How do video captions improve real estate listing SEO on YouTube?

YouTube indexes caption text as searchable page content, making captioned listing videos discoverable for terms like the property address, neighborhood name, specific feature keywords ('4 bedroom home Dallas'), and price-range terms. Agents who caption tours with accurate property details capture organic YouTube search traffic from buyers researching specific neighborhoods and price points. Caption files (SRT format) uploaded manually perform even better than auto-generated captions for SEO indexing accuracy.
