## 360Brew Profile Validation (January 2026)

**This is the most significant LinkedIn algorithm change since the platform launched.**

### The Fundamental Shift

**Before January 2026:** Post something -> Goes to 10% of your audience -> LinkedIn tracks engagement -> Decides if more people should see it.

**After January 2026:** LinkedIn auditions you FIRST. Before your post goes anywhere, the algorithm scans your profile to determine if you're actually qualified to talk about the topic.

### The 360Brew Scoring System

LinkedIn's 150B parameter foundation model evaluates **five criteria** before your post reaches anyone:

| Criteria | What It Checks | Impact if Missing |
|----------|----------------|-------------------|
| **About Section** | Does it establish expertise on this topic? | High - first signal of credibility |
| **Experience Section** | Do you have relevant background with impact statements? | High - proves you've done the work |
| **Content History** | Have you posted about this topic before? | Medium - consistency signal |
| **Network** | Are you connected to other professionals in this space? | Medium - social proof |
| **Engagement Patterns** | Do you comment on posts about this topic? | Medium - active participation |

**If these don't align with your post topic, your reach gets throttled. Hard.**

### Strategic Implications

**Before you post again, audit your profile:**

Ask yourself: "If LinkedIn's AI read this, would it believe I'm an expert on the topics I post about?"

If the answer is no, fix that first.

## Profile Optimization Checklist

### About Section (CRITICAL)

Your About section is the **first signal** telling 360Brew what you're qualified to discuss.

**Structure for optimization:**

**First 2-3 lines (visible without "see more"):**
- Front-load your specific expertise claim
- Use domain-specific terminology
- State WHO you help with WHAT problem

**Full About section:**
```
[Specific expertise claim with domain terminology]
[WHO you help + specific RESULT you deliver]

[Your story - brief, relevant to your expertise]
[Credentials that validate your expertise]
[Frameworks/approaches you use]
[How to connect/work with you]
```

### Experience Section (HIGH IMPACT)

Transform each role with impact statements, not task lists:

- "Deployed first Copilot Studio agent handling 40% of internal inquiries"
- "Built RAG solution processing 12,000+ feedback entries"
- "Achieved documented 968% ROI on AI initiatives"

### Headline Formula

WHO you help + RESULT you deliver

Strong: "Helping public sector leaders implement AI that actually works | AI Advisor @ Statens vegvesen"

## Voice Training

### Building a Voice Profile

The voice-trainer agent analyzes your writing samples to identify:

1. **Sentence structure patterns** -- Short/long mix, fragments, questions
2. **Word choice signatures** -- Technical depth, jargon level, unique phrases
3. **Hook style** -- How you naturally open posts
4. **Storytelling approach** -- How you construct narratives
5. **Tone signature** -- Formal/informal, humorous/serious, provocative/measured

### Voice Drift Detection

Over time, content can drift from your authentic voice -- especially when using AI tools.

**Warning signs:**
- Posts feel "corporate" or "polished but generic"
- Comments don't match your post voice
- Engagement drops despite consistent posting
- You wouldn't say this out loud

**Prevention:**
- Quarterly voice audits (use voice-trainer agent)
- Read posts aloud before publishing
- Maintain voice samples in `assets/voice-samples/`
- Compare drafts against your voice profile

### Voice Samples

**Rule:** Always read `assets/voice-samples/` before generating content. This directory contains reference posts that represent the user's authentic voice.

## Content Differentiation

### The Originality Framework

The differentiation-checker agent evaluates content across five dimensions:

1. **Angle uniqueness** -- Is this perspective novel?
2. **Evidence quality** -- Are you citing unique sources/experiences?
3. **Framework originality** -- Are you creating or borrowing frameworks?
4. **Voice distinctiveness** -- Would readers know this is you without the byline?
5. **Value density** -- Is every sentence earning its place?

### Commodity Content Detection

**Red flags for commodity content:**
- Could be written by anyone in your field
- Contains only widely-known advice
- Uses the same examples everyone uses
- Lacks personal experience or data
- No contrarian or unique angle

**Fix strategies:**
- Add personal data/experience
- Take a contrarian position (and defend it)
- Combine two seemingly unrelated domains
- Go deeper than surface-level advice
- Share what you learned from failure, not just success

## Common Patterns

**User: "Does this sound like me?"**
1. Load voice profile and samples
2. Compare draft against voice signatures
3. Identify specific drift points
4. Suggest targeted edits to restore voice

**User: "Is this original enough to post?"**
1. Run differentiation check
2. Search for similar published content
3. Score across five dimensions
4. Suggest strategies to increase uniqueness
