Field notes
Playbooks, teardowns and the occasional argument — everything we have learned helping creators grow across every major platform.
Somebody taps a bio link seconds after watching one specific thing, looking for that thing. Almost every link page is ordered by what its owner values instead.
The advice is everywhere and the reason given for it is usually wrong. There is a real argument for rotating, and it is not the one about being flagged.
Eighty characters on TikTok, a thousand on a YouTube channel. The numbers, what happens when you exceed them, and the two networks that quietly delete your line breaks.
No platform limits the text on a carousel image. What limits it is whether anybody can read it at feed size, which makes the answer arithmetic rather than a rule.
Instagram publishes two separate rulebooks. One decides whether a post stays up; the other decides whether anyone who does not follow you ever sees it, and it never sends a notification.
Instagram writes an automatic description for every image whether you do or not. Yours replaces it, you get 100 characters, and the field is three taps deep.
Instagram line breaks collapse because the composer strips trailing whitespace. Put a printable-but-blank character on each empty line and the paragraphs survive.
Price on reach times a niche rate times your engagement band — never on followers alone. Quote three numbers: the ask, the fair rate, and the floor you walk away below.
The picture rendered fine when you pasted it and is a broken icon now. The expiry was in the URL the whole time — here is how to read it.
Instagram publishes a larger copy of every public post's picture so link cards can render it. Here is how to reach it, and why the link stops working.
Draw an Instagram post card with the caption cut exactly where the feed cuts it, so you can see which sentence disappears behind "more" before you publish.
Instagram removed the embed button from the web interface, but the embed itself still works. Here is how to build the code from a post URL, in both forms.
