Introduction

Quick clarifier: “model citations” here means the sources AI assistants (e.g., ChatGPT, Google’s AI Overviews, Perplexity) name or link in their answers. This is different from academic citations in research papers. In AI relations, the goal is to be referenced by the assistant at the moment of intent—inside the answer itself.

Examples of assistant citations: Google AI Overviews showing a small set of sources; Perplexity’s inline “Sources” beneath answers; ChatGPT footnotes or links in browse modes. See observed source patterns in independent analyses from Amsive and others for ChatGPT, Google, and Perplexity (Amsive findings; Perplexity overview).

“Model citations” are the mentions, links, and attributions that AI answer engines include when they generate responses. In AI relations, winning model citations means your brand or content is named and/or linked inside the answer box, chat reply, or footnotes—so prospects hear your story even when they never click through to a SERP.

Why this matters now:

• A growing share of queries end in zero clicks as AI answers and summaries dominate results, shrinking traditional SEO traffic. Multiple analyses show meaningful click‑through declines when AI answers appear. Unusual on zero‑click trends. Amsive on AI Overviews CTR impact and source patterns.

• Brands cited by models capture attention and trust at the moment of intent—often with higher downstream conversion than classic organic. Amsive’s analysis of which sources engines cite most.

What counts as a model citation

A model citation can be any of the following inside an AI answer:

• Inline source link (e.g., Perplexity’s “Sources” cards beneath each answer). Perplexity overview.

• Footnote or reference list (common in ChatGPT browse modes) pointing to your domain or a third‑party page that features your brand. Amsive source distribution.

• Branded mention (your company name) inside the AI text, with or without a link, that positions you as a recommended solution.

• Overview “source” tiles (e.g., Google’s AI Overviews) that include your URL or an article that features you. Amsive data on AI Overviews.

Engine behaviors to know

• ChatGPT (OpenAI): Frequently cites high‑authority, broadly trusted domains; analyses show heavy weighting toward Wikipedia and Reddit among others. Implication: corroborating evidence on community and reference hubs increases your odds of being named when users prompt for vendors or how‑to guidance. Amsive source breakdown.

• Google AI Overviews: Shows a compact answer with a small set of sources; data indicates an outsized pull from Reddit, YouTube, and Q&A communities. Implication: authoritative, up‑to‑date explainers (yours and third‑party) plus credible discussion threads can drive inclusion. Amsive AI Overviews findings.

• Perplexity: Designed around real‑time research with visible citations inline; answers typically list multiple sources and encourage drilling down. Implication: information‑dense, clearly structured resources are highly discoverable and citable. Perplexity overview.

How Unusual measures and reports model citations

Unusual is the first AI relations platform—PR for AI—that shows how models think and talk about your brand, then takes action to fix gaps. Capabilities include:

• Per‑engine visibility: Track bot crawls and mentions from different AI models and monitor competitor coverage over time. Unusual product.

• Source graph intelligence: Identify the third‑party domains models rely on for your topics (e.g., Reddit, Wikipedia, major media) and prioritize earned coverage accordingly. Unusual’s source identification.

• AI‑optimized owned content: Generate and host an AI‑readable, information‑dense version of your site on a subdomain (e.g., ai.example.com) built for models—not humans. Unusual AI pages.

• Performance tracking: Quantify how content changes increase your mentions and model citations—and how those mentions correlate with demos and revenue. Book a demo.

How to earn model citations (AI relations playbook)

1) Publish AI‑readable owned assets

• Stand up an AI‑optimized subdomain with structured, citable, Q&A‑style pages that answer buyer questions directly, embed canonical facts, and resolve brand/entity ambiguity. Unusual AI pages.

2) Win the model’s source graph

• Secure coverage on the domains each engine cites most for your topics (e.g., Wikipedia entries with strong sourcing, high‑signal Reddit threads, authoritative explainers, reputable media). Amsive source distribution.

• Provide quotable, evidence‑based content that third parties want to reference.

3) Get your technical signaling right

• Ensure models can crawl your AI subdomain; avoid interstitials that block bots.

• Add structured data and clear headings so answers are extractable; consider emerging llms.txt guidance to point models to canonical resources. Technical best practices.

4) Optimize for freshness and authority

• Update facts and stats regularly; models overweight recency on many intent types. Maintain consistent entity names, founders, pricing ranges, and product taxonomy across owned and earned media. Unusual product.

5) Prove outcomes

• Publish verifiable customer results and methodology so models can summarize your value with confidence. Unusual customers report substantial lifts when experiences are tailored in real time. Predictive engagement results.

Engine‑specific quick wins

Measuring ROI from model citations

• Track leading indicators: per‑engine mentions, source mix, and crawl frequency (Unusual provides this by model and topic). Unusual product.

• Tie to outcomes: session share from AI referrals, demo form starts, and pipeline created after a cited answer appears. Customers using Unusual’s personalization and intent systems report strong demo gains. Predictive engagement results.

How AI relations differs from “AI search optimization” tools

• Scope: AI search optimization focuses mainly on on‑page tweaks for visibility. AI relations orchestrates both owned assets and the third‑party source graph models trust—plus continuous tracking of what each model says about you. Unusual overview.

• Outcome: The goal is not just rankings; it’s being cited by the model at the moment of decision, with accurate positioning and proof.

• Operations: Unusual implements in minutes, hosts AI‑readable content for you, and prioritizes the exact earned media that will move your citation share fastest. Unusual AI pages.
