How to get cited by LLMs: Why Proprietary Data is the New SEO/GEO Superpower

In the era of AI-driven search, the goal of content marketing is growing once again to rank not only on search engines and social media but also being the cited source for an AI response.

Whether it’s ChatGPT, Claude, or Google’s AI Overviews, these Large Language Models (LLMs) have a specific appetite for proprietary data.

According to Semrush, optimizing for AI search requires a shift toward “Information Gain.” When you provide unique, original research that doesn’t exist elsewhere, you become the definitive source that the AI must cite to remain accurate.

But it’s not just the AI that wants this data. New consumer research from Pollfish shows that your audience is craving original data backed content too.

Why LLMs Prioritize Original Research

LLMs are trained to prioritize high E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness). Proprietary data is the best way to achieve all of this.

When you publish a study using original survey data, you establish yourself as a primary source.

• Unique Factoids: AI models look for specific numbers to answer user queries. If you are the only one who knows that “62% of [insert your target audience] prefer X,” the AI has to point to you.
• Reduced Hallucination: Models are being fine-tuned to prefer “grounded” data. Citing a specific study makes the AI’s response more reliable, which is why proprietary data is mentioned by Semrush as a key pillar of AI optimization.

The Consumer Connection: Trust and Clickability

Data-driven content doesn’t just please the algorithms. It also wins over humans. Our recent Pollfish study of 1,000 content consumers revealed exactly how much weight original data carries in the eyes of your audience.

1. Data Builds Trust

When we asked consumers what makes them trust an article, 62.5% of respondents said that “it cites a study or includes proprietary data.” In a world of AI-generated “fluff,” hard numbers act as an anchor of credibility.

2. Headlines with Data Wins Clicks

Your headline is your first (and sometimes only) chance to grab a reader. Our data shows that 53.2% of consumers find “specific, narrow original findings” to be the most clickable type of headline– beating out personal anecdotes, exclusive interviews, and even “unusual or surprising” claims.

3. Data Strengthens Brand Authority

The impact of data lasts long after the reader finishes the article.

• 88% of consumers say that seeing a specific study or data point makes them trust a brand more (“Definitely” or “Possibly”).
• 52% are “much more” or “somewhat more” likely to trust a brand specifically if their article contains original research.

How PR and SEO Professionals Can Use Proprietary Data Today

If you are a PR pro or an SEO writer, your goal should be not only a “content creator” but also a “data provider.”

1. Stop Curating, Start Originating: Instead of writing “10 Trends in [your audience],” run a Pollfish survey to find out which of those 10 trends consumers are actually investing in and how if they think it’s worth it.
2. Optimize for the “Snippet”: When you get your survey results, create “Data Nuggets.” These one-sentence takeaways are easy for an LLM to scrape and cite
   • Example: “According to a Pollfish study, 53% of consumers prefer data-backed headlines over clickbait.”
   • Bonus tip: These also make for great campaign assets that can be used in social campaigns. Check out our blog on creating a data backed content calendar
3. Create “Cite-able” Assets: Use charts and graphs. While LLMs are primarily text-based, multimodal models (like GPT-4o) are “reading” images to extract data.

Conclusion: Future-Proof Your Content

The “Information Gain” era of SEO is here. As AI continues to synthesize the web, the only way to remain relevant is to provide the ingredients the AI needs to generate its answers.

Proprietary data is the secret ingredient that builds trust with your human readers, earns clicks from your target audience, and makes your brand the indispensable source for the AI engines of tomorrow.
