KOL Discovery Engine

KOL Discovery

Find Key Opinion Leaders in any domain by searching LinkedIn posts for prolific, high-engagement authors and merging with web-researched influencers.

Core principle: Search for authority/thought-leadership keywords, not pain-language. We want people who shape conversation in the space — conference speakers, newsletter writers, podcast hosts, and prolific LinkedIn posters.

Phase 0: Intake

Ask the user these questions:

Domain & Audience

1. What does your company/product do? What space are you in?
2. What specific domain or topic are the KOLs you want to find expert in?
3. Who is your target audience? (The people the KOLs influence)
4. Any KOLs you already know about? (LinkedIn URLs — these become the baseline)
5. Anyone to EXCLUDE? (Competitors, your own team, irrelevant voices)

Phase 1: Generate Domain Keywords

Based on intake, generate 15-25 topic/authority keywords. These are NOT pain-language — they're the terms thought leaders use when sharing expertise:

• Industry terms — "freight tech", "supply chain innovation"
• Thought leadership signals — "lessons learned in logistics", "future of dispatch"
• Conference/event terms — "supply chain summit keynote"
• Content creator signals — "newsletter freight", "podcast logistics"

Also generate:

• KOL title keywords — titles that signal thought leadership (vp, founder, analyst, editor, host)
• Vendor exclusion keywords — titles to filter out (software engineer, recruiter, saas)
• Domain relevance keywords — core industry terms for relevance scoring

Present keywords to user for approval before running.

Save config in the current working directory or wherever the user prefers:

Config JSON structure:

{
  "client_name": "example",
  "domain_keywords": ["\"freight tech\" thought leadership", "supply chain innovation"],
  "exclusion_patterns": ["hiring.*position", "we.re recruiting"],
  "kol_title_keywords": ["vp", "founder", "analyst", "editor", "host"],
  "vendor_exclude_keywords": ["software engineer", "saas", "recruiter"],
  "domain_relevance_keywords": ["freight", "logistics", "supply chain"],
  "country_filter": "",
  "max_posts_per_keyword": 50,
  "min_posts": 2,
  "min_total_engagement": 50,
  "top_n_kols": 50
}

Phase 2: Run KOL Discovery Pipeline

python3 skills/kol-discovery/scripts/kol_discovery.py \
  --config kol-discovery.json \
  --output-dir . \
  [--test] [--web-kols kol-web-kols.json] [--yes]

Flags:

• --config (required) — path to client config JSON
• --output-dir — directory for output CSV (default: current working directory)
• --test — limit to 5 keywords (validation run)
• --web-kols — path to web-researched KOL JSON (agent generates this)
• --yes — skip cost confirmation prompts
• --max-runs — override Apify run limit

What the script does:

1. Keyword search — apimaestro/linkedin-posts-search-scraper-no-cookies for each domain keyword
2. Author aggregation — Group posts by author, compute engagement metrics
3. Scoring — Composite KOL score: engagement volume (log-scaled) + consistency (post count) + quality (avg engagement) + relevance (keyword breadth) + web research bonus
4. Merge — Combine post-data KOLs with web-researched KOLs, flag overlaps
5. Export — Ranked CSV

Cost estimate: ~$0.10 per keyword. Full run with 20 keywords: ~$2-3.

Always run with --test first.

Phase 2b: Web Research (Agent-Driven)

Before or alongside the script, do web research to find known KOLs:

• Search for "top [industry] influencers on LinkedIn"
• Find conference speakers, newsletter authors, podcast hosts
• Check industry publications for frequent contributors

Save as JSON in the current working directory:

[
  {
    "name": "Jane Doe",
    "linkedin_url": "https://www.linkedin.com/in/janedoe/",
    "source": "FreightWaves conference speaker 2025",
    "notes": "Hosts weekly logistics podcast"
  }
]

Pass to script via --web-kols.

Phase 3: Review & Refine

Present results:

• Top 20 KOLs — rank, name, headline, KOL score, total engagement, top post
• Source breakdown — how many from post-data vs web-research vs both
• Keyword performance — which keywords surfaced the most KOLs

Common adjustments:

• Too many irrelevant authors — refine domain keywords, add exclusion patterns
• Missing known KOLs — add more keyword variants, expand web research
• Too few results — lower min_posts or min_total_engagement thresholds
