Google explained the indexing of 360 images
Google employer John Mueller explain how 360 images indexing.
One user asked on Twitter whether are processing these images differently than usual, and whether to optimize file names.
Muller was asked to give a specific example:
Do you have an example I can check? If they're normal image files, we can treat them as such.
The webmaster gave the following link. Mueller said that in this case we are talking about switching between images, so that Google can index one of these frames.
It looks like it's switching out the images, so we'd probably just index one of those image frames (as a normal img)
If the 360-degree image consists of several pictures, then Google can index and rank. And that's exactly what the search engine will choose and how will be made this choice is unknown.
The Google Images does not allow to find images in the 360 format.
