Your property page is indexed, but Airbnb and VRBO listings still rank above it in searches for the house name.
Why this happens. Airbnb and VRBO listings have more history with Google, so outranking them takes time.
Keep the house name in the listing titles on every channel you use. Create or update your Google Business Profile to point Google at your site as the official page for that property. Consistent use of the name across channels helps Google associate your site with it over time.
