Who Google cites in the AI Overview — and whether you even have one

Spoiler: not every query has an AI Overview, and when one appears, Google tends to cite Reddit and YouTube before any brand.

I found out the dull way: I typed “what is generative engine optimization” into our free Google AI Overview checker and got nothing. Google’s AI Overview lifts the answer straight into the SERP and cites a handful of sources — but it doesn’t appear everywhere, and it usually cites something other than brands. So why guess?

What the checker shows

Paste a query (and optionally a domain) and the checker reads the live SERP to answer three things: whether this query triggers an AI Overview, which exact domains and pages Google cites inside it, and whether your own domain made it in. Below that, the organic top-10 for context. One request, and the result is a snapshot of the real SERP — not a guess.

Lesson 1: AI Overviews aren’t everywhere

The first thing live runs reveal is that AI Overview presence is unpredictable across queries. “What is generative engine optimization” had no AI Overview at check time, while “best project management software” and “how to improve core web vitals” did. Why would a definitional query get nothing and a commercial one a full box? No clean theory here (probably consensus), and the takeaway doesn’t need one: before optimizing for the AI Overview, confirm it exists for the queries in question — otherwise the fight is for a surface that isn’t there!

Lesson 2: it cites Reddit and YouTube, not you

When an AI Overview is present, the citation mix is sobering. For “best project management software” Google cited reddit.com, icagile.com, wrike.com and youtube.com; for “how to improve core web vitals” — web.dev, developers.google.com, youtube.com and ahrefs.com. Brands sit next to forums, videos and references — notice who is absent? Most likely, the reader. That list is the target map: to enter the answer, a site either becomes one of those sources or earns a mention inside them.

What to do with the result

The list of cited domains is a ready-made digital-PR plan: be present where Google takes its answer. If you’re absent from an AI Overview a competitor is in, the exact target is now visible — no more meeting arguments! The full picture across the whole query set — Perplexity, ChatGPT, Claude, Gemini and Google AIO at once, with share of voice — comes from the paid AI-Visibility Report.

One query first, though — seems only fair to check the room exists before redecorating.
