| 3 | ## Purpose |
| 4 | |
| 5 | Design a systematic creative testing framework that maximizes learning velocity while maintaining statistical rigor across advertising platforms. Produces a complete testing playbook with variable prioritization, sample size requirements, iteration cadence, and documentation standards for continuous creative optimization. |

| 7 | ## Input Required |
| 8 | |
| 9 | The user must provide (or will be prompted for): |
| 10 | |
| 11 | - **Ad platform(s)**: Where ads are running — Google Ads, Meta Ads, LinkedIn Ads, TikTok Ads, programmatic DSPs, Pinterest, X/Twitter, or multi-platform |
| 12 | - **Creative types available**: What formats can be produced — static image, video (short-form/long-form), carousel, text-only, responsive display, HTML5, playable, or collection ads |
| 13 | - **Monthly ad budget allocated to testing**: How much budget is available specifically for creative experimentation vs. proven performers |
| 14 | - **Current top-performing creative**: Description or reference to the best-performing ads currently running, including their key metrics |
| 15 | - **Learning goals**: Which creative elements need optimization — headlines, imagery, CTA copy, video hooks, color palette, offer framing, social proof, format type, or ad copy length |
| 16 | - **Audience segments for testing**: The audience groups available for testing — prospecting, retargeting, lookalike, interest-based, demographic, or custom segments |
| 17 | - **Campaign objectives**: What the ads are optimized for — awareness (impressions/reach), consideration (clicks/video views), or conversion (leads/purchases/ROAS) |
| 18 | - **Historical creative performance data**: Optional — past test results, creative fatigue patterns, seasonal performance variations, and known winners/losers |
| 19 | - **Brand guidelines constraints**: Visual identity rules, messaging restrictions, mandatory disclaimers, or approval bottlenecks that affect creative production speed |
| 20 | - **Testing timeline**: How long the testing program should run — single sprint (2-4 weeks), quarterly roadmap, or ongoing evergreen program |
| 21 | |
| 22 | ## Process |
| 23 | |
| 24 | 1. **Load brand context**: Read `~/.claude-marketing/brands/_active-brand.json` for the active slug, then load `~/.claude-marketing/brands/{slug}/profile.json`. Apply brand voice, compliance rules for target markets (`skills/context-engine/compliance-rules.md`), and industry context. **Also check for guidelines** at `~/.claude-marketing/brands/{slug}/guidelines/_manifest.json` — if present, load restrictions and relevant category files. Check for custom templates at `~/.claude-marketing/brands/{slug}/templates/`. Check for agency SOPs at `~/.claude-marketing/sops/`. If no brand exists, ask: "Set up a brand first (/digital-marketing-pro:brand-setup)?" — or proceed with defaults. |
| 25 | 2. **Define testing variables**: Catalog all testable creative elements — headline copy, body copy length, CTA text and color, hero image subject, image style (photo vs. illustration vs. UGC), video hook (first 3 seconds), video length, ad format (static vs. carousel vs. video), color palette, offer framing (discount vs. value vs. urgency), social proof type (testimonial vs. stat vs. badge), and layout composition. |
| 26 | 3. **Prioritize variables by expected impact and ease**: Score each variable on a 2x2 matrix of expected performance impact (high/low) and production effort (high/low). Rank variables so the team tests high-impact, low-effort elements first. Use historical data and platform benchmarks to inform impact estimates where available. |
| 27 | 4. **Design testing matrix**: Build the variable-by-variant grid — for each priority variable, define 2-4 variants to test against the current control. Ensure tests are isolated (one variable per test) unless running deliberate multivariate experiments. Map each test to the appropriate audience segment and platform. |
| 28 | 5. **Calculate sample size per variant and minimum budget**: Compute the required conversions per variant with `python "${CLAUDE_PLUGIN_ROOT}/scripts/sample-size-calculator.py" --baseline-rate {rate} --mde {mde} --mde-type relative --significance 0.95 --power 0.80` (a "10-20% relative lift" is `--mde 0.10`-`0.20` with `--mde-type relative`; use `--mde-type absolute` if the target is stated in percentage points — the two differ by ~40× at a 5% baseline). Translate sample size into minimum budget per test based on current CPM/CPC rates. |
