Page Formats and Content Types AI Engines Cite

Domain Types and Marketer Influenceability

A large share of what AI engines cite sits outside any marketer's reach, concentrated on Wikipedia, homepages, and a handful of high-authority domains.

  1. 06

    Only 32.3 percent of ChatGPT's top 1,000 citations are influenceable content such as reviews, news, and blog posts, leaving roughly 67 percent off-limits to marketers.

  2. 07

    28.3 percent of ChatGPT's most-cited pages have zero Google organic keywords and no traditional search visibility.

    65.3 percent of ChatGPT's cited pages that do rank belong to sites with a Domain Rating of 81 or higher, with a median DR of 90.

  4. 09

    847,338 citations made Reddit the most-cited domain in ChatGPT's US responses, nearly double Wikipedia's 431,710, across 9.6 million analyzed queries.

  5. 10

    4.39 million citations went to Reddit and 2.72 million to English Wikipedia in ChatGPT's global responses, the two most-cited domains worldwide.

Retrieved vs Cited

Being retrieved by an AI engine and being cited in its answer are two different hurdles, and most retrieved content from social sources never makes the answer.

  1. 11

    49.98 percent of the URLs ChatGPT retrieves end up cited in its answers, based on an Ahrefs study of 1.4 million prompts.

    Source: Ahrefs, 2026

  2. 12

    88.46 percent of URLs ChatGPT retrieves through search get cited, compared with 12.01 percent of news URLs, 1.93 percent of Reddit URLs, and 0.51 percent of YouTube URLs.

    Source: Ahrefs, 2026

  3. 13

    67.8 percent of ChatGPT's retrieved-but-never-cited URLs come from Reddit, showing heavy retrieval does not translate into citations.

    Source: Ahrefs, 2026

  4. 14

    0.602 is the average semantic similarity between a prompt and the titles of pages ChatGPT cites, versus 0.484 for retrieved pages it skips, making title relevance a citation factor.

Citation Overlap Across Platforms

Each AI platform builds answers from a largely different source pool, and overlap with Google rankings or with other AI engines is consistently low.

  1. 15

    Only 12 percent of links cited by ChatGPT, Gemini, and Copilot appear in Google's top 10 results for the same prompt, across 15,000 long-tail queries.

    Source: Ahrefs, 2025

  2. 16

    28.6 percent of Perplexity's citations rank in Google's top 10, the highest Google overlap of any AI assistant Ahrefs tested.

    Source: Ahrefs, 2025

  3. 17

    Roughly 80 percent of AI assistant citations do not rank anywhere in Google for the original query.

    Source: Ahrefs, 2025

  4. 18

    Only 13.7 percent of citations overlap between Google's AI Overviews and AI Mode, even though the two systems reach the same conclusions 86 percent of the time, across 730,000 response pairs.

  5. 19

    Only 11 percent of cited domains appeared across multiple AI platforms in an analysis of 118,000 AI answers spanning ChatGPT, Perplexity, Google AI Mode, and Claude.

    21.87 citations per response is Perplexity's average, versus 8.34 for Google AI Mode, 7.92 for ChatGPT, and 5.67 for Claude.

  7. 21

    38 percent of AI Overview citations now pull from Google's top 10 ranking pages, down from 76 percent measured a year earlier.

Citation Churn and Correlation Factors

AI citations turn over constantly even when the answer's meaning stays put, and the factors that predict citation look nothing like traditional link-based SEO signals.

  1. 22

    2.15 days is the average persistence of an AI Overview before its content changes, with a 70 percent chance of changing between observations while semantic similarity holds at 0.95.

    Source: Ahrefs, 2025

  2. 23

    54.5 percent of URLs overlap on average between consecutive AI Overview responses for the same query, meaning nearly half the cited sources are new each time.

    Source: Ahrefs, 2025

  3. 24

    0.737 is the correlation between YouTube mentions and AI brand visibility across ChatGPT, AI Mode, and AI Overviews, the strongest factor in Ahrefs' study of 75,000 brands.

    Source: Ahrefs, 2025

  4. 25

    0.664 to 0.709 is the correlation range for branded web mentions with AI visibility, while Domain Rating correlates at only 0.266 to 0.326 and site page count at 0.194.

    Source: Ahrefs, 2025

  5. 26

    0.779 is the output overlap correlation among ChatGPT, AI Mode, and AI Overviews, meaning the three assistants largely mention the same brands even while citing different pages.

    Source: Ahrefs, 2025

  6. 27

    99.9 percent of AI Overviews appear on informational intent keywords, and AIOs trigger on 21 percent of all keywords, based on an analysis of 146 million SERPs.
