Draft social captions from a published blog post

Pulls a different angle for each platform from one published post (LinkedIn, X, Instagram) instead of posting the same caption everywhere, while keeping enough back that people still have to click through.

You handle social promotion for a WordPress agency's blog. The post "[We Cut a
Client's Page Load Time From 6.2s to 1.4s: Here's the Exact Checklist We Used]" just
went live and needs captions for LinkedIn, X, and Instagram.

POST SUMMARY: [a case study post with a 10-item technical checklist, the headline
stat is the 6.2s to 1.4s load time improvement, includes 2 before/after
screenshots]
BRAND VOICE: [direct, a little technical, no corporate hashtag spam]

Work through this before drafting:
1. Pick a different lead angle per platform instead of copy-pasting one caption
   everywhere. LinkedIn's audience responds to a professional insight with a number
   (the 6.2s to 1.4s result as a credibility signal), X rewards a punchy, single
   contrarian or surprising claim, Instagram needs the caption to support a visual
   (the before/after screenshot) rather than lead on its own.
2. Edge case: don't give away the full 10-item checklist in any caption, that's the
   post's whole payoff. Tease one specific item, the one most likely to surprise
   someone, not the most obvious one, to create a real reason to click through,
   rather than a vague "check out our new post" caption that gives no one a reason
   to leave the feed.
3. Match format conventions: write the X post as a short thread starter (under 280
   characters, ending on a hook, not a summary) since a single dense post with the
   whole story removes any reason to click. Write the LinkedIn post as 3-4 short
   lines with the stat up top. Write Instagram as a caption built around the
   screenshot, with 3-5 relevant hashtags at the end, not stuffed mid-caption.
4. Match brand voice throughout, direct and specific, no corporate hashtag spam
   regardless of platform norms.
5. Since the 6.2s-to-1.4s number will get quoted out of context on social, make sure
   at least one caption per platform notes it's from a specific case study, not a
   universal promise, so it doesn't read as an overclaim divorced from its source.

Draft all three captions with platform labels, plus one suggested hashtag set for
Instagram.

The temptation with social captions is to write one good caption and paste it everywhere, which is exactly why so much brand content on social reads identically across platforms. Picking a genuinely different angle per platform, not just a shorter or longer version of the same caption, is what actually earns different results on each one.
