In episode 222 of Semantic Mastery's weekly Hump Day Hangouts, one viewer asked if long-form GMB posts perform better in terms of keyword ranking.
The exact question was:
I noticed that for GMB post, there is room for 1,500 characters to write a post, and yet in the local lease Pro training you use only a handful of characters to complete a post.
Shouldn't we try to write a longer post to covert more keywords in our copy so we can rank for those keywords too? Or is there a point of diminish return when we write a longer piece of text that yield no additional benefits?
