Executive summary

AI models decide whether to cite your page in two stages. First, retrieval: does the page get pulled into the model’s context window when a buyer asks a relevant question? Second, citation: given that the page is in context alongside competing sources, does the model choose yours to quote and link? Most content fails at both stages because it was written for Google’s ranking algorithm, not for extraction by a language model. This guide covers the 18 on-page factors that influence both stages, organised by impact: what the content says (makes or breaks citation), how it is structured (retrieval signals), and what to avoid (patterns that get you filtered out).


Quick reference: 18 factors at a glance

The first eight factors determine whether the model cites your page or a competitor’s. These are the content-level signals.


01. Lead with a direct answer

When an AI model pulls your page into its context window, it scans for a passage that directly answers the query. If the answer is buried after three paragraphs of context-setting, the model may extract a passage from a competing page that answers immediately. The fix is structural: put a usable answer in the first 200 words.

This does not mean dumbing down the content. It means stating the conclusion first, then supporting it. A page about implementation timelines should open with “Implementation typically takes 8-12 weeks for a mid-market company, depending on data migration complexity and integration requirements” before explaining each phase. The model can extract that sentence as a citation. It cannot extract “In this article, we explore the many factors that affect implementation timelines.”

If your page is long-form, add a TL;DR block at the top that summarises the core argument in 2-3 sentences. Mark it with speakable schema so AI models know this passage is designed for extraction. The TL;DR and speakable work together: the TL;DR gives the model a cite-ready passage, and speakable tells it this passage was written for that purpose.

Before

“In today’s rapidly evolving business landscape, choosing the right platform is more important than ever. Many organisations struggle with this decision. In this comprehensive guide, we explore the key factors to consider...”

After

“Mid-market companies (50-500 employees) evaluating core HR platforms should prioritise three criteria: data migration support, payroll integration depth, and compliance coverage for their operating jurisdictions. Here is how to evaluate each.”


02. Write extractable passages

AI models cite by extracting a passage (typically 1-3 sentences) and attributing it to the source. If your key claims are spread across multiple paragraphs and require the reader to synthesise them, the model has to paraphrase. Models prefer not to paraphrase when a clean extractable passage exists on a competing page.

The test: can you highlight a 1-3 sentence passage in each section that makes a complete, specific claim without requiring context from surrounding paragraphs? If yes, the section is extractable. If every claim needs the preceding paragraph to make sense, rewrite the claim as a standalone assertion and let the surrounding text provide supporting detail.

Paragraph length matters here. Walls of text (paragraphs longer than 6 sentences) make extraction harder because the model cannot isolate the claim from the padding. Single-sentence paragraphs create the opposite problem: no context around the claim. The sweet spot is 2-4 sentences per paragraph, with each paragraph making one point.


03. Be a primary source

When multiple pages answer the same question, AI models prefer primary sources over derivative restatements. A page that presents original data (“we surveyed 200 companies and found...”), original synthesis (“combining these three datasets reveals...”), or an original argument (“the industry assumption that X is true is wrong, and here is why...”) is more likely to be cited than a page that restates what other sources already say.

This is the highest-leverage single factor. If your page is derivative (if someone else published the same information first and your page adds no new data, no new analysis, and no new position), it will struggle to earn citations regardless of how well it is structured. The question to ask before publishing is: what does this page contain that does not exist anywhere else? If the answer is “nothing,” the page needs original evidence or an original perspective before it is worth optimising for anything else.

Content types that naturally carry originality: market reality reports (original data from your industry analysis), trust stories (original narrative from a real customer), criteria flips (original argument backed by market data), decision frameworks (original methodology). Content types that risk being derivative: generic how-to guides, listicles sourced from other listicles, product comparison pages that repeat spec sheets.


04. Use numbers with units

Numbers with units are the densest form of evidence a page can carry. “37% of buyers cited implementation cost as their primary concern” is citable. “Many buyers worry about implementation cost” is not. AI models extract specific claims because specific claims are useful to the person asking the question. Vague claims are not useful, so they are not extracted.

The threshold is practical: a page under 500 words needs at least 3 numeric claims to signal density. A longer page (1,500+ words) should aim for 6 or more, distributed across sections rather than clustered in one table. Each number should include its unit and context: not “37%” alone, but “37% of mid-market buyers in Q1 2026.” The context turns a statistic into an extractable fact.


05. Date your claims

A claim without a date is a claim without a shelf life. AI models weigh recency: a statistic from Q1 2026 competes better than an undated statistic that might be from 2019. When you state a fact, tie it to a time frame. “In Q3 2025, the average implementation timeline was 11 weeks” is extractable and verifiable. “The average implementation timeline is around 11 weeks” is extractable but undatable, which means the model may deprioritise it in favour of a competing source that does date its claims.

Dated claims also age honestly. When a reader (or a model) sees “as of March 2025,” they can assess whether the data is still relevant. Undated claims pretend to be timeless but are actually stale in ways nobody can detect. Date your claims and update them when the data changes.


06. Name your evidence

“Studies show” is not evidence. “A 2025 Gartner survey of 1,200 IT decision-makers found” is evidence. Named Named entities (organisations, published studies, named researchers with credentials, specific products) function as verifiable anchors. AI models can cross-reference named entities against their training data. Unnamed claims cannot be verified and carry less weight.

When citing a source, include the entity name, the date, and a short description of the methodology or scope. When referencing a product, use its proper name rather than a generic category. When quoting a person, include their title and organisation. Each named reference makes the passage more extractable because it adds verifiable specificity.


07. Show your methodology

If your page makes empirical claims (market statistics, comparative analyses, survey results, benchmark data), include a methodology section. This does not need to be academic-level rigour. It needs to answer: what did you measure, how did you measure it, what was the sample, and what are the limitations?

A methodology section does two things for AI citation. First, it signals that the data is original (see factor 03). Second, it gives the model a way to evaluate the credibility of the claims. A page that says “we analysed 63 buyer scenarios across 6 AI models using prompts derived from real buyer questions” carries more weight than a page that presents the same data without explaining where it came from. For content types that do not make empirical claims (opinion pieces, how-to guides, narrative case studies), this factor does not apply.


08. Publish with a credentialed byline

A page with no author is a page with no accountability. AI models weigh author authority as a trust signal, particularly for topics where expertise matters: technical guides, financial analysis, health information, legal guidance. A byline with topic-relevant credentials (“Flemming Rubak, founder of Seedli and former Head of Digital at [company]”) is stronger than a byline alone (“by Flemming”), which is stronger than no byline at all.

In schema markup, use sameAs on the author entity to point to multiple verifiable profiles: LinkedIn, a personal website, conference speaker pages, published articles on other platforms. This gives AI models a way to confirm that the author exists, has relevant experience, and has published on the topic elsewhere. A single sameAs link to LinkedIn is useful; three links across different platforms build a stronger entity signal.

"author": {
  "@type": "Person",
  "name": "Flemming Rubak",
  "sameAs": [
    "https://www.linkedin.com/in/flemming-rubak/",
    "https://www.seedli.ai/about"
  ]
}

The content-level factors determine whether a model cites you. The structural factors determine whether it finds you in the first place.


09. Build a heading hierarchy AI can parse

AI models use your heading hierarchy as a navigational index. A flat list of vague H2s (“Introduction,” “Overview,” “More Info”) forces the model to read the entire page to find the relevant section. A structured hierarchy with descriptive headings lets it jump to the right section, extract the answer, and cite the source.

Three rules: H2s should be descriptive enough to stand alone as section titles. H3s should use buyer language (the actual words buyers use when asking questions). The hierarchy should be logical (no H4 before an H2, no skipped levels). Each heading should function as a self-contained label that tells the model what the section covers without reading the section.

10. Make sections self-contained

AI models do not always read your full page. They may extract a single section, the one that best matches the query, and cite it in isolation. If that section starts with “As mentioned above” or refers to a concept only defined three sections earlier, the extracted passage does not make sense on its own and the model will prefer a competitor’s page where the section is self-contained.

The self-containment test: pick any section from your page and read it without reading anything before or after it. Does it make a complete, understandable claim? If it requires context from elsewhere on the page, rewrite it so the essential context is included in the section itself. This does not mean repeating everything. It means ensuring each section states its own premise before presenting its conclusion.


11. Use descriptive URLs

When AI models retrieve search results, the URL is part of the metadata they evaluate for relevance before reading the page content. A URL like /guides/consolidating-from-point-solutions tells the model what the page covers. A URL like /guides/guide-47 does not.

The URL slug should mirror the buyer’s language: the words they would use when asking the question your page answers. Include the situation or topic, not just the product category. “/comparisons/hubspot-vs-salesforce-for-mid-market” is stronger than “/comparisons/crm-options.” The URL is a second title that AI models read when deciding whether to retrieve your page.


12. Write meta descriptions for AI, not just Google

Google truncates your meta description at 155 characters. AI models read every word. Write the first 155 characters for the search engine results page, then continue to 300 characters with the specific claims, data, and position that AI needs to evaluate whether your page is worth pulling into context. The extended portion is invisible on Google but fully visible to AI retrieval.

13. Add schema as a context layer

Most schema advice optimises for Google rich results: FAQ, HowTo, breadcrumbs. There are schema types Google ignores that AI models parse as structured context. DefinedTerm tells models the page defines a concept. Speakable tells them which passage is designed for extraction. About and mentions tag the entities the page covers. Claim (ClaimReview) attaches verifiable assertions to your content.

Schema is not a ranking factor in the traditional SEO sense. It is a context layer that helps AI models understand what your page is about, what it claims, and how authoritative those claims are. Think of it as metadata that reduces the model’s interpretation work.

14. Tell AI your content is current

A publication date tells AI models when you wrote the content. A dateModified value tells them when you last confirmed it is still true. Without dateModified, a page published in 2024 looks stale by 2026 even if the content is still accurate. With dateModified set to the last review date, the same page signals active maintenance.

Add visible temporal markers in the body text too: “Last verified April 2026” or “Updated with Q1 2026 data.” These give the model a second freshness signal beyond the schema. Plan a review cadence for evergreen content: quarterly for market-facing pages, biannually for process documentation. Update dateModified with each review.

15. Design internal links as a knowledge graph

AI models do not crawl your site the way Googlebot does. They read your link structure as a topical authority map: which pages connect to which, and what the anchor text says about the relationship. A page with five contextual internal links to related content signals comprehensive coverage. A page with no outbound links signals an isolated piece with no supporting evidence on your own domain.

Link less, but link better. Every internal link should carry descriptive anchor text that explains the relationship: “the decision framework that defines how buyers compare providers” rather than “click here.” The anchor text is what tells the model why the linked page is relevant.

The structural factors get your page into the model’s context. The content factors get it cited. The final section covers the patterns that get you filtered out entirely.


What not to do

These patterns reduce citation likelihood. Some are inherited from SEO-era habits. Others are caused by AI-generated content tools that optimise for word count rather than evidence density.

16. Don’t hedge without sources

“Studies show,” “experts agree,” “many believe,” “it is widely known.” Every one of these phrases is a claim without a source. AI models treat unsourced hedged claims as low-confidence assertions. If you have the source, name it. If you do not have the source, either find one or remove the claim. Six or more vague claims on a single page is a signal that the content is not evidence-based.

17. Don’t write marketing copy where evidence belongs

“Best-in-class,” “industry-leading,” “revolutionary,” “our solution delivers unparalleled results.” Promotional language without supporting evidence is not citable. AI models skip superlatives because they add no information. The test: if you remove the adjective and the sentence loses its meaning, the sentence was making a claim it could not support. Replace superlatives with specific evidence: “industry-leading” becomes “ranked first by Gartner in 2025 for mid-market implementations.”

18. Don’t gate your content or publish AI filler

Content behind a paywall or login gate does not get retrieved. Content that requires JavaScript to render may not get indexed. Both are retrieval blockers that prevent your page from entering the model’s context window in the first place. If the content needs to earn citations, it needs to be publicly accessible in static HTML.

AI-generated filler is the other filter. Repetitive sentence structures, generic examples, lists of synonyms padding word count, and openers like “In today’s fast-paced world” all signal content that was generated for volume rather than substance. AI models appear to deprioritise obviously AI-generated content. The mechanism is not publicly verified, but the pattern is observable: pages with original analysis outperform pages with generated filler on the same topic.

Also avoid

Keyword-stuffed H2s on every section (“Best CRM Software: Why Our CRM Software Is the Best CRM Software”). Tacked-on FAQ sections that restate the body text as questions. “AI-optimized” meta tags that read like spam. These patterns are not neutral. They actively reduce citation likelihood because they signal low-quality content to models trained on billions of pages.

A note on what this guide does not cover

These 18 factors are on-page signals. They determine what you can control. Off-page factors (domain authority, backlink profile, brand mentions across the web, and actual retrieval behaviour by specific AI models) also affect whether your page gets cited in practice. This guide focuses on the on-page factors because they are the ones you can change today.
