The 50 Most-Cited Websites in Gemini (September 2026)

Google has folded Gemini into Search, Android, Chrome, and Workspace, and the audience has grown fast: on Alphabet’s Q4 2025 earnings call, Sundar Pichai said the Gemini app had passed 750 million monthly active users, up from 650 million a quarter earlier. At that scale, the sources Gemini cites help shape what hundreds of millions of people read every month.

To see which sites those are, we tracked every domain Gemini cited across a broad set of US queries, then ranked them by mention share — each domain’s slice of all the citations the top sources collectively earn. The leader is www.reddit.com, capturing 28.5% of citations.

The numbers come from Ahrefs’ Brand Radar, which tracks the responses AI platforms give to a large, search-backed set of real user queries. For this article, we looked at every domain Gemini cited across over 3 million US queries spanning all topics, then counted how often each domain appeared as a source.

For each website we report:

Mention share — a domain’s citations as a percentage of the summed citations of the top 50 most-cited sources. It shows how much of Gemini’s “source attention” each website captures.
vs last month — how the domain’s rank has moved since the previous monthly snapshot (▲ climbed, ▼ fell, or NEW if it wasn’t in last month’s top 50).
Pages cited — the number of distinct pages on the domain that Gemini cited, a measure of how broadly the site is referenced rather than how often.
DR (Domain Rating) — Ahrefs’ 0–100 measure of a website’s backlink-profile strength, included for context on each source’s overall authority.

This article is generated and automatically kept up to date every month by Agent A, our AI agent. Each month it pulls the latest Brand Radar data, recalculates mention share and rank movement, and refreshes the chart and table above — so the figures always reflect the most recent snapshot.

To track your brand’s presence in Gemini, you’ll need to use Ahrefs’ Brand Radar.

Measure your brand’s visibility in Gemini, see the specific queries where your brand gets mentioned (and the ones where it doesn’t), the pages that mention your brand, and then compare every metric with your closest competitors:
