Search & watch
The logged-out discovery loop, page by page: a search-results grid that behaves like its own search engine, a watch page engineered to keep the next video one glance away, and the sign-in wall that finally appears when an anonymous viewer reaches for a feature that needs an identity. The flow shows how YouTube sequences free consumption first and the account ask last.
Search results — a results page that is its own search engine
YouTube treats search as a destination, not a detour: results come back as a dense vertical list of thumbnail-forward cards — title, channel, view count, age, and a hover-preview — with filter chips across the top and the occasional 'people also watched' shelf spliced in. The ranking is doing recommendation work even here, mixing the literal query match with channels and playlists it thinks will hold you. For a logged-out visitor there's no personalization to lean on, so the page sells on social proof — view counts and recognizable channels carry the click.
