Missing CTA

Your platform shows what happened. We show why.

CTR and ROAS tell you the outcome. They tell you nothing about the causal factors in the creative. AdZhi starts with the raw audio waveform — measuring pitch, energy, and delivery quality at the signal level — so you know exactly what to fix before you run it.

  • Pitchexpressiveness, monotony score, emphasis patterns, inflection quality throughout the ad
  • Energywhere the ad's energy peaks and drops, CTA momentum score, dynamic range
  • Voice credibilityhow trustworthy the voice sounds, clarity, warmth, professionalism rating
  • Disfluencyfiller words flagged by exact position and timestamp — know if an 'um' is killing your hook before you run it
  • Audio environmentbackground noise, music bed presence, signal clarity
  • Rhythmpacing, pause patterns, thought group structure, cadence regularity

CTA at 00:24 is delivered 32% quieter than the ad average. Re-record this section with more energy. This is where you lose the conversion.

Every persuasion act scored. Every gap named.

AdZhi maps the entire script to named persuasion acts — Hook, Problem, Solution, Social Proof, CTA — scores each one, and identifies exactly what's missing and what the absence costs you.

  • Acts scored individually: Hook, Problem, Agitate, Solution, Social Proof, CTA, Story, Credibility
  • Structure classified and scored 0–10: AIDA, PAS, Hook-Story-CTA, Direct Response, and more
  • Missing elements flagged explicitly: not just what's there, but what should be
  • Acoustic signals feed into the verdict: "hook lands well but CTA is delivered flat"
  • Timestamped so every finding maps back to the exact moment in the ad

Social proof Missing
Missing: Social proof, explicit CTA. Add one credibility signal and a direct ask. These are the most commonly missing elements in underperforming ads.

Not a score. A brief your creator can act on today.

Three rewrite variants with specific delivery direction, then a ready-to-send creative brief. Not "improve your CTA" — "re-record from 00:24 with 20% more energy and a direct imperative verb."

  • Rewrites informed by every acoustic signal: "raise energy 20% at the CTA"
  • Delivery notes target the specific problems found: not generic voiceover advice
  • Brief includes: one-liner, keep/fix list, hook direction, CTA direction, word count target, production notes
  • Word count calibrated to the pacing of the original recording
  • PDF export: hand directly to a creator or include in a client deck

Creative brief
The most important change is a single explicit CTA delivered with confidence. The structure is solid, just the close is letting it down.
Hook direction Keep the question. Add a one-beat pause after it. Let it land.
Vocal direction Raise energy 20–25% at "shop now". Stand up when you record it.
Word count 72 words · target 110 WPM
Add One social proof claim before the CTA. A number works best.
Keep Audio quality is excellent. Don't re-record unnecessarily.

Why acoustic intelligence compounds over time

A well-funded competitor can integrate a speech API in a sprint. What they can't replicate in 3 months — or 12 — is what accrues from operating the stack on real ad data.

01 — Data flywheel

Per-account correlation intelligence

Every account that logs ROAS and CTR against AdZhi scores trains a per-account correlation model. Over time, AdZhi learns which specific acoustic signals predict performance for that audience and category. A competitor starting from zero has none of this. Account-specific intelligence cannot be copied — it has to be earned, data point by data point.

02 — Calibration depth

Ad-specific acoustic tuning — not generic speech analysis

AdZhi measures 8+ acoustic features — spectral centroid, pitch variance, shimmer, zero-crossing rate, RMS energy, MFCCs, and more. Getting these features right for short-form ad creative — where a 3-second CTA drop is catastrophic — is different from general speech analysis. This calibration has been tuned iteratively against ad-specific patterns. Getting there requires the data, not just the algorithm.

03 — Benchmark library

Context-free scores are worthless

A hook score of 7.2 means nothing without a reference population. AdZhi's fleet-wide benchmarks across all analyses give every score a percentile context — "top 18% of DTC skincare hooks analysed." A new entrant has no benchmark library. Their first score is context-free. Their hundredth score is still context-thin. Benchmarks require volume and time, not just engineering.

04 — Switching cost

Institutional knowledge encoded in score thresholds

A team that has used AdZhi for six months has made decisions based on its output format. "We don't run anything with a hook below 6." "CTA intensity under 40 goes back for re-record." These internal norms are encoded against AdZhi's specific scoring system. Switching to a new tool means recalibrating every threshold, every norm, and every brief template the team has built. That friction compounds with every passing month.

We're not claiming this moat is impenetrable — we're claiming it takes longer than 3 months to replicate. The data flywheel, benchmark library, and per-account intelligence are real structural advantages that widen as AdZhi is used.
