Video for AEO: Google Cites YouTube. ChatGPT Almost Never Does.

What we tested

On 17 October 2026 we ran 60 questions an Australian business owner or customer might ask. Ten each of how-to, definitions, B2B service questions, product comparisons, local services and health or money questions. Each one went through Google from an Australian location on desktop and mobile, then through ChatGPT, Perplexity, Gemini and Claude with web search switched on and an Australian location or context.

Then we counted every source each answer linked to, and how many of them were videos.

Content Department test, 60 queries, 17 October 2026. Google results via DataForSEO’s SERP API set to Australia; the other engines via their APIs with web search on.

API answers can differ from what you see in the ChatGPT or Gemini apps, so treat the non-Google rows as directional. They line up with the large US studies below. Method and raw results are kept on file.

Video for AEO is a Google play

Every big citation study says the same thing, and our Australian numbers match. Ahrefs’ September 2026 data puts YouTube as the most-cited domain in AI Overviews, tied for first in AI Mode, and only eighth in ChatGPT.

Ahrefs measures share among the top 50 cited domains, so its percentages run higher than a share of every citation. Scrunch reports Perplexity almost stopped citing YouTube around 12 August 2026. Our test agrees with Scrunch: 3%.

That would be a footnote if Australians mostly used Google’s AI. They don’t. Roy Morgan found 45% of Australians aged 14 and over used ChatGPT in an average four weeks in early 2026, against 21% for Gemini. The engine most people mean when they say “AI” is the one that barely cites video.

So anyone selling you “video that gets you into ChatGPT” should be able to show you a ChatGPT answer that cites a video. In our test there were none.

Google cites the moment, not the video

The single most useful finding is how Google links to video. More than half of its YouTube citations were timestamped links like youtube.com/watch?v=…&t=141. Google had picked one sentence out of a video and sent the reader straight to second 141.

BrightEdge found the same pattern in the US: 50% of AI Overviews’ YouTube citations are timestamped, against 0.6% for ChatGPT. OtterlyAI, looking at more than 100 million citations, found timestamped links only on Google’s surfaces, and that 78% of timestamped videos were cited more than once, often across two to five chapters.

The Brandtech Group, Jellyfish’s parent, published Australian figures in August 2026 from its weekly run of a quarter of a million pre-purchase questions across six AI model families. Across all engines, one in seven YouTube citations pointed to an exact timestamp. The mix of long videos and Shorts changed a lot by category:

Source: The Brandtech Group / Jellyfish, YouTube’s new role in building brands for both audiences, August 2026. Consumer categories only, and the paper is also a pitch for Brandtech’s own tracking and creator ad services.

Where people are comparing options, long videos with clear chapters win. Where they want a quick demonstration, Shorts get a real share.

That tells you how Google reads video. It isn’t judging your lighting or your edit. It is reading the transcript, the chapters and the description, finding the line that answers the question, and pointing at it. Gemini’s developer API can watch YouTube directly at one frame a second, but in search it is the words that get quoted.

Which means the transcript is the product. The video is how you make it.

The standard advice, tested

Most AEO video explainers repeat the same five rules. Here is each one next to what the data shows.

The rules that hold up are the boring ones. Say the answer plainly in a full sentence. Name the things you are talking about. Break the video into chapters. None of that is new. It is how good explainer video has always been made.

Video wins some questions and loses others completely

YouTube’s share swung wildly depending on the kind of question.

Desktop and mobile combined: 120 results, 105 with an AI Overview.

Show-me questions belong to video. If a person needs to see a hand doing something, Google sends them to a video. Every how-to AI Overview in our test cited YouTube.

Buying questions belong to pages. For “how much does a corporate video cost in Australia” and “video production cost Sydney”, Google mostly cited Australian production companies’ own pricing articles. Text, with numbers in it. The best-placed video businesses won those answers with a written page, not a showreel.

Local questions skip AI entirely. Only 5 of 20 local searches produced an AI Overview, and none cited a video. If you are a plumber or an electrician, AEO video will not win you jobs in your suburb. Your Google Business Profile and reviews still do that.

Being cited is not the same as being visited

Here is the part the AEO pitch tends to leave out. Pew Research tracked 900 US adults’ real browsing: when an AI summary appeared, people clicked a link inside it on 1% of visits. Ahrefs measured a 58% drop in clicks to the number-one result when an AI Overview sits above it. Across 81,947 sites, Ahrefs found AI assistants sent about 0.25% of total traffic, and Google sent 210 times more.

And the conversion story is shakier than it sounds. The most careful study we found, Amsive’s analysis of 54 sites, found AI referral traffic converted at 4.87% against 4.60% for organic search, a difference too small to count.

So why bother? Because the value is in being named, not in being clicked. Seer Interactive found brands cited inside an AI Overview earned 35% more organic clicks than those left out. And in Ahrefs’ study of 75,000 brands, the factor most closely linked to AI visibility was how often the brand was mentioned in YouTube videos (a correlation of 0.737), well ahead of Domain Rating (around 0.3). Correlation, not proof, but a strong one.

That second number is the strategy hiding in plain sight. Your own videos help. Being talked about in other people’s videos may help more.

It does not stay won

Scrunch found a YouTube video’s citation rate fell about 43% within a month of first being cited. BrightEdge watched YouTube’s share of ecommerce AI Overview citations jump from 31% to 65% in 11 weeks in mid-2026, because Google changed its weighting, not because anyone made better videos. Perplexity appears to have dropped YouTube almost overnight in August.

A single “AEO video” is a lottery ticket. A library of answers that keeps growing is a position.

What we would actually do

1. Put it on YouTube, long-form. That is where the citations go. Two to ten minutes, one topic, properly titled. Cut Shorts from it for social, but don’t expect them to do the AEO work.
2. Chapter every video like a contents page. Each chapter title is a question a buyer asks. The first sentence after it is the answer, said in full: “A two-minute brand video in Sydney usually costs between…”, not “so, yeah, it depends.”
3. Fix the transcript. Upload your own captions instead of trusting auto-captions. Make sure your brand, product names and suburbs are spelled right, because that text is what gets read.
4. Turn every video into a page for ChatGPT. ChatGPT and Claude cite text. Publish the answer as an article on your own site with the video embedded, so the same expertise is there in a format each engine reads.
5. Get into other people’s videos. Podcasts, industry channels, supplier tutorials, reviews. Being named in someone else’s transcript is the strongest signal in the Ahrefs data.
6. Don’t make video for pricing or local questions. Write the page with real numbers instead. That is what wins those answers.
7. Measure citations, not views. Pick 20 questions your buyers ask and run them through Google and ChatGPT every month. Count whether you appear. That is the only scoreboard that matters here.

Our own score: zero

We ran our own name through the same test. Across 60 questions, five engines and 360 answers, contentdept.com.au was not cited once. Several of the questions are ones we answer for clients every week, and AI Overviews cited other Sydney studios’ pricing pages for them.

So we are doing what this page recommends: chaptered long-form answers on YouTube, a written version of each on this site, and a monthly citation check. We will publish how it goes, including if it doesn’t work.

If you want the same for your business, that is the work a content department does. We find the questions your buyers ask, film the answers in batches with your people at your office or in our Sydney studio, and publish each one as a chaptered video and a page, so it is ready for whichever engine your customers use.
