Definition
YouTube SEO is the practice of optimizing video titles, descriptions, transcripts, and metadata so videos surface both in YouTube’s own search and in the wider answer engines that draw on video. It treats a video as indexable content, the text and structure wrapped around footage, rather than as a file that speaks for itself.Why It Matters for AI Search
Answer engines increasingly pull from video, reading transcripts and descriptions to lift a spoken explanation into a written answer. A video with a clean transcript, a plain title, and a described structure gives a model text it can retrieve; one that leans on the footage alone gives it nothing to read. YouTube is also a search engine in its own right, one of the most used, so the work serves two retrieval systems at once. Making a video legible as text is what lets it be found by systems that cannot watch.Related Terms
