Any reason not to group GMB locations?

[danieldaher]

I have 17 locations in Google My Business all for one company. Is there any reason NOT to group them and transfer ownership to a new grouped location? It won't have any negative SEO effect, right? Just making sure I won't lose reviews or age of accounts.

While ownership of your listings is unlikely to impact SEO, be aware that Google is being extremely hyperactive about putting listings in a pending state right now following many kinds of changes. So, just know, if you make a change right now, it could have this effect.
