The jury’s out on how useful Google My Business posts are, but they have promise. I like ‘em so far. They’re quick and easy to create, and they show up in one of the very few areas of the brand-name search results that you can control.
The annoying thing is you have to keep adding posts. They expire every 7 days. What if you like the post you put up last week, and want to keep it around for longer? Nope.
You could always re-post the same thing, but you’d lose the all-too-basic stats Google shows you on each post. Also, an endless string of the same post would look odd to anyone who pulls up your older posts.
