Yes, for two different reasons that work together: consistent activity sends a trust signal to Google, and gives potential customers an extra reason to engage with your profile specifically instead of a dormant competitor's.
The Posts Feature Is Often Underused
Your Google Business Profile includes a "Posts" feature that lets you share updates, offers, events, or short news — very similar to social media posts, yet most businesses never use it despite it being free and straightforward.
How Google Reads Ongoing Activity
A profile that's posted to regularly looks like an actively managed, living business to Google, unlike one that's been static since verification. This activity feeds into the set of signals Google uses to assess a business's reliability and continuity, alongside reviews and photos.
Offer Posts Specifically Carry Extra Weight
Offer posts sometimes appear in a distinct format that catches a searcher's attention more than a generic post. If you have a limited-time deal or a seasonal discount, this feature specifically is a direct opportunity to drive extra clicks.
No Need for a Complicated Schedule
You don't need to post daily. One post a week — a simple update, a fresh photo with a caption, or a short offer — is enough to keep the profile looking active to both Google and visitors.
Conclusion
The Posts feature is free, simple, and overlooked by most competitors — which is exactly what makes it an easy, low-cost opportunity to set your profile apart.
