GeoBooster posts are called Moments. You can create them two ways: from the web app or from the mobile app.
From the web app
Open the new Moment page, choose the business, employee and category, write the content, add photos, and pick where it should go. A Moment can publish to any combination of the location's Google Business Profile, Facebook, Instagram, and a webhook (which feeds your own service and any Zapier or Pabbly automation). Facebook and Instagram post natively once those accounts are connected to the business.
From the mobile app
The mobile app is the most common way staff post, capturing photos and content on site. If the user does not have moderation turned on, the Moment is usually live on Google and the website within a few minutes.
If a user has pre-moderation on, their Moments wait for approval in the LocalOptics dashboard before publishing. See GeoBooster Settings.
