As an observer in the AI SEO field, I've been closely following the debate about 'how to optimize content for AI.' Some experts insist on specific GEO tactics like 'content chunking,' while others believe 'good content certified by E-E-A-T' is sufficient. But what does the data actually tell us? Early research and experiments (including Otterly's latest AI citation report) give us a glimpse into what content chosen by ChatGPT, Perplexity, and Google AI Overviews has in common. The conclusion: many classic SEO best practices still work, but new tactics specifically for Generative Engine Optimization (GEO) have emerged.

Key Takeaways

Technical SEO remains critical: crawlability, pure HTML, and fast response times determine if AI can access your content

Content structure matters more than ever: Q&A format, clear heading hierarchy, lists, and tables make content easier for AI to chunk and cite

Readability is a top-3 ranking factor: Flesch reading scores directly correlate with AI citation rates

E-E-A-T signals influence AI just as they do traditional search: expertise, authority, and trust remain paramount

Recency bias is real: AI models strongly prefer fresh content, with cited pages averaging 25% newer than traditional search results

Context over keywords: LLMs perform 'query fan-out,' seeking sources that cover complete topic contexts, not keyword matches

AI Search Ranking Factors (Data Edition)

Before diving into details, here's a quick reference table showing what factors drive AI's choices:

Ranking FactorEffective TacticsWhy It Matters
Technical SEOCrawlability, pure HTML (not JS-dependent), extremely fast responseIf AI crawlers can't read your content, they can't learn from or cite you
Content StructureQ&A format, clear heading hierarchy, lists, tablesStructured content is easier for AI to 'chunk' and extract citations from
ReadabilityConcise answers, simple language, clear concept connectionsAI models need to quickly understand concepts and extract answers; complex sentences are their enemy
Authority (E-E-A-T)Expert signals, information gain, unique insightsAI tends to cite sources it considers 'trustworthy,' consistent with Google's traditional standards
Content FreshnessFrequent updates to important pagesAI models show clear 'recency bias,' favoring the latest information
Semantic RelevanceFocus on context over keywords; optimize entitiesAI doesn't look at keyword matching; it looks at whether you satisfy the complete intent behind queries

1. Make It Extremely Easy for AI Bots to Access Your Content

Googlebot and LLM crawlers (like GPTBot) scan the internet for two main purposes: training models or providing data for real-time search. If these bots can't get in or can't understand your content, you're out. Simple as that.

Action Points:

  • Embrace Pure HTML: Data shows nearly half of ChatGPT bot visits start in 'reader mode'—pure HTML versions without CSS or JS. If your core content depends on JavaScript loading, AI likely can't 'see' it at all.
  • Optimize Page Speed: Response time is an extremely strong visibility factor in AI search. Faster-loading pages are more likely to be included in LLM's real-time answers.
  • Fix Technical Issues: 4XX/5XX errors, incorrect robots.txt rules, CDN blocking—these are common reasons AI crawlers 'bounce.'
  • Internal Linking: Strong internal link structure helps bots discover deep pages and understand topical relationships between content.

Case Example:

A SaaS client faced severe redirect chains and orphaned page issues, resulting in extremely low AI crawl rates. After fixing these basic technical SEO problems and simplifying HTML structure, their brand's citation rate in AI search results surged 220% within 6 months.

2. Restructure Content for AI Parsing

LLMs (like ChatGPT, Gemini) read content differently than humans. They break pages into smaller chunks and evaluate each chunk's value independently. This means your content structure must facilitate AI 'chunking' and 'citation.'

Research finds that Q&A format performs best in GEO because it has the highest semantic relevance to user queries.

Action Points:

  • Clear Heading Hierarchy: Strictly use H1, H2, H3.
  • Question-Oriented Headings: Directly use users' actual search queries as H2 or H3.
  • Direct Answers: Follow headings immediately with concise, direct answers (30-50 words).
  • Use Lists and Tables: AI strongly prefers structured data. If you can say it with a table, don't use paragraphs.

Case Example:

Compare Ahrefs' blog articles—you'll find they extensively use 'question + direct definition' structure, which has given them dominance in AI answers for 'what is...' queries.

3. Pursue Extreme Readability and Clarity

According to Growth Memo's research, Flesch reading scores (readability) are among the top three factors determining whether content gets cited by AI. Simply put: Can AI bots extract information effortlessly? If not, they move to the next page.

AI doesn't reward flowery rhetoric—it rewards clarity.

Action Points:

  • One Heading, One Point: Don't cram multiple topics into one paragraph.
  • Inverted Pyramid Structure: Give the conclusion first, then expand on details.
  • Speak Human: Use simple, direct descriptions instead of industry jargon.
  • Shorten Paragraphs: Keep paragraphs to 2-4 lines. This reduces cognitive load and makes it easier for AI to extract core ideas.

Example:

❌ Don't Beat Around the Bush: 'User-generated content is becoming increasingly important in the digital realm. Many brands are seeking new ways...' (too much fluff)

✅ Direct Answer: 'What is User-Generated Content (UGC)? User-generated content is any content created by consumers rather than the brand itself, such as photos, videos, reviews, or social posts.'

4. Demonstrate E-E-A-T (Not Just Talk About It)

Google executives have explicitly stated that E-E-A-T (Experience, Expertise, Authority, Trust) signals affecting traditional search also influence AI Overviews. AI tries to mimic human preferences: we'd rather hear advice from people with real experience than from parrots.

Action Points:

  • Share Real Experience: Describe what you actually did, tested, and learned.
  • Cite First-Party Data: Publish your own research reports or customer data.
  • Expert Testimonials: Quote recognized industry experts in articles to establish 'co-citation' relationships.
  • Author Credentials: Display author expertise and credentials prominently.
  • Update Dates: Show 'last updated' timestamps to signal freshness and maintenance.

5. Keep Content Fresh (Recency Bias)

Countless AI SEO studies show AI models have strong 'recency bias.' Ahrefs data shows pages cited in AI search are on average 25% fresher than pages ranking in traditional search.

Seer Interactive's research also found that the vast majority of sources cited by ChatGPT and Perplexity were published within the last two years.

Action Points:

  • Update Rather Than Create New: Don't write new articles just to update—instead, refresh old articles that once ranked well but have declined.
  • Add Timestamps: Explicitly mark 'last updated' dates.
  • Replace Old Data: Swap 2023 statistics with 2025 data.
  • Seasonal Refresh: Update time-sensitive content quarterly or annually.
  • Content Audit: Regularly review and refresh your top-performing pages.

6. Focus on Context, Forget Keywords

Old SEO was about keyword matching. That era is over. Modern LLMs perform 'query fan-out': they expand users' brief questions into networks of related intents and sub-topics, then seek sources covering these sub-topics.

If you want to be cited, you need to cover the complete topic context, not stuff keywords.

Action Points:

  • Collect Real Questions: Use People Also Ask (PAA), Reddit, Quora, or social media comments to find what users actually care about.
  • Fill Semantic Gaps: Add FAQ sections at article ends specifically answering long-tail, specific sub-questions.
  • Entity Optimization: Use Schema markup to clearly define entities (people, products, companies, places) in your content.
  • Topic Clusters: Build comprehensive topic clusters that cover all aspects of a subject.

Case Example:

Oriel Partners' article about 'working in Saudi Arabia' was cited 17 times by Google AI Overviews. The secret: they didn't just write generic advice—they specifically mined Reddit for pain points expats care about and answered each one in the article.

Frequently Asked Questions

Is GEO different from traditional SEO?

GEO (Generative Engine Optimization) builds on traditional SEO but adds AI-specific tactics. While technical SEO, E-E-A-T, and quality content remain important, GEO emphasizes content structure (Q&A format, chunking), extreme readability, recency bias, and semantic context over keywords. Think of GEO as SEO evolved for AI consumption rather than human browsing.

What's the most important factor for AI citations?

No single factor dominates, but if forced to choose, **content structure** (Q&A format, clear headings, lists/tables) combined with **technical accessibility** (pure HTML, fast loading) are the foundation. Without these, even the best content won't be parsed and cited by AI. Readability (Flesch score) is the third critical factor—AI can't cite what it can't quickly understand.

How often should I update content for AI search?

AI models show strong recency bias, so update frequency matters. For evergreen content, refresh quarterly with new data, examples, and timestamps. For trending topics, update monthly or even weekly. Focus on updating high-performing pages that have declined rather than constantly creating new content. A well-maintained library of 50 updated articles outperforms 200 outdated ones.

Do I need Schema markup for GEO?

While not strictly required, Schema markup significantly helps AI understand your content's structure and entities. Implement FAQ schema, HowTo schema, Article schema, and Organization schema at minimum. Schema acts as 'labels' that help AI quickly identify and extract relevant information, increasing citation probability by 2-3x according to early studies.

Can I optimize for both traditional SEO and GEO simultaneously?

Absolutely—and you should. The core principles overlap: technical excellence, quality content, E-E-A-T, and user intent. The main additions for GEO are: 1) Restructure content into Q&A format with direct answers, 2) Prioritize readability over eloquence, 3) Update content more frequently, 4) Focus on topic context over keyword density. These changes actually improve traditional SEO too.

Conclusion

The SEO game has changed in 2026. We're no longer trying to trick algorithms—we're trying to become the clearest, most authoritative, freshest answer provider in AI's eyes. Even if you only have energy for one thing, remember this: Make your content structured, direct, and machine-readable. That's the core of GEO. The brands that adapt fastest to AI consumption patterns will dominate the next decade of search visibility.
