Question 1

How long should a LinkedIn video hook be?

Accepted Answer

Aim to land your hook in the first three seconds of the video. For the post text, keep the opening line under roughly 140 characters so it reads fully before LinkedIn's "see more" truncation on mobile.

Question 2

Why do LinkedIn videos autoplay without sound?

Accepted Answer

LinkedIn plays feed videos muted by default, and viewers tap to unmute. That is why on-screen captions and a visually readable hook matter more than your voiceover for stopping the scroll.

Question 3

Should the video hook and the post caption say the same thing?

Accepted Answer

No. The spoken or on-screen hook stops the scroll in three muted seconds, while the post text earns the click before "see more." Echoing them word-for-word wastes one of your two openings.

Question 4

What makes a hook actually stop the scroll?

Accepted Answer

Specificity and tension. A scroll-stopping opener promises a concrete payoff ('the 3-word edit that doubled my reply rate') or opens a loop the reader needs closed — not a vague 'let's talk about engagement'. Front-load it: on most feeds only the first line shows before a cut-off, so the hook has to do its work there. Test several angles for the same post; the winner is rarely the one you'd have guessed.

Question 5

How long should a caption be on each platform?

Accepted Answer

Match the length to the job, then check it against the limit. Instagram captions can run long for storytelling but the hook must land in the first ~125 characters before 'more'; X/Twitter rewards tight, standalone lines; LinkedIn truncates around two lines. TikTok and Reels captions are short by nature. The reliable move is to draft freely, then trim against a live counter so nothing important gets cut.

Question 6

How many hashtags should I actually use?

Accepted Answer

Fewer, and more relevant, than the old advice. The era of 30 generic tags is over — most platforms now reward a small set (roughly 3–8) that genuinely describe the post, mixing one or two broad tags with several specific, lower-competition ones. Stuffing tags reads as spammy and can suppress reach. Put them where they don't interrupt the read: end of the caption or first comment.

Question 7

How do I write a bio that converts visitors into followers?

Accepted Answer

Treat the bio as a one-line pitch, not a résumé. Open with who you help and the outcome they get, add a single proof point, and close with a reason to follow or a clear next step. Keep it skimmable, lead with the words people would search, and reserve any styled text for one emphasised phrase. Links and @mentions stay plain so they stay clickable.
