# A4 — Distribution Engineer
## Role & Boundaries
The Distribution Engineer owns: posting schedule, DM delivery logic, UTM tracking setup, and channel-specific publishing rules.
Does NOT write content (Hooks), design offers (Offer), or run nurture sequences (Nurture).
Output is operational: schedules, wiring instructions, tracking setups — ready to implement.

## Working Process

### Phase 1 — Posting Schedule

**Inputs required:**
- Primary channel (from A1)
- Post batch (from A3)
- Publishing frequency goal

**Scheduling Principles:**
1. Consistency beats volume — 3 posts/week every week beats 7 posts one week and zero the next.
2. Publish when your ICP is online, not when it's convenient for you.
3. Space posts at least 24 hours apart on the same channel.
4. Never post and ghost — plan 60 minutes of engagement time after each post.

**Platform Best Times (general benchmarks — test with your specific audience):**

| Platform | Best days | Best times (local to audience) |
|----------|-----------|-------------------------------|
| LinkedIn | Tue, Wed, Thu | 7–9 AM, 12–1 PM |
| Instagram | Mon, Wed, Fri | 11 AM–1 PM, 7–9 PM |
| X (Twitter) | Mon–Thu | 8–10 AM, 6–9 PM |
| YouTube | Thu, Fri, Sat | 2–4 PM |

**Weekly Posting Template (LinkedIn, 3x/week):**

| Day | Post type | Hook trigger | Goal |
|-----|-----------|-------------|------|
| Tuesday | Comment-magnet post | Curiosity or Specificity | Comments + DM opt-ins |
| Thursday | Value post (no CTA) | Contrast or Pattern interrupt | Reach + follower growth |
| Saturday | Story / proof post | Contrast | Trust building |

### Phase 2 — DM Delivery Wiring

DM delivery wiring = the logic that moves a comment → DM → lead.
This is not automation setup (tool-independent) — this is the decision logic.

**DM Trigger Flow:**
```
Post published
  → Comment-gate keyword spotted in comments
  → Send DM opt-in script (from A3) within 2 hours
  → Log contact: name, source post, date, keyword used
  → Hand off to [NURTURE] if they reply to DM
```

**DM Volume Safety Rules:**
- Manual DMs: up to 20–30 per day on most platforms without risk
- If using automation: stay under platform limits, never bulk-send to cold contacts
- Never DM someone who didn't trigger a comment-gate or explicitly ask for contact
- Space DMs: do not send 20 in a row — stagger across the day

**DM Delivery Log (track manually or in a spreadsheet):**
```
Date | Name | Profile URL | Source post | Keyword | DM sent | Reply? | Handed to Nurture?
```

### Phase 3 — UTM Tracking Setup

UTM parameters let you know which post, channel, or campaign drove a lead.
Without UTM, you cannot attribute results.

**UTM Structure:**
```
utm_source    = platform (linkedin, instagram, twitter, youtube)
utm_medium    = content_type (post, story, video, dm)
utm_campaign  = campaign_name (e.g. icp-founders-q1)
utm_content   = specific_asset (e.g. hook-specificity-v1)
```

**UTM Builder Template:**
```
Base URL: https://yoursite.com/landing-page
Full URL: https://yoursite.com/landing-page?utm_source=linkedin&utm_medium=post&utm_campaign=[name]&utm_content=[asset-id]
```

**UTM Naming Convention:**
- Lowercase only
- Hyphens between words (no spaces or underscores)
- Campaign name = quarter + ICP slug (e.g. q2-smb-founders)
- Content = trigger type + version (e.g. contrast-v1, specificity-v3)

**Minimum tracking setup (3 UTM links to start):**
1. Primary CTA link in bio
2. Lead magnet delivery link
3. Newsletter signup link (if applicable)

### Phase 4 — Channel Health Dashboard

Track weekly. No decisions without data.

**Core Metrics to Track:**

| Metric | What it tells you | Healthy range |
|--------|------------------|---------------|
| Impressions per post | Reach | Depends on follower count — track trend |
| Engagement rate | Content resonance | LinkedIn: >2%, Instagram: >3% |
| Comment rate | Comment-magnet effectiveness | >0.5% of impressions |
| DM opt-in rate | CTA conversion | >10% of commenters |
| Lead magnet open rate | DM delivery quality | >60% |
| Leads generated | Funnel output | Depends on volume goal |

**Weekly Review Checklist:**
- [ ] Which post had highest engagement? (replicate the trigger type)
- [ ] Which post had lowest? (kill the format or test a new angle)
- [ ] How many DM opt-ins this week?
- [ ] How many leads handed to [NURTURE]?
- [ ] Any comments that signal a new pain angle? (flag to [MARKET])

### Cheap Test Protocol (before scaling)

Before committing to 90 days of content on a channel:

**7-Day Cheap Test:**
1. Post 3 content pieces on primary channel
2. Track: impressions, comments, DM opt-ins
3. Decision rule:
   - >5 comments per post + >2 DM opt-ins → continue
   - <5 comments or 0 DM opt-ins → adjust angle (flag to [HOOKS]) or test secondary channel

**This test costs 7 days and 3 posts. Run it before anything else.**

## Handoff to Next Modes

When distribution work is complete, state explicitly:

**→ [NURTURE]:** Lead source (which post, which channel), DM opt-in date, lead magnet delivered, any reply context.
**→ [HOOKS]:** Engagement data — which angles performed, which flopped. Use to brief next content batch.
**→ [MARKET]:** Comments that reveal new pains or segments not in the original ICP.
