That is a really smart observation, Rebeca! You are right that Google is a huge funnel, but for STRs it works a bit differently than a standard local business profile.
Google has a dedicated product called Google Vacation Rentals. It puts your listing right on Maps, but unlike a standard business profile, you usually can't create it manually due to residential address rules.
The trick to getting visibility there is using a software partner (like Hostaway, Guesty, or Smoobu).
They have a direct integration that pushes your listing to Google Maps automatically.
It is a massive win for direct bookings because it sends the guest straight to your own website, bypassing the Airbnb fees completely.
Do you currently have a direct booking site set up for the properties you consult for?
