Make it fit each channel
Quick recallHow many asks should one post have?Think of your answer, then open.
One. A reader who got to the end is ready to do one thing. Give them one.
The same post can go to several channels, but each reads a little differently. Postfjord writes one base text and lets you change it per channel where it matters.
What changes where
- Instagram: the picture carries the post. Captions can be up to 2,200 characters but only the first lines show. Hashtags go at the end or in the first comment.
- Facebook: a link in the text works, and a little longer is fine.
- Threads: up to 500 characters and one topic tag. Short, like a reply to a friend.
- LinkedIn: up to 3,000 characters. Longer works if the first line earns it. Say what you learned, not only what you sell.
Channel variants
Write the base text first. Open a channel's tab and write a variant only where it needs one. Each tab shows a live preview and warns when the text is too long or the media does not fit. Claude can rewrite the base for one channel, shorten it or suggest hashtags. From a brief with several channels selected, you get one version per channel.
A few relevant hashtags beat thirty generic ones. On Instagram, put them in the first comment.
That is the course: a first line that stops the scroll, a brief with your own detail, one next step, and a fit for each channel.
Do it
- Select two or more channels and generate a draft from a brief.
- Open the Threads tab.
- Check the preview shows no warning and reads in one breath.
