In episode 329 of Semantic Mastery's weekly Hump Day Hangouts, one viewer asked if daily posting on GMB help in ranking the listings higher.
The exact question was:
(2) I am presuming that daily GMB posts are allowed, and I recently read that posting daily on GMB will significantly help the listing to rank higher, and that optimizing the post for your targeted search terms will also significantly help with ranking, are either or both of those true, and if so, how much of an impact will either have? . . . Thank you VERY much for your help as usual, it is greatly appreciated
