The United States row is measured the same way as the others. The US study page it links to uses an earlier, narrower pull, so its figures differ.

How was this measured?

  • ·Data: Ahrefs Brand Radar, AI responses, Germany, data date 14 November 2026: every answer whose prompt Ahrefs files under Jobs and Education > Education (including its subcategories), with no site filter. 109,804 rows exported in slices under Ahrefs' row cap, each checked against the count Ahrefs showed.
  • ·Answers: 109,804 unique answers after removing duplicates (same platform, prompt, opening text and date), dated 17 August 2026 to 14 November 2026.
  • ·Platforms: Google AI Overviews, Google AI Mode, ChatGPT, Perplexity, Microsoft Copilot, Google Gemini. Grok was paused in Ahrefs during this period.
  • ·Measure: the share of answers that cite a source, or a source type, at least once.
  • ·Source types: each cited page is assigned one type by fixed rules (domain lists and suffixes such as .gov or .ac.jp), the same rules in every country.
  • ·Anonymized sites: the 33 international education sites of the US study are shown as Brand 1 to Brand 33, numbered by how many answers cite them across all countries.
  • ·Platform mix: Google AI Overviews are 62.2% of the answers here, so all-platform figures lean toward Google.
  • ·One snapshot: this is one pull, not a trend.
