; page experience; "making sure your structured data matches the visible text on the page"; crawling allowed "in robots.txt, and by any CDN or hosting infrastructure". The longer guide published in May 2026 adds the emphasis on "non-commodity" content: commodity content "is often based on common knowledge, which could originate from anyone", and mass-producing pages for query variations "violates Google's scaled content abuse spam policy". It also records that Search ignores llms.txt (changelog, 15 June 2026).

The GEO study. Aggarwal and colleagues tested nine content changes on the same pages and measured how much of a generated answer drew on them (Position-Adjusted Word Count, baseline 19.5). Quotation Addition scored 27.8, Statistics Addition 25.9, Fluency Optimization 25.1, Cite Sources 24.9, Technical Terms 23.1, Easy-to-Understand 22.2, Authoritative 21.8, Unique Words 20.7 and Keyword Stuffing 17.8. The authors report the best methods "improve upon baseline by 41% and 28%" on their two metrics, and that citing sources is "particularly beneficial for factual questions". They caution that the per-domain tags "can be noisy", so treat the ranking of methods as a guide, not a law.

Put together: write pages a careful person would want to quote, and keep the markup honest. Our GEO guide covers crawler access and measurement; this checklist covers the page itself.

The writing checklist

1. Entity statements

Somewhere on every important page, one sentence states who you are in the form an engine can reuse: "Impinge Solutions is a web and mobile app development company, building custom websites and mobile apps, founded in 2005 with offices in Mohali (India) and Ontario (Canada)." Repeat the same facts, in the same words, on the home page, About page and Organization markup, for example:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Impinge Solutions",
  "url": "https://www.impingesolutions.com/",
  "description": "Custom websites and mobile apps from a team trusted by 2000+ clients since 2005. Offices in Canada and India.",
  "foundingDate": "2005",
  "address": [
    { "@type": "PostalAddress", "addressLocality": "Mohali", "addressCountry": "IN" },
    { "@type": "PostalAddress", "addressRegion": "ON", "addressCountry": "CA" }
  ]
}

Inconsistent numbers across pages are the most common reason an engine hedges or picks a competitor.

2. Answer-first paragraphs

The first 60 words answer the question the title asks. Then explain. Google's guide says "there's no ideal page length"; the opening is what gets quoted, and a reader who wants depth keeps going.

3. One fact per sentence where it matters

Engines extract sentences. "Our migration improved performance" is unquotable; "the migration cut the home page's mobile Largest Contentful Paint from 15.3 s to 2.0 s (Lighthouse lab data, October 2026)" can be lifted intact with its source, here our WordPress to Astro migration write-up.

4. Statistics with sources

Every number carries a link to where it came from, inline and in a sources list. Numbers you generated yourself carry the method and the date. The GEO result for statistics is the second-strongest in the study; fabricated statistics are the fastest way to lose trust when the engine surfaces the source and finds nothing.

5. Quotations with attribution

Quote the primary source (a regulator, a vendor's documentation, a standard) rather than paraphrasing it. Quotation Addition was the top-scoring method in the GEO study. Quote people only with permission and a name, role and organisation.

6. Numbered procedures and comparison tables

Steps and tables are extracted cleanly and answer "how do I" and "which should I choose" queries directly. One of each per page is enough; a page that is all lists reads as filler.

7. An FAQ with complete-sentence answers

Four to six questions, each answered in 40 to 60 words that stand alone. Since May 2026 this earns no FAQ rich result in Google, but the answers are exactly the length engines quote.

8. Bylines, dates and disclosure

Google "strongly encourage[s] adding accurate authorship information, such as bylines to content where readers might expect it", and asks whether "the use of automation, including AI-generation, [is] self-evident to visitors through disclosures". Show the author, the publish date and an honest updated date; Google's self-assessment asks whether you are "changing the date of pages to make them seem fresh when the content has not substantially changed".

The structured-data checklist

Google's position is that "structured data isn't required for generative AI search, and there's no special schema.org markup you need to add", and that it remains worth using for rich-result eligibility and entity clarity. The rule that governs all of it: markup must mirror the visible page.

Type Use it for Must match on the page Google status (Oct 2026)
Organization (or ProfessionalService/LocalBusiness) Who you are: name, url, logo (112 px minimum), sameAs, address, contactPoint, foundingDate, legalName The footer, About page and contact details No required properties; Google says some properties "are used behind the scenes to disambiguate your organization"
LocalBusiness Physical offices name and address required; telephone, openingHoursSpecification, geo, url, priceRange recommended Powers knowledge panel and Maps details
Article Every post author (Person with name and url or sameAs), headline, image, datePublished, dateModified in ISO 8601 with timezone Google "strongly recommend[s]" author url/sameAs; "all the authors that are presented as authors on the web page" must be in the markup; do not merge authors
ProfilePage Author pages mainEntity as Person with name; recommended description, image (no placeholders), sameAs, identifier; page dateCreated/dateModified "Designed for any site where creators (either people or organizations) share first-hand perspectives"
Service Service pages name, provider (your Organization), areaServed, serviceType, description No Google rich result; use for entity clarity and keep it consistent with the H1 and copy
FAQPage FAQ blocks Each question and answer visible, in the same words Rich result removed from Search on 7 May 2026; markup is harmless, the visible FAQ does the work
BreadcrumbList, WebPage, WebSite Navigation and site identity The breadcrumb trail and site name as shown Standard; already common

Three rules from Google's general structured-data guidelines, in its words: "Don't mark up content that is not visible to readers of the page"; "Items that are missing required properties are not eligible for rich results"; "Try to use the most specific applicable type and property names defined by schema.org for your markup". Validate with the Rich Results Test and the Schema Markup Validator after every template change; Google's generative-AI content guidance adds that structured data should be validated and fact-checked like any other output.

Freshness, feeds and discovery

  • Dates. Set datePublished once and dateModified only when the content substantially changes; Search Console shows AI feature clicks under the "Web" search type, so you can see whether refreshed pages gain impressions.
  • Feeds. Publish an RSS or Atom feed of new and updated posts so aggregators and tools that poll feeds see changes without recrawling the site. Google does not list a feed as a requirement for AI features; it is low-cost hygiene, like a sitemap.
  • Merchant Center and Business Profile. For products and locations, Google says these "can help your products and services to be visible in both AI responses and other Google Search results".
  • Internal links. Each page links up to its service page in the first 300 words and across to two related guides; Google lists findability "through internal links on your website" among the basics.

What not to do

  • Scaled or unreviewed AI text. Google's generative-AI content page (updated 1 October 2026) says "it is critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness before publishing" and that generating "many pages without adding value for users" may violate the scaled content abuse policy.
  • Invented authors or credentials. Google's helpful-content guidance warns against "deceptive authorship information". An author page must describe a real person who approved it.
  • Hidden or mismatched markup. An FAQPage the visitor cannot see, a Review for a review that does not exist, a Service with a different name from the H1.
  • Keyword stuffing. Below baseline in the only controlled study; a quality signal against you in Google's systems.
  • Chasing "AI text files". Search ignores llms.txt; keep one for other tools if you like, but it is not where the effort goes.

A page-by-page procedure

  1. Pick the ten pages that should win citations (services, the About page, the two best guides) and open each with the title's question in mind.
  2. Rewrite the first paragraph as the answer, 40 to 80 words, with the entity named.
  3. Find every claim and number; attach a source link or the method and date, or delete it.
  4. Add one table or one numbered procedure where the page compares or instructs; add a four-to-six-question FAQ with stand-alone answers.
  5. Add the byline, publish date, updated date and, where relevant, a line on how the page was produced.
  6. Generate or update Article/Service/Organization/ProfilePage markup from the visible content and validate it.
  7. Log the URL in the monthly citation panel (20 prompts, four engines, same day each month; see the GEO guide) and in Search Console, and review after the next crawl.

FAQ

Do I need special structured data for AI Overviews or ChatGPT?

No. Google states "there's no special schema.org structured data that you need to add" for AI Overviews or AI Mode, and no AI text files or Markdown versions. Standard Organization, Article and author markup that matches the visible page helps engines identify you; mismatched or hidden markup hurts.

Is FAQ schema still worth adding?

The FAQ rich result stopped showing in Google Search on 7 May 2026, so FAQPage markup no longer earns a visual result. A visible FAQ with 40-to-60-word answers is still worth writing because answer engines quote complete, self-contained sentences. Keep the markup only if it mirrors the visible text exactly.

What makes a sentence quotable by an AI engine?

It states one specific fact, names its source, and makes sense on its own without the surrounding paragraph. In the GEO study, pages with added quotations, statistics and cited sources gained the most visibility in generated answers, and keyword-stuffed pages lost visibility relative to the unoptimised baseline.

How important is the author byline?

Google strongly encourages bylines where readers expect them and warns against deceptive authorship. Its Article markup guidance recommends an author with a url or sameAs link, and ProfilePage markup describes author pages. Engines attribute more readily when a named person with a verifiable profile stands behind the page.

Should I split pages into short chunks for AI?

No. Google's guide says "there's no requirement to break your content into tiny pieces for AI to better understand it" and that "there's no ideal page length". Write complete pages with clear sections; engines extract the passages they need.
