These are the domains appear most in Google’s AI Overviews

Ahrefs analyzed millions of AI Overview responses to identify the websites Google cites most often. The results show that a small group of high‑authority, user‑generated and video platforms dominate citations.

Top domains cited in AI Overviews

According to Ahrefs’ July 2026 data, the most‑cited domains in Google AI Overviews are:

1. YouTube – 20.9% mention share
2. Reddit – 19.6%
3. Facebook – 11.6%
4. Google.com – 6.0%
5. Instagram – 5.2%
6. Wikipedia – 4.8%
7. Amazon – 4.0%
8. Quora – 4.0%
9. TikTok – 3.6%

These nine sites account for the majority of all citations, with YouTube and Reddit alone making up around 40% of mentions.

What this means for SEO and content strategy

AI Overviews rely heavily on:

• Video content (YouTube)
• Community discussions and real‑world experiences (Reddit, Quora, Facebook)
• Official product and help pages (Google, Amazon)
• Visual social content (Instagram, TikTok)
• Encyclopedic reference material (Wikipedia)

For brands and publishers, this suggests that earning citations in AI Overviews is less about chasing traditional “top 10” rankings and more about creating content that AI systems see as authoritative, experiential, or definitive.

How to improve your chances of being cited

To increase visibility in AI Overviews:

• Publish clear, well‑structured answers to common questions in your niche.
• Leverage video, especially on YouTube, with descriptive titles and transcripts.
• Encourage genuine discussions and reviews on trusted platforms like Reddit and industry forums.
• Maintain strong technical SEO and site authority so AI systems can trust your content.
• Optimize for entity‑level clarity (about your brand, products, and topics) so AI can reliably reference you.

As AI Overviews become more prominent, appearing as a cited source may matter as much as, or more than, ranking in the traditional organic list.
