The Most Cited Domains on Google AI Mode in March 2026

Based on Promptwatch data from Feb 28 - Mar 30, 2026. Citations tracked from real prompt responses using Google AI Mode.

What this means for you

March belongs to YouTube: at 3.30% of Google AI Mode citations it takes double Reddit's share (1.65%) and almost four times LinkedIn's (0.89%). Six of the top seven domains are video, social, or community platforms. AI Mode leans on user-generated and visual content far more than on traditional publishers; Forbes manages only 0.17%.

At the same time, the tracked majors together account for well under 10% of all citations. AI Mode's query fan-out spreads the rest across thousands of smaller domains, keeping the door open for niche sites in a way that classic ten-blue-links rankings never did.

How to act on it

• Make video part of your GEO playbook. YouTube's 3.30% is double Reddit and nearly four times LinkedIn. Tutorials, product demos, and comparison videos on YouTube are earning citations that blog posts alone won't.
• Maintain an authentic community footprint: Reddit (1.65%) and the social trio of LinkedIn, Facebook, and Instagram all outrank every publisher in this chart, so genuine participation in the threads where your category is discussed pays off.
• Exploit the publisher gap: with Forbes at just 0.17%, big-brand media isn't crowding out AI Mode citations the way it dominates classic SERPs. Specific, well-organized answer pages on your own domain compete on merit here.

Google AI Mode Citation Share February vs March 2026

Side-by-side comparison of citation share for the top domains on Google AI Mode between February and March 2026.

What this means for you

The headline move from February to March is YouTube's surge from 1.88% to 3.30%, a 76% jump in a single month, while TikTok tripled from 0.05% to 0.16%: a clear tilt toward video and short-form sources. On the losing side, Yelp fell from 0.37% to 0.15% and Google's own domain slipped from 0.79% to 0.58%. Reddit (+17%) and Instagram (+31%) also gained ground. Month-to-month swings of this size show how quickly AI Mode's retrieval preferences shift.

How to act on it

• Re-check your citation share every month instead of quarterly. When the #1 source can grow 76% in four weeks, a stale snapshot will send your content investment to the wrong channels.
• Ride the video wave while it lasts: converting your best-performing written guides into YouTube (and even short-form) versions targets exactly where AI Mode's citations are flowing this month.
• Don't hang your local or review strategy on a single platform. Yelp's share more than halved in one month. Spread structured review and reputation signals across Google Business Profile, industry directories, and your own testimonial pages.
