Wellows AI Citation Study: 9,471 Prompts Impact Search Rankings

What Happened

In a first-of-its-kind research initiative, Wellows—an AI-focused data analytics firm—has published an extensive citation study based on 9,471 prompts submitted to popular generative AI platforms, including ChatGPT, Perplexity, Gemini, and Google AI Overviews. This study, featured by USA Today, examines which businesses are cited in AI-generated responses and the frequency of those citations.

Key takeaways include:

• Prompt diversity: The dataset encompasses a broad spectrum of queries, from “best coffee shop near me” to “how to fix a leaky faucet.”
• Platform variance: Each AI model exhibits unique citation preferences, with Google AI Overviews favoring structured data while ChatGPT relies more on recent web content.
• Local advantage: Small, locally optimized businesses appear 34% more often than larger, less targeted ones when the prompts include geographic indicators.
• Citation quality: Businesses that utilize structured schema markup and maintain NAP consistency (Name, Address, Phone) enjoy a 2-3× increase in AI visibility.

The methodology of the study involved inputting the same set of prompts across each AI tool, capturing the top three cited sources, and cross-referencing these with a proprietary business database. This approach resulted in a detailed map illustrating how AI engines select which businesses to highlight.

Key Details

| Metric | ChatGPT | Perplexity | Gemini | Google AI Overviews |

|--------------------------------|---------|------------|--------|----------------------|

| Avg. citations per prompt | 1.8 | 2.1 | 1.9 | 2.4 |

| Local business citation rate | 28% | 31% | 30% | 38% |

| Structured data impact | +15% | +18% | +16% | +27% |

| Top-cited sector | Restaurants | Home Services | Health & Wellness | Retail |

Why the numbers matter: The elevated citation rate for Google AI Overviews indicates that Google’s AI is significantly influenced by its own search index and schema-rich pages. Conversely, ChatGPT’s lower local citation rate suggests a heavier reliance on broader web content, emphasizing the need for content freshness and authoritativeness.

The Prompt Breakdown

• Transactional queries (e.g., “order pizza near me”) yielded the highest local citation frequency at 42%.
• Informational queries (e.g., “how to start a garden”) revealed a modest local citation rate of 22%, suggesting that AI tools still prioritize encyclopedic sources.
• Navigational queries (e.g., “open 24-hour pharmacy in downtown”) generated the most consistent NAP-rich citations across all platforms.

What It Means For Your Business

1. Optimize for Structured Data

If you haven’t done so already, implement Schema.org markup for your business (LocalBusiness, Product, Service, FAQ). The study indicates a 27% lift in citations on Google AI Overviews when structured data is utilized, making this the most impactful technical enhancement you can apply.

2. Prioritize Local SEO Signals

• Google My Business (now Business Profile): Ensure your information is current and accurate, as AI tools utilize this data.
• Maintain NAP consistency across your website, directory listings, and social media profiles to minimize friction for AI citation algorithms.
• Create geo-targeted content (such as city-specific landing pages and blog posts) to significantly increase your chances of being cited in location-based prompts.

3. Create Fresh, Authoritative Content

AI platforms like ChatGPT favor recent, authoritative pages. Consider publishing monthly blog updates, case studies, and customer testimonials that address the specific phrasing identified in the study’s prompts.

4. Leverage User-Generated Content (UGC)

Encourage reviews, Q&A sections, and community forums that feature naturally phrased language mirroring real-world prompts. This practice helps AI models better align your business with user intent.

5. Monitor AI Citation Trends

Utilize tools like VisibilityAI to set up alerts for your brand name in AI-generated responses. Monitoring where and how often you are cited allows for near-real-time adjustments to your SEO strategies.
