Video SEO is the work of making videos easy to find, understand and use, in Google's results, on YouTube, and now in the answers AI assistants write. The first two are well-known disciplines with documented rules. The third is new, and it is changing why video SEO matters: YouTube has become one of the sources AI answers lean on most.
For the definition alone, see the video SEO entry in our glossary. This post is the practical part: what Google asks for, what to do on YouTube, and how video shows up in AI answers, including in the answers to our own tracked questions.
What does Google need to find and show your videos?
Google's video best practices are specific. The essentials:
A watch page for each video
Google recommends a dedicated watch page for each video where it makes sense for your business: a page whose main purpose is showing that one video. The video must be embedded on the page and not hidden behind other elements. A video buried halfway down a long article can still be found, but a watch page is what Google's video results are built around.
VideoObject structured data
Describe each video with VideoObject structured data, and give each one unique values for its thumbnail URL, name and description. Copying the same description onto every video makes them indistinguishable.
A video sitemap
List your videos in a video sitemap, or add video entries to your existing sitemap, with the metadata Google needs, including where the player and the video file live. It helps Google discover videos it would otherwise miss.
A stable, usable thumbnail
Thumbnails must be at least 60x30 pixels, larger is better, in a supported format such as JPEG, PNG or WebP, and available at a stable URL. A thumbnail URL that changes every week breaks the result.
Key moments
Let searchers jump to the part they need. Mark segments with Clip structured data for exact timestamps, or with SeekToAction so Google can detect them automatically.
Check the video indexing report
Search Console's video indexing report shows which watch pages Google indexed with a video and why others were not. Check it after you publish and after any template change.
What should you do on YouTube?
YouTube is a search engine with its own results, and a source other engines cite. The same habits that make a web page easy to quote make a video easy to find there.
- Title the video as the question it answers. "How to set up X in five minutes" beats a clever name. Put the specific thing first.
- Answer in the first seconds. Viewers and summaries both reach the opening first. Say what the video shows before the intro.
- Write a real description. The first two lines carry the answer in words. Below, add context, links to the related page on your site, and the chapters.
- Add chapters. Timestamped chapters in the description give the video key moments in Google and make it easier for an engine to point at the relevant part.
- Use accurate captions. Auto-captions miss product names and jargon. Corrected captions are text that machines can read.
- One question per video. A forty-minute webinar answers twenty questions badly. Cut it into short videos, each answering one.
How does video show up in AI answers?
This is the part that has changed fastest. Ahrefs' study of 863,000 search results pages, published in March 2026, found YouTube was the most cited domain in Google's AI Overviews, with 5.6% of all citations, and had grown 34% in six months. Among the AI Overview citations that came from pages outside Google's top 100 organic results, 18.2% were YouTube URLs. In other words, a video can be cited for a question where it ranks nowhere in the ordinary results.
We see the same in our own data. Our product reads the answers to 61 questions about our category on ChatGPT and Perplexity every day. Between 4 September and 4 October 2026, youtube.com received 245 of the 100,380 citations in those answers. That is a small share overall, because our questions are mostly about software where review sites and docs dominate. But it concentrates on the how-to questions: in Perplexity's 54 answers to "why am I not showing up in ChatGPT" between 5 September and 4 October 2026, youtube.com was the most cited domain, with 96 of the 535 citations, ahead of OpenAI's own help centre (66), as the chart at the top of this page shows. For a practical "how do I fix this" question, the engine reached for videos.
The lesson: video earns citations on questions where showing beats telling. Troubleshooting, setup, "how do I", product walkthroughs. A clear, short video that answers one of those questions, with a title, description and chapters that say what it covers, is a source an engine can quote.
