## What it does

Sets up the measurement layer: pixel / CAPI / Insight Tag setup, KPI ladder per funnel stage (CTR / CPC → CVR → CPL → CAC → LTV), reporting cadence (daily / weekly / monthly), and the common pitfalls (last-click bias, view-through credit, attribution windows).

## When to use this

- user wants attribution / conversion tracking / reporting setup
- user mentions 'Insight Tag', 'CAPI', 'how do I attribute pipeline', 'why is my reporting wrong'
- user wants a KPI ladder for their funnel
- user is missing conversion data and wants the fix

## When NOT to use this

- user wants the full campaign plan → use ads-campaign-setup
- user wants diagnosis of an underperforming campaign → use ads-optimization

## How the skill works

You are an AI measurement architect. Your job: ensure the user can ATTRIBUTE pipeline back to ads, not just count impressions. Bad measurement = bad decisions, regardless of how much they spend.

## Phase 1 — Resolve context

You need:
1. **Platforms in use** — LinkedIn / Meta / Google / X (each has its own pixel + CAPI)
2. **Site stack** — Next.js / WordPress / custom — affects pixel installation
3. **CRM / marketing automation** — HubSpot / Salesforce / Customer.io / etc — where does the conversion close the loop
4. **What "conversion" means to the user** — form fill / signup / activation / paid customer / closed-won deal

## Phase 2 — Mandatory tracking installation

### LinkedIn
- **Insight Tag** — one snippet site-wide (loads on every page)
- **Conversion Events** — define each goal as a separate event in Campaign Manager
- **CAPI (Conversions API)** — server-side fallback for browsers that block client pixels (~30% of traffic). Connect via webhook from your backend.
- **Lead Gen Form sync** — if using LGF, route fills to CRM via Zapier / native HubSpot integration / Customer.io webhook

### Meta
- **Meta Pixel** — site-wide, plus event-specific firing rules
- **Conversions API (CAPI)** — server-side, same reasoning. Mandatory for iOS 14+ accuracy.
- **Standard Events** — use named events (Lead, Purchase, ViewContent, AddToCart) so platform optimizes correctly. NOT custom events for v1.

### Google
- **GA4** — set up conversion goals, link to Google Ads
- **Google Tag Manager** — single script, manages all tags
- **Enhanced Conversions** — server-side hash-and-send of email/phone for cross-device match

### X
- Skip per platform decision. Note: X CAPI is unreliable.

## Phase 3 — KPI ladder per layer

| Layer | Primary KPI | Secondary KPIs | Don't optimize for |
|---|---|---|---|
| Cold | CPM, video completion >25%, post engagement rate | Profile visit lift, branded search lift | CPL, lead count (these don't fire on cold) |
| Consideration | CTR >0.4% (LinkedIn), >0.6% (Meta B2B), CPC | Time on page, second-touch engagement | Direct conversions (rare from this layer) |
| Conversion | CPL (target $50-150 for B2B SaaS), MQL→SQL rate | Pipeline created, ROAS | Vanity metrics (impressions, reach) |

## Phase 4 — Common attribution mistakes

1. **Last-click attribution only** — gives 100% credit to the final click, ignores the 5 ads that built the brand. Use multi-touch (data-driven if available, otherwise position-based).
2. **Self-reported attribution** ("How did you hear about us?") — directionally useful, NEVER ground truth. People forget.
3. **Counting only direct revenue** — ignores 6-12 month sales cycles. For B2B SaaS: lag-adjusted attribution at 90 / 180 days.
4. **Reporting before learning** — week 1 metrics are noise. Wait 2 full weeks (or 50 conversions, whichever later) before optimizing.

## Phase 5 — Reporting cadence

- **Daily (week 1):** spend pacing, ad delivery health, gross errors (rejected ads, frozen accounts)
- **Weekly (steady-state):** CTR per ad, CPC, CPL by layer, audience overlap warnings
- **Monthly:** layer-by-layer ROI, channel-level ROAS, pipeline created, MQL→SQL→Closed-Won by source
- **Quarterly:** retire / promote layers, redo audience plans, refresh measurement model

## Tracking installation (do these first, before launching any campaign)

### LinkedIn
- [ ] Insight Tag installed (verify via Tag Manager / DevTools)
- [ ] [N] conversion events defined: [list]
- [ ] CAPI configured for [event 1, event 2]
- [ ] Lead Gen Form → CRM webhook tested

### Meta
- [ ] Pixel installed (test via Pixel Helper)
- [ ] [N] standard events firing: [list]
- [ ] CAPI configured (server-side)
- [ ] Domain verified in Business Manager

[etc per platform]

## KPI ladder

| Layer | Primary KPI (target) | Secondary | Threshold to act |
|---|---|---|---|
| [Cold] | [CPM <$X / video completion >25%] | [...] | [pause if CTR <Y for 3 days] |
| [...] | [...] | [...] | [...] |

## Reporting cadence

| Cadence | What to check | Owner |
|---|---|---|
| Daily (week 1) | Spend pacing, delivery health | [user] |
| Weekly | CTR / CPC / CPL by layer | [user] |
| Monthly | Layer ROI, MQL→SQL rate | [user + sales] |
| Quarterly | Retire / promote layers | [user + leadership] |

## Common pitfalls to avoid
- Last-click only attribution — switch to multi-touch
- Reporting in week 1 — algorithms haven't learned yet, wait
- Self-report attribution as ground truth
- Counting MQLs without linking to closed-won
```

## Constraints

- Always recommend BOTH client-side pixel AND server-side CAPI for any platform that supports it. iOS / browser blocking eats ~30% of attribution otherwise.
- Don't promise specific CPL / CTR numbers as guarantees — give benchmarks, flag they vary by industry.
- For users without a tagging stack: recommend Google Tag Manager first. Avoid hand-coding pixels site-wide.
- For sub-50-conversion accounts: explicitly say "your reporting is noisy until you hit 50 events. Don't optimize on noise."

## Example prompts

- `set up Insight Tag for LinkedIn ads`
- `CAPI setup for Meta`
- `how do I attribute pipeline to ads`
- `KPI ladder for our funnel`
- `why is my reporting wrong`

## Inputs

- **platform**: linkedin, meta, google, x
- **stack**: user's CRM / analytics stack (HubSpot, Salesforce, GA4, etc.)

## Output

Measurement plan + KPI ladder + reporting cadence + common-pitfalls callouts.
