Before you begin

Write for the destination audience first. The quality checklist offers writing advice; each network’s character and media restrictions still decide eligibility.

Follow these steps

  1. Enter the main caption, then add relevant hashtags, an optional HTTPS link and call-to-action text.
  2. Add a useful image description when attaching an image. Supply a title where the destination requires one.
  3. Select destinations and use Preview as to inspect the composed text for each account.
  4. Where a destination needs different wording, enter its account-specific caption variation and preview it again.
  5. Review Selected platform limits and the Content quality checklist, then save a draft or proceed to an authorised Post Now submission.

Fields and options

Writing fields
Main caption 1–5,000 characters; up to 30 deduplicated hashtags, each up to 65 characters. Optional HTTPS link up to 2,048; call to action up to 120.
Accessibility and title
Image description up to 400 characters. General title up to 160; Pinterest and YouTube need a title and use a 100-character limit.
Variations
An account-specific caption can be up to 5,000 characters, but the final provider-composed text must fit that network’s smaller limit.

Rules and limits

  • Hashtags, call to action and link contribute to the composed post; a base caption below a limit can still exceed it after additions.
  • The preview is a local approximation, not a guarantee of the provider’s final layout or search ranking.
  • The composer does not generate external AI content or buy advertising.

Check the result

  • Read the complete preview for every selected destination.
  • Confirm links use HTTPS and the alternative description explains the image rather than repeating a file name.

If something does not look right

  • For a limit error, shorten the complete destination text, including appended fields.
  • If a preview looks suitable but a provider rejects it, inspect the destination receipt and the network’s current content requirements.

Common questions

Do hashtags guarantee discovery?

No. The checklist helps writing quality but offers no ranking or reach guarantee.

Can each connected account use different copy?

Yes. Use that destination’s caption variation and inspect its preview.
