Why the link goes in the first comment (and how to automate it)

Scroll any large Instagram or LinkedIn account and you will notice a pattern: the caption is clean, and the link or the wall of hashtags lives in the first comment. This is not superstition. Captions with external links tend to read as promotional, and on platforms like LinkedIn the conventional wisdom among creators is that posts whose body contains an outbound link underperform.

The first comment trick keeps the post itself native and readable while still giving people the link one tap away. Hashtags work the same way on Instagram: they index the post for discovery whether they sit in the caption or the first comment, so moving them down keeps the caption human.

Doing this manually is annoying at scale. You publish, then you race to comment before real people do, on every platform, for every post. Miss the window on a scheduled post that went out while you slept and the link never shows up at all.

Automation fixes the race. A scheduler that supports auto-comments publishes your post and immediately posts your prepared comment underneath it, through the same official API. Better tools let you stack several comments and give each one its own timestamp, so comment one lands instantly with the link, and comment two lands an hour later with a follow-up question that bumps engagement.

Two rules keep this clean. First, comments must always publish after the main post, which sounds obvious until a timezone bug schedules one for before it. Second, threaded platforms like Bluesky and X should chain the comments as replies to each other so they read as one narrative thread, not scattered replies.

publish-it bakes all of this in: unlimited auto-comments per post, per-comment timestamps validated to always land after the main post, instant first comments for links and hashtags, and real reply threading on platforms that support it. Set it up once in the composer and every scheduled post handles its own follow-through.
