Hook Rate Autopsy: Diagnosing Why 4 TikTok Ad Openers Would Flop
Objective: Given 4 synthetic TikTok ad opening scripts and configs, correctly identify which would fail the Hook Rate benchmark, the native-creative standard, or the campaign-structure rules, without seeing performance data first.
You're a freelance TikTok ads consultant reviewing draft creative and ad group setups for RXBAR before they go live. Production budget is already spent; you only get to flag issues before launch.
Read each specimen cold. Decide pass/fail against the lesson's hook, native-creative, and campaign-structure standards, then check your calls against the answer key.

The process
Specimens to review
Would this opener survive TikTok's Hook Rate and native-creative standards? List every defect you find.
SCRIPT 1 — 'Protein On The Go' 0:00-0:03 Slow zoom on RXBAR logo, brand jingle plays 0:03-0:08 Voiceover: 'Introducing RXBAR, the protein bar made with real ingredients' 0:08-0:15 Product shot rotating on white background 0:15-0:30 Text overlay: '6 ingredients or less. Available now.'
Specimen: synthetic, realistic
Check this opener against the hook and native-creative standards. Are there any remaining issues even though the hook itself works?
SCRIPT 2 — 'I Ate 30 Protein Bars So You Don't Have To' 0:00-0:02 Handheld phone footage, creator already mid-bite, chewing, slightly shaky camera 0:02-0:04 Text overlay pops in: 'Rating every RXBAR flavor (ranked worst to best)' 0:04-0:20 Creator tastes and reacts to 5 flavors, casual tone, trending audio under it 0:20-0:28 'Link in bio, my #1 pick is restocked'
Specimen: synthetic, realistic
Review this ad group setup before it launches. What would you flag?
AD GROUP CONFIG — 'RXBAR Retarget Push' Audience: Interests (Health & Fitness, Protein Supplements) + Behavior (Recently viewed food delivery apps) + Lookalike (1% of website purchasers, US only) Estimated audience size: 180,000 Creative variations uploaded: 1 Budget: $50/day Bidding: Lowest Cost
Specimen: synthetic, realistic
Is this a defect-free plan, or is something still missing before launch?

Halo Top, Spark Ad creative audit (excerpt) SCRIPT: 'Pint Nutrition Facts in 3 Seconds' Hook (0:00-0:03): PASS — opens on a spoon scraping the bottom of an empty pint, no logo Native fit: PASS — vertical, handheld, trending audio CTA/Pixel: FLAG — no trackable link moment before video ends Verdict: Launch-ready pending CTA fix
Success criteria
You're done when you can:
- Correctly identifies both critical defects in Script 1 (no hook, corporate feel)
- Does not flag Script 2's mid-action opener as a defect (recognizes the correct pattern)
- Flags the over-targeted ad group's narrow audience and single-creative-variation issues
- Catches the missing Spark Ad authorization step in Script 4
