🔥 SEOs Diners Club #215: Why Is AI Ignoring You? 98,000 Citation Rows Have the Answer

Hey everyone!

Two pieces of research dropped this week that could fundamentally change your AI search strategy. Kevin Indig analyzed 1.2 million ChatGPT responses and 98,000 citation rows on Growth Memo, answering "what does AI actually reward?" with hard data. Lily Ray and her Amsive team published a checklist of 70+ questions your website needs to answer so AI can accurately represent your brand.

When you combine these two studies, the picture is clear: AI citation isn't a writing quality problem. It's a content architecture problem.

In the same week, StatCounter data revealed a major shakeup in the AI search market, the first data from the March 2026 Google core update came in, and OpenAI announced conversational interactive ads in ChatGPT.

Grab your coffee. It's a packed one.

🎯 Headline: What 98,000 Citation Rows Tell Us

Your Opening Sentence Decides Everything

Kevin Indig's research on Growth Memo reveals one universal rule that holds across all 7 sectors studied (B2B SaaS, Finance, Health, Education, Crypto, HR Tech, Product Analytics): open with a direct, definitive statement.

Not a question. Not context-setting. Not a preamble paragraph.

"[X] is [Y]." or "[X] does [Z]." This format drives a 14% increase in citation rates across the board.

Pages that use hedging language in their openings ("this might help," "probably," "maybe") see lower citation rates. A page starting with "In this article, we'll explore X" is already behind in AI's eyes.

Let's look at concrete examples. These openings get skipped by AI:

Now, the openings AI actually cites:

Three features are common across every example: the first sentence states a fact (doesn't ask a question or set context), includes a specific number or named entity, and uses zero hedging language.

The other universal signal: dates and numbers. Publication dates combined with specific statistics form the most reliable citation signal pair. Adding a publication date to your pages and including at least one concrete stat in every piece of content works regardless of sector.

What Everyone Gets Wrong: Rules Change by Sector

Here's the truth the industry doesn't tell you: there is no universal "write like this and AI will cite you" formula.

Word count is a clear example. In B2B SaaS, longer content drives 1.59x higher citation rates. In Finance, shorter content wins (0.86x). Two sectors, working in completely opposite directions. As a general rule, pages under 1,000 words underperform in every sector, but the reward for length varies. In Finance, aim for 5,000–10,000 words. In Education, Crypto, and Product Analytics, go as long as possible. In B2B SaaS, focus on structure over word count.

Heading structure tells a similar story. For Crypto, 5–9 headings are optimal. For B2B SaaS, you need 20+. In Health, zero or a maximum of 5–9 headings perform best.

And perhaps the most surprising finding: 3–4 headings perform worse than zero headings in every single sector. This "3–4 heading dead zone" is universal without exception. Half-structured content confuses AI's navigation. Either fully structure your content or leave it unstructured. The middle ground is the worst option.

Question marks appear 2x more frequently in cited content. 78.4% of citations are linked to questions in headings. AI processes H2 headings as questions and the paragraphs beneath them as answers.

Entity Types: The Opposite of What You'd Expect

Entity findings also defy expectations. Big brand names registered in Google's Knowledge Graph are actually a negative signal (0.81x). Highly cited pages contain an average of 2.1 named entities versus 1.75 for low-cited ones. But the difference isn't quantity — it's quality: highly cited pages are packed with niche entities that have no KG registration at all. A specific methodology, a precise statistic, a named comparison. Specific knowledge wins, not general knowledge.

Price information is a negative signal in every sector except Finance. Pages that lead with pricing send a "commercial intent" signal, and AI categorizes them as sales pages rather than reference sources.

LinkedIn's Unexpected Power and the Reddit Reality

The platform-level findings are equally striking. 94.7% of all AI citations come from corporate content. Reddit and user-generated content are nearly invisible.

The "Reddit effect" disrupted organic search in 2024–2025. But that effect hasn't carried over to AI citations at the same scale. In Finance and Health, user-generated content has near-zero AI citation value. In Crypto, Product Analytics, and HR Tech, community content makes a measurable contribution, but still far below corporate content.

The real surprise is LinkedIn. Across ChatGPT Search, Perplexity, and Google AI Mode, LinkedIn ranks second in AI citations. LinkedIn content appears in 11% of responses. Semantic similarity scores range from 0.57 to 0.60, meaning AI reflects LinkedIn content nearly verbatim in its answers. Your LinkedIn content strategy is now critical not just for "visibility" but for AI citations.

What Does AI Know About Your Brand?

Lily Ray's "Branded Questions for AI Search Visibility Checklist," developed with her Amsive team, addresses exactly this. People are asking ChatGPT, Gemini, and Perplexity questions about your brand. For AI to answer correctly, those answers need to exist on your website.

The checklist covers 70+ questions across 10 categories: brand fundamentals (founding story, mission, values), brand identity and community (social media presence, events), products and services, pricing, security, support, sustainability, trust and reputation, and user experience.

At Stradiji, when we apply this list with our clients, the biggest gaps usually show up in "brand fundamentals" and "trust/reputation." There's an About page but it's three sentences. There are customer reviews but only on Google Business Profile, not on the website. AI looks at both sources, but it wants them on your site too. Consistency builds trust. If everyone says the same thing: trust. If one source says something different: silence.

Here's a practical test: open ChatGPT right now and ask "Is [your brand] trustworthy?" Look at the response. Is it accurate? Incomplete? Completely wrong? This test reveals your AI search visibility gaps in 30 seconds.

Mert's Take: Content Architecture Comes Before Writing Quality

The most important chart in this research doesn't show what you should do. It shows how much of the "universal" advice from the SEO/GEO/AEO industry falls apart in cross-sector analysis. Word count, list density, named entity count: flat or negative across the board.

But the universals are crystal clear: declarative opening sentences, publication dates, specific numbers, and sector-appropriate structure. Do you want to rank first in blue links, or do you want to be AI's trusted primary source? The answer to that question defines your digital strategy in 2026.

🔄 Algorithm and Search Engine Updates

March 2026 Google Core Update: First Data Is In

The March 2026 Google core update started rolling out on March 27. Estimated completion: around April 10–11. But the early data paints a striking picture.

JetDigitalPro's analysis of 600,000 web pages reveals:

Winners: Sites producing original data, first-hand case studies, expert commentary, and experience-backed content saw an average 22% visibility increase. Niche blogs, industry publications, and sites conducting their own research stood out.

Losers: AI-generated content produced at scale without human editorial oversight lost 60–80% of organic traffic. Affiliate sites took the hardest hit: 71% negative impact. Shallow comparison pages produced by swapping keyword templates saw 30–50% drops.

Information Gain scoring has become a primary ranking signal. Google now measures how much new information your content adds compared to existing top-ranking pages. Semrush Sensor volatility levels reached 8.7/10. 55% of domains tracked by Ahrefs showed 5+ position movements in at least one keyword cluster. This exceeds the turbulence of the August 2024 core update. The update hasn't finished rolling out yet — don't panic. Wait at least a week before analyzing Search Console data.

Major Shakeup in the AI Search Market

StatCounter's March 2026 data, published April 3, documented a significant turning point in the AI search market. Google Gemini climbed to second place in AI referral traffic with an 8.65% share. A year ago, that figure was just 2.31% — nearly 4x growth in 12 months. Perplexity, which peaked at 12.07% in April 2025, dropped to 7.07% by March 2026.

According to StatCounter CEO Aodhan Cullen, the reason is ecosystem advantage: Gemini is integrated into Google Search, Android, Workspace, and Chrome. ChatGPT still leads with 78.16%. But the most interesting movement comes from Claude: it jumped from 1.37% in February to 2.91% in March. It doubled its share in a single month — 10x growth over one year.

💰 AI Advertising: ChatGPT Talks, Google Sells

OpenAI x Smartly.io: Ads That Talk Back

OpenAI partnered with Smartly.io to develop conversational interactive ad formats in ChatGPT. This is a new format in digital advertising history: not a banner, not a sponsored link, but a dialogue that mimics the chat interface and responds to user questions. Initial optimizations target entertainment, retail, and sports brands.

Consider this alongside last week's $100 million ad revenue news. ChatGPT's ad pilot is only six weeks old, has 600+ advertisers, and self-serve access opens in April. The current $200,000 minimum commitment is being removed. Geographic expansion to Canada, Australia, and New Zealand is planned.

Google AI Mode: Ads in 25.5% of Responses

Google now shows sponsored results in 25.5% of AI Mode responses. A year ago, that figure was just 3% — a 394% increase. New ad formats for shopping and travel queries launched in April. Advertisers using Performance Max or AI Max for Search campaigns are automatically included in AI Mode. Early performance data: AI Mode ads drive 18% higher engagement than traditional search ads, but cost-per-click is 35% higher.

🤖 AI World

OpenAI Acquires TBPN: Entering Media

OpenAI acquired TBPN (Technology Business Programming Network) on April 2. The daily three-hour show, hosted by founders John Coogan and Jordi Hays on YouTube and X, has a cult following in Silicon Valley. According to the Wall Street Journal, the show is targeting over $30 million in revenue this year. OpenAI promised "editorial independence," but the show will report to the company's chief political operations officer, Chris Lehane. This signals that AI companies now want to control not just technology, but narrative and discourse.

Google Search Live Expands to 200+ Countries

Google expanded Search Live to 200+ countries where AI Mode is available. The feature, which launched only in the US and India in July 2025, is now global. The Gemini 3.1 Flash Live model supports natural voice conversation in 98+ languages. According to data Google shared with marketers, AI Mode queries are three times longer than traditional text searches. As voice and visual search go global, long-tail queries and natural language patterns become even more critical.

ChatGPT Comes to CarPlay

ChatGPT launched Apple CarPlay integration. You can start hands-free voice conversations in your car and continue existing conversations from the mobile app. AI assistants' "anytime, anywhere" strategy is becoming tangible.

👋 Closing

This week's core message is clear: AI citation isn't a writing quality problem. It's a content architecture problem.

Kevin Indig's 98,000 citation rows debunk most of the "universal" advice the industry has been selling. The true universals are few but powerful: declarative opening sentences, publication dates, and specific numbers. Everything else — from word count to heading structure — changes by sector. Lily Ray's 70+ brand questions show that AI visibility isn't just about "how do I write?" but "which questions about my brand does my website answer?"

Last week I summarized the formula as "AEO-compliant content structure + third-party credibility + cross-agent web readiness." This week, I'm adding to the formula: sector-specific content architecture + comprehensive brand question coverage + multi-platform visibility = the 2026 AI search formula.

If you want to adapt your SEO and GEO strategy to this new reality, we'd be happy to help at Stradiji.

See you next week. Take care!
