Optimization for "Search by Photos" feature

[DmitriiK]

Howdy, fellow mozzers,

Does anyone know what affects a given company photos show up in the "Search by Photos" section?

I can't find any decent info..

Here is the link to SEL, describing the feature (not even google themselves seem to have an announcement about it). https://searchengineland.com/google-showing-mobile-search-by-photos-option-in-selected-local-verticals-323237

Thanks in advance!
