Before You Start
Google Business Profile is not social media -- it's local SEO. Posts appear on Google Search, Google Maps, and Google Knowledge Panel. They contribute to local search ranking. Posts are visible for about 7 days before being archived. Post weekly minimum.
- Requires a verified Google Business Profile
- Posts appear in Google Search + Maps (not a social feed)
- Videos are not supported
- No text-only posts via API (media or CTA recommended for visibility)
