Best Practices for Captions, Hooks and CTA
Captions, Hooks, and CTAs That Work
Updated: 2026
Three pieces of copy do 90% of the work in social content: the hook (gets the click), the caption (holds attention), and the CTA (drives action). Here's how to brief Mavic for each.
Hooks
A hook earns the next 1 second. If yours doesn't, nothing else matters.
Prompt:
Give me 15 hooks for [topic]. Mix formats: question, contrarian, stat, story, list, POV. Max 10 words each. Voice: @Writing Style.
Hook formats that consistently work:
Format | Example |
|---|---|
Contrarian | "Stop posting daily. Do this instead." |
Stat shock | "94% of brand pages get under 100 views. Here's why." |
List promise | "5 things I'd do if I started over today." |
POV | "POV: your launch flopped and you don't know why." |
Question | "Why does no one click your CTA?" |
Story open | "Last month I lost a $40k client. Here's what I learned." |
Mistake call-out | "If you're doing X, stop." |
Test discipline: Generate 15. Cut to 5. Post 3 across the week. Track saves and shares — those are the hook signal, not likes.
Captions
Captions are not blog posts. They're a hook + a payoff + a CTA — usually under 150 words.
Prompt:
Write a caption for [topic]. Structure: hook (1 line) + 1 line break + 2-3 short paragraphs + CTA. Use @Writing Style. Add 5 niche hashtags.
Caption rules:
- First line is the only line most people see — make it standalone
- Use line breaks between every 2 sentences (mobile readability)
- One CTA at the end — don't bury it
- Hashtags: 3-5 niche beats 30 generic
The "save this post" trick: End with a save trigger like "Save this for your next [moment]." Saves are the strongest reach signal.
CTAs
Most CTAs are vague. "Click the link" doesn't work — say what's behind the link and what they'll get.
Prompt:
Give me 10 CTA variations for [offer]. Mix: low-friction (DM, comment), medium (link tap, save), high (book, buy). Each under 12 words.
CTA quality ladder:
- Low friction (engagement) — "Comment 'GUIDE' and I'll send it"
- Medium friction (lead) — "Tap the link to grab the free template"
- High friction (purchase) — "Book your strategy call — link in bio"
Match CTA to platform:
- Instagram feed/Reels: "Comment X" (DMs > link taps in feed)
- Stories: "Swipe up" / link sticker
- LinkedIn: "Read the full breakdown" + comment prompt
- X: thread CTA at end ("Bookmark this for later")
- Email: button copy in 3-5 words ("Get the template")
Test discipline
Treat hooks, captions, and CTAs as variables. In one week, change ONE per post and track the result. After 4 weeks you'll know what your audience responds to — feed those learnings back into your Writing Style in Brand DNA so every future post benefits.
