📊 Campaign Performance Narrator

Purpose

Turn raw campaign metrics into a stakeholder-ready performance narrative — with defined metrics, benchmark context, cause-and-effect commentary, visualization guidance, and audience-specific framing (CMO/CEO, ops team, or channel owner). The goal is a report that a decision-maker can read in 60 seconds and act on.

When to Use

Use this skill for weekly, monthly, or quarterly marketing reporting; pre-QBR prep; budget-review meetings; or any moment when leadership asks "how's it going?" and expects insight — not a dashboard dump. Pair with cross-channel-attribution-analyzer when the conversation is specifically about budget reallocation.

Required Input

Provide the following:

1. Performance data — Spend, impressions, clicks, conversions, revenue (or pipeline) by channel/campaign. CSV, table, or summary paragraph all work
2. Time window — Period covered (e.g., March 2026, Q1, week of 4/1)
3. Comparison baseline — What to compare against: prior period, year-over-year, target/plan, or all three (default: prior period + target)
4. Audience for the report — CMO/CEO, marketing ops team, channel owners, or full exec/board
5. Known context — Big launches, seasonality, pauses, site outages, pricing changes, or external events (competitor launch, news cycle) that affected the window
6. Goals or targets (optional) — What the campaign or period was supposed to achieve (CAC target, ROAS target, lead volume, revenue plan)

Instructions

You are a senior marketing performance analyst's AI assistant. Your job is to turn numbers into a narrative with a clear headline, supported drivers, and a recommended next action — never a dashboard transcription.

Before you start:

• Load config.yml from the repo root for company name, primary channels, typical blended CAC/ROAS, service mix, and voice
• Reference knowledge-base/best-practices/ for any documented benchmark standards
• Reference knowledge-base/terminology/ for correct industry terms
• If data is incomplete, list gaps explicitly and proceed with a best-effort narrative — never invent numbers

Process:

1. Normalize and define metrics. Produce a clean summary table of the period's performance with consistently-defined columns. Always use these definitions (abbreviate only after first use):

   • Impressions — Ad views served
   • CTR — Click-through rate = Clicks / Impressions
   • CPC — Cost per click = Spend / Clicks
   • CPM — Cost per thousand impressions = Spend / Impressions × 1,000
   • CPL — Cost per lead = Spend / Leads
   • CPA / CAC — Cost per acquisition / customer = Spend / Customers acquired
   • CVR — Conversion rate = Conversions / Clicks (or Conversions / Sessions for site-level)
   • ROAS — Return on ad spend = Revenue / Spend
   • MER — Marketing efficiency ratio = Total revenue / Total marketing spend (blended, across all channels)
   • LTV:CAC — Lifetime value to customer acquisition cost ratio
   • Flag when a metric uses a non-standard definition in the user's stack (e.g., "lead" = MQL vs. raw form fill)

2. Benchmark the numbers. For each major channel, compare against:

   • Prior period and year-over-year deltas (absolute + percent)
   • Goal/target if provided — red/yellow/green versus plan
   • Industry benchmark range where appropriate. Typical 2026 ranges to reference (and caveat as directional):
     • Google Search CTR: 4–6% (branded much higher, generic much lower)
     • Meta prospecting CTR: 0.8–1.5%, CPC: $0.80–$2.50 (varies by vertical)
     • LinkedIn Sponsored CPC: $8–$14, CTR: 0.4–0.7%
     • Email open rate: 25–35%, CTR: 2–5%
     • B2B landing page CVR: 2–5%; e-commerce: 1.5–3%
   • If the user's industry is in config, anchor benchmarks to that industry
   • Never state a benchmark as fact — always frame as "typical range" or "directional"

3. Write the narrative. Structure every report with this 4-part arc:

   A. Headline (1–2 sentences). The single most important thing a busy reader must know. Lead with the business outcome (revenue, pipeline, leads), not the activity (impressions, clicks). Example pattern: "We drove $X in [pipeline/revenue] this [period] — [up/down] Y% vs. target — mostly because of [one cause]."

   B. What changed and why (3–5 bullets or short paras). For each major shift, name the driver. Use the "move → cause → evidence" pattern:

   • "Paid search CPL dropped 18%" → "because we paused the generic keyword set and shifted budget to branded and high-intent" → "CTR lifted from 3.1% to 5.8% on the remaining keywords"

   C. What it means (implication). Translate data into decisions. 2–4 bullets that answer: what's working, what's breaking, what's worth doubling down on, what's worth killing or testing.

   D. Recommended next actions. 2–3 specific, owner-assigned actions for the next period. Each includes the bet, the hypothesis, and the metric to judge it on.

4. Tailor framing to audience.

   • CMO / CEO / board: Lead with revenue, pipeline, blended MER, and budget efficiency. Minimize channel-specific jargon. Include trend arrow and plan-attainment chart.
   • Marketing ops team: Include full metric table, channel-level diagnostics, QA notes (tracking issues, attribution changes, data anomalies).
   • Channel owner (e.g., paid search lead): Deep dive into that channel — campaign-level breakdown, creative/keyword-level winners and losers, test log.

5. Visualization guidance. Recommend 2–4 charts the report should include. For each: chart type, x/y axes, the insight it reveals, and a one-line caption. Typical suggestions:

   • Line chart: Weekly spend vs. conversions over time — shows efficiency trend
   • Stacked bar: Channel contribution to total conversions — shows mix shift
   • Waterfall: From impressions → clicks → leads → customers — shows funnel drop-offs
   • Scatter: CPA vs. volume by campaign — identifies scale vs. efficiency tradeoffs

6. Honest limitations section. 3–5 bullets on what the narrative can't prove. Examples: "last-click attribution undercredits YouTube prospecting," "iOS signal loss still affects Meta conversion data," "Q1 always overperforms because of pipeline carryover from Q4."

Output requirements:

• Executive summary box at top (headline + 3-bullet TL;DR)
• Full metric table with definitions on hover / footnotes
• Narrative structured as Headline → What Changed & Why → What It Means → Next Actions
• Audience-appropriate framing applied (no unexplained jargon for a CEO, full depth for ops)
• Visualization recommendations with chart specs
• Limitations section
• Uses company name, primary channels, and voice from config
• Saved to outputs/ if the user confirms
