Anybody still bothering with GBP posts?

Honest question. I have around 8 local clients, mostly dental. On some profiles i was doing the 2-3 posts per week thing, on others i ignored it completly, and i cant see difference in map pack or in insights.

Reviews move something for sure. Filling all the service and attribute fields move something. Photos maybe little bit for 2 weeks. Posts i see nothing at all.

Anybody actually seeing result from them or we all just doing it because google say so?

Results differ one niche to another

Mostly GBP posts to keep the listing active and freely use the targeted keywords.

I have seen that too. The posts on GBP seem to be more helpful in driving engagement, branded search and making sure that the profile remains active as opposed to having an impact on Map Pack rankings directly
