How to Customize Social Planner Posts Per Channel in Sparkforge

By Sparkforge Support Team ·Last reviewed May 3, 2026

The Customize for Each Post toggle in Sparkforge Social Planner lets you write different copy for Facebook, Instagram, LinkedIn, and GMB in one composer — respecting each platform's character limit and media format.

Sparkforge Social Planner has a per-channel customization toggle. Pick multiple platforms in one post, flip the toggle, and write distinct copy for each — Facebook, Instagram, LinkedIn, and Google Business Profile (GBP) — without creating separate posts for every channel.

What you can do

  • Multiple platforms in one composer — Facebook, Instagram, LinkedIn, GBP.
  • Per-channel content with character limits respected on each.
  • Toggle between unified copy (same for every channel) and customized copy (different per channel).
  • Content AI integration to generate copy up to ~900 words and adapt size per platform.
  • Schedule immediately or queue for later.

How to use it

  1. Go to Marketing → Social Planner in the sidebar.
  2. Click Create New Post.
  3. Select multiple social channels (Facebook, Instagram, LinkedIn, GBP, etc.). The Customize toggle only appears once you have at least two channels selected.
  4. Toggle on Customize for Each Post.
  5. Write content for each channel, adhering to that platform's character limit.
  6. Add media (image or video) per channel as needed.
  7. Optional: use Content AI to generate or resize copy.
  8. Click Post or Schedule.

Media gotchas

  • If media is still uploading, switching social accounts can discard the in-progress upload.
  • If media is still uploading, toggling the Customize switch can also drop the upload.
  • If a video thumbnail is processing, switching accounts or toggling Customize can interrupt thumbnail processing — you may need to reapply the thumbnail.

Important

If you turn the Customize toggle off after writing channel-specific content, the active social channel's content overrides everything else for all selected channels — and the customized content for the others is lost. Sparkforge will warn you before this happens.

Frequently Asked Questions

What if my content exceeds a platform's character limit?
Trim it for that channel. The Social Planner shows warnings or indicators when copy exceeds the platform's allowed character count, and the post won't publish to a platform if the content is over its limit.
Where does the Customize toggle live?
Inside the Create New Post composer, after you've selected at least two social channels. With only one channel picked, there's nothing to customize per channel and the toggle is hidden.
Can I use Content AI on customized posts?
Yes. Content AI works inside the per-channel composer — generate fresh copy or adapt size (small, medium, large) to fit each platform.
What happens to media if I switch channels mid-upload?
In-progress uploads can be discarded. Wait for media to finish uploading and thumbnails to finish processing before switching channels or toggling Customize.
Can I schedule a customized post for later?
Yes. Once you've written per-channel content, choose Schedule instead of Post and pick the time.
