Use the Embed Button from Google My Business
Google Virtual Tours provides the ability to embed your published tour onto virtually any website or social media you would like. From your virtual tour, will need to click on the Menu on the top left of the tour:
Option 1: Link: By clicking on the Link tab you’ll be able to display the URL in which you can email or post on any marketing material. Feel free to use the URL shortener (check the box).
Option 2: Embed Image: By click on the Embed image tab, you’ll be able to copy and paste the tour onto your website. You will be able to select “Large”, “Medium” or “Small” as three standard defaults. This iFrame code can be pasted and coded onto your website.
