What this report covers

This report is built on the LLM Pulse dataset — the largest ongoing scrape of AI search answers anywhere. It ranks the websites that AI search engines cite most when they answer real user questions, across every answer we captured on ChatGPT, Perplexity, Gemini, Google AI Mode and Google AI Overviews in the last 28 days.

If you run SEO, PR or content for a brand, this list is your first look at the sources AI trusts today. If your domain is here, you are already part of the answer layer. If it is not, these are the competitors you need to catch — and LLM Pulse is the fastest way to track every citation, mention and sentiment for your own brand side-by-side with them.

How we measure this

  • LLM Pulse runs thousands of real prompts every week against ChatGPT, Perplexity, Gemini, Google AI Mode and Google AI Overviews and captures the full response — the same pipeline enterprise customers use to monitor their own brands.

  • For each answer we parse every citation and resolve it to its registrable domain (so www.wikipedia.org and en.wikipedia.org roll up to wikipedia.org). Inside the LLM Pulse app, the same data is broken down per prompt, per country and per competitor.

  • A domain counts once per answer, even if cited multiple times. An answer with zero citations is excluded from the denominator.

  • The rolling window is the last 28 days ending on the snapshot date shown above. The ranking is rebuilt daily from the live LLM Pulse dataset.

Why this matters

AI search is becoming the front door for a large share of high-intent queries. Being cited means your content is part of the answer AI gives millions of users — even when they never click through. Most analytics tools cannot see any of it.

That is exactly the gap LLM Pulse was built to close: track your own citations, mentions, sentiment and share of voice across every AI search engine, benchmark against competitors, and catch every change in the AI answer layer before it costs you traffic.

If your competitors are on this ranking and you are not, they are capturing mindshare you cannot measure with traditional SEO tools. Run a free AI Visibility Report on your domain — or start a free 14-day trial of the full LLM Pulse platform.
