Why Top Data Aggregators Earned Zero AI Citations in New GEO Study
A groundbreaking study by ICODA and Semrush revealed that major data aggregators earned zero AI citations across 100+ queries in ChatGPT and Perplexity. Instead of structured directory listings, generative AI platforms favored narrative roundups, trade media, direct brand domains, and community forums. For small and local businesses, this research fundamentally redefines how to optimize for AI visibility.
Key Highlights
- ✓ICODA and Semrush tested 100+ controlled queries across ChatGPT and Perplexity, recording zero citations for top aggregator databases.
- ✓Conversational AI models preferred purpose-built editorial roundups over static data tables and directory listings.
- ✓Citations consistently concentrated across four pillars: narrative roundups, industry trade press, primary brand websites, and community discussions.
- ✓For businesses optimizing for AI search, passive directory listings must be replaced with editorial PR, comparison content, and organic forum presence.
What Happened
For years, standard digital marketing advice has urged brands to secure listings on top niche directories and data aggregators. In the crypto and Web3 space, that meant platforms like CoinGecko, CoinMarketCap, and DeFiLlama were considered the gold standard. Marketers assumed that if you gained verification on these centralized databases, conversational AI engines like ChatGPT and Perplexity would automatically trust and cite your brand.
A new comprehensive benchmark study conducted by growth marketing agency ICODA in partnership with Semrush just dismantled that premise entirely.
Researchers ran more than 100 controlled query runs across ChatGPT and Perplexity across four distinct user intent categories: recommendation-style searches ("best X in 2026"), breaking news events, safety and legitimacy checks, and community sentiment queries. The final tally? CoinGecko, CoinMarketCap, and DeFiLlama received zero citations. Not a single mention, link, or source credit was awarded to these multi-billion-dollar data hubs across the entire test suite.
Key Details: What AI Engines Actually Cite
The ICODA and Semrush audit revealed that AI engines do not rely on structured data tables when synthesizing conversational answers for end users. Instead of raw price feeds and database entries, the citations split cleanly across four specific source types:
- Purpose-Built Editorial Roundups: Platforms such as Coin Bureau and Datawallet dominated recommendation-focused queries. The study revealed that structural match beats raw domain authority every time. A narrative guide structured around "best solutions for 2026" directly aligns with how large language models (LLMs) synthesize answers, whereas tabular database records do not.
- Trade Press and Financial Media: When users inquired about safety, regulatory status, or breaking news, AI engines defaulted to established journalistic outlets rather than static directory profiles.
- First-Party Brand Websites: AI engines frequently bypassed intermediary listing sites to cite company primary websites directly when confirming core features, documentation, and foundational company data.
- Community Platforms: AI tools actively pulled unstructured consensus from social and community platforms like Reddit to answer qualitative questions about user sentiment and real-world reliability.
Crucially, only purpose-built editorial roundups achieved independent, cross-engine citation across both ChatGPT and Perplexity without coordinated distribution.
What It Means For Your Business
While this study focused on Web3 verticals, the behavioral mechanics of generative search engines are universal. Whether you are running a regional legal practice, a specialized B2B software consultancy, or a local service company, this research provides vital takeaways for your Generative Engine Optimization (GEO) strategy:
1. Directory Listings Are Necessary, But Insufficient
Local directories (like Yelp, YellowPages, or industry-specific registries) remain valuable for legacy local SEO and data verification. However, conversational AI platforms rarely cite them in competitive recommendation queries. Simply "existing" in a business database will not trigger an AI recommendation when a prospective customer asks ChatGPT: "Who is the most reliable commercial roofer in my area?"
2. Prioritize Narrative-Driven "Best Of" Roundups
LLMs generate responses synthetically by predicting narrative sequence. If your brand wants to appear when users ask for the "best" provider in your niche, you must earn inclusion in editorial listicles, comparison guides, and industry roundups. AI engines prioritize long-form, comparative context over raw address-and-phone records.
3. Build a Multi-Channel PR Footprint
Because AI engines look to third-party coverage for safety and trust verification, regular media coverage, guest thought-leadership, and independent reviews act as critical verification layers. Small business owners should shift a portion of their directory submission budgets toward local digital PR, podcast appearances, and trade press mentions.
4. Cultivate Real Community Sentiment
AI search tools increasingly crawl social forums to gauge authentic customer experiences. Fostering positive, organic discussions across platforms like Reddit, specialized forums, and Google Reviews ensures that when an AI models "sentiment," your brand is reflected as trustworthy, proven, and actively recommended by real humans.
Why This Matters For Your Business
For small and local businesses, this research fundamentally changes the playbook for Generative Engine Optimization (GEO). Many businesses mistakenly believe that paying for inclusion in dozens of online business directories, aggregator networks, or industry databases will automatically make them visible in ChatGPT, Gemini, or Perplexity. This study provides empirical proof that AI models do not cite passive data aggregators when responding to user recommendations. Instead, AI search platforms look for qualitative, context-rich narratives that directly answer natural-language questions. When a potential buyer asks an AI engine for advice, the model seeks out balanced comparison articles, credible local news mentions, and authentic community discussions. Businesses relying solely on legacy NAP (Name, Address, Phone) citation building are essentially invisible in the next generation of conversational search. To build sustainable AI visibility, small business owners must transition from simple data syndication to holistic digital authority. That means getting featured in regional roundups, maintaining rich explanatory content on their primary website, and building genuine reputation signals across third-party media and social channels.
Frequently Asked Questions
Why did major aggregators get zero citations in AI search results?
AI engines prioritize content that structurally matches natural-language prompts. Data aggregators primarily host tabular price feeds, directory records, and raw metrics, whereas AI models seek synthesized editorial context, comparative analysis, and explanatory text to construct answers.
Should small businesses stop building directory listings entirely?
No. Directory listings and NAP citations remain important for traditional Google Maps rankings, local crawling, and basic entity validation. However, they can no longer be your primary strategy for AI search visibility, which demands editorial mentions, press coverage, and detailed web content.
How can a local business get cited in AI roundups and conversational results?
Focus on earning placement in local lifestyle blogs, chamber of commerce guides, and industry comparison articles. Additionally, publish comprehensive service comparison pages on your own website, secure authentic customer reviews on community platforms, and invest in localized digital PR.
