What is the first comment on a LinkedIn post?
The first comment is a comment the author adds to their own post at publication, conventionally used to carry links, sources, or a follow-up question without putting them in the post itself.
Also called: first comment strategy, comment below the post, link in the comments.
It exists because of a trade-off in the post body. Links tend to reduce how far a post travels, since readers who leave do not engage, but the link is often the point. Putting it one layer down keeps the post clean and the resource one tap away.
It also gives the thread a starting point. An empty comment section is a harder thing to join than one with a comment already in it, so an opening comment that asks something specific measurably raises the chance a real conversation begins.
The useful discipline is writing it at the same time as the post rather than remembering afterwards. A first comment added an hour late has missed the window when the post was being tested and the thread was worth seeding.
One honest caveat: LinkedIn does not let you pin your own comment to the top of your post, and tools implying otherwise are describing something the platform does not offer. What you control is being first, which usually places it well.
Common questions.
Can you schedule or pin a first comment on LinkedIn?
No. LinkedIn does not provide an API for posting or pinning a comment on your own post, so any tool claiming to schedule or pin one is describing something the platform does not support. The workable version is having it written and ready to paste.
Should links go in the post or the first comment?
The comment, in most cases. Links in the body reduce distribution because readers leave instead of engaging, and a link one layer down costs the interested reader almost nothing.
