Question 1

What's the character limit for a Bluesky comment?

Accepted Answer

Replies share the standard 300-character post limit. Bluesky counts by grapheme, so one emoji or accented letter uses a single character, but pasted links count their full length unless you hyperlink shorter text.

Question 2

Do hashtags and mentions work in Bluesky replies?

Accepted Answer

Yes. Both are clickable facets you can add inside a reply, and each still counts toward the 300-character limit. Mentions notify the person; hashtags feed into search and any custom feeds tracking that tag.

Question 3

Can you edit a comment after posting on Bluesky?

Accepted Answer

Bluesky rolled out post editing, so replies can be edited for a limited window, with prior versions kept in history. If editing isn't available to you, delete the reply and repost the corrected version instead.

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.
