The Social Planner supports a variety of post formats across all connected platforms. Choosing the right format for each piece of content improves reach and engagement, since social media algorithms prioritize native formats — a Reel performs differently from a feed post even when the video content is identical. Navigate to Marketing > Social Planner > New Post and select your platforms. The composer adapts based on the platforms you choose, showing the format options available for each.

​
Standard feed posts

A standard feed post is a single piece of content — text, one or more images, or a video — that appears in the main feed of followers on that platform. This is the baseline post type available on every supported platform. Supported on: Facebook, Instagram, LinkedIn, Pinterest, Google My Business, X (Twitter), Threads, Bluesky What you can include:
  • Text caption (length limits vary by platform)
  • Up to 10 images in a single post
  • One video per post (format and duration limits vary by platform — see the specs table below)
  • A link preview (OG meta URL)
  • Hashtags and mentions
When you attach multiple images to a standard post on Instagram, it becomes a carousel automatically. On Facebook, multiple images are posted as a gallery.

​

Frequently asked questions

Yes. Select multiple accounts in the account selector when creating a post. The content and media are sent to all selected platforms simultaneously. Use the per-platform preview panel to check how the post will look on each platform before publishing, and make any platform-specific adjustments.
A standard video post appears in the main feed and is shown primarily to existing followers. A Reel is distributed more broadly — it can appear in the Reels tab and be shown to users who do not yet follow your account, making it more effective for reaching new audiences. Reels must be vertical (9:16) and have platform-imposed duration limits.
Yes. Select both Facebook and Instagram in the account selector and choose the Reel post type. The same vertical video will be scheduled as a Reel on both platforms. Check the preview panel for each platform to confirm the content looks correct before scheduling.
Stories may require confirmation via the HoopAI mobile app depending on your account type and the platform’s API restrictions. Ensure the mobile app is installed, push notifications are enabled, and your Instagram account is a Business or Creator account connected via the Facebook API.
