Platform publishing rules

Beyond length and format, each platform has its own requirements: Instagram needs an image or video, Facebook posts go to a Page, Pinterest needs a board, and YouTube needs a video and a title. These are the checks publishing runs, platform by platform.

Platform rules

What each platform needs before a post can go out: the same checks publishing runs.

Instagrammedia required
  • Needs at least one image or video: text-only posts are rejected.
  • Images must be between 4:5 and 1.91:1 aspect ratio · 1080×1350 (4:5) works best for feed.
  • Comments: you can reply to existing comments, but Instagram doesn't allow starting a new top-level comment from apps.
Facebooktext-only OK
  • Posts go to a Facebook Page, never a personal profile. Connect a Page, and pick a default Page under Connections if the account has several.
  • You need Admin or Editor role on the Page.
LinkedIntext-only OK
  • Supports text-only posts, images, and video.
  • Optional title, up to 400 characters.
Google Businesstext-only OK
  • Text and image posts to your Business Profile's Updates tab.
  • Single-location accounts publish automatically; multi-location accounts pick a default location under Connections (or per post in the composer).
Xtext-only OK
  • Short captions: 280 characters max.
  • Videos over 2 min 20 sec are rejected on standard accounts.
TikTokmedia required
  • Video and photo posts both publish. Photos must be JPG or WebP, because TikTok doesn't accept PNG or GIF for photo posts.
  • On a photo post the caption doubles as the title; video posts have no separate title field.
  • TikTok enforces its own anti-spam caps (~15 posts per rolling 24h per account); pending unpublished drafts in the TikTok inbox also block new uploads.
YouTubemedia required
  • Video only. An image post can't go to YouTube. Switch the post to video or drop YouTube from its platforms.
  • Title required at publish, up to 100 characters.
Pinterestmedia required
  • Needs an image, and a board to pin to. Pick a default board under Connections (Pinterest has no auto-detect).
  • If the account has no boards yet, create one on Pinterest first, then sync connections.
  • Some websites block Pinterest saves. A pin linking to such a site is rejected.
Threadstext-only OK
  • Short posts: 500 characters max. Text-only is fine.

Common questions

Can Zolyp post to a personal Facebook profile?

No. Facebook posts go to a Facebook Page, and you need the Admin or Editor role on that Page.

Which platforms accept text-only posts?

Facebook, LinkedIn, Google Business, X and Threads. The others need an image or a video.

Why does a Pinterest post need a board?

Every Pin is saved to a board, and Pinterest has no way to pick one automatically. Choose a default board under Connections; if the account has no boards yet, create one on Pinterest and sync connections.
