In episode 250 of the weekly Hump Day Hangouts by Semantic Mastery, one viewer asked if video embeds on GMB posts are useful when ranking GMB listings.
The exact question was:
By the way, you mentioned previously that we can create a GMB post with a video embedded in it and use the url for that post to run a MGYB Embed job, but will that provide any significant ranking power to the GMB listing or just for the post itself? . . . Thanks again
