Metrics to watch — Hook hold (3-second view %), CTR ≥ 0.9 %, SQL rate ≥ 8 % of clicks.

Resize to 1:1 and 16:9 in CapCut.
Upload to LinkedIn Campaign Manager, audience = job titles + 1–5 competitor names.
Add UTM ?utm_source=linkedin&utm_campaign=video_ad&utm_content=pain_1.

Practical Tips & Cautions
Open with the pain—not your logo.
Show product inside 3 seconds after hook.
Subtitles are non-negotiable—85 % watch silent.
One CTA only; multiple links kill conversions.
Test 3 hooks (pain, stat, competitor slam) in separate $50 ad sets.
Tight framing for mobile—face + screen share 50/50.
Beware jargon—if your ICP says “ETL,” use it; otherwise say “sync data.”
Founders often miss this — upload the same video to YouTube, LinkedIn, and X but change the first line of copy to match each platform’s native tone; the algo rewards native text, not copy-paste.
FAQs
How long should a b2b saas ad video be?
15–30 s for feed placements; 45 s max if you need a mini-demo.
Which channel converts best?
LinkedIn feed for $5–20 k ACV deals; YouTube TrueView for volume top-of-funnel.
What’s the realistic cost?
$0 if you record screen-only; $300–500 if you outsource editing; $1 k+ if you add studio shots.
Do I need an actor or can I use the founder?
Founder works until Series A—authenticity > production value.
What metrics actually matter?
3-second view rate (hook), CTR (creative-market fit), SQL rate (pipeline). Ignore vanity views.
Can I repurpose the same clip for organic?
Yes—strip the CTA, add value-first hook, post natively on LinkedIn and YouTube Shorts.
