description

Scrape LinkedIn post commenters and export Lemlist-ready CSVs, with optional ICP filtering. Use this skill when the user wants to scrape engagement from a LinkedIn post, extract commenters, build a lead list from LinkedIn post interactions, generate a CSV for Lemlist import, or filter scraped contacts against an Ideal Customer Profile. Triggers on "scrape LinkedIn post", "get commenters", "LinkedIn engagement", "post engagers", "Lemlist CSV", "who commented on this post", "ICP filter", "ideal customer profile", or "filter leads".

LinkedIn Engagement Scraper

Scrape everyone who engaged with a LinkedIn post and produce two Lemlist-ready outputs:

1. All engagers — everyone who commented, ready for Lemlist import
2. ICP matches — only the people who match your Ideal Customer Profile

Prerequisites

Requirement	Details
PHANTOMBUSTER_API_KEY	Settings → API
PHANTOMBUSTER_AGENT_ID	From phantom URL: phantombuster.com/phantoms/<ID>/...
Python packages	pip install requests python-dotenv

Set the env vars in a .env file in the working directory. See references/phantombuster-setup.md for full PhantomBuster setup instructions.

Step 1: Scrape Engagers

python <skill-path>/scripts/scrape_engagers.py "<linkedin_post_url>"

This launches PhantomBuster, waits for results, and outputs:

File	Purpose
output/all_engagers_YYYY-MM-DD_HHMMSS.csv	All contacts, Lemlist-ready. Import directly.
output/engagers.json	Full contact data with seniority tagging. Feed to Step 2.

Step 2: Filter by ICP (Optional)

python <skill-path>/scripts/filter_icp.py output/engagers.json

The script prompts you to define your ICP interactively:

--- Define your Ideal Customer Profile ---

Segment 1:
  Industries (comma-separated, or blank for any): saas, fintech
  Target titles/keywords (comma-separated, or blank for any): vp, head of, director
  Minimum seniority [c_suite / vp / director / manager / senior_ic / any]: director
  Company name keywords (comma-separated, or blank for any):

  Add another segment? (y/n): n

Or reuse a saved ICP:

python <skill-path>/scripts/filter_icp.py output/engagers.json --icp output/icp_criteria.json

Output:

File	Purpose
output/icp_matches_YYYY-MM-DD_HHMMSS.csv	Strong + likely ICP matches, Lemlist-ready
output/icp_criteria.json	Your saved ICP (reuse on future scrapes)

ICP Matching Logic

Each contact is scored against your ICP segments on four dimensions:

Dimension	Source	What it checks
Title keywords	LinkedIn headline	Does their title contain your target keywords?
Company keywords	LinkedIn headline	Does their company match your targets?
Seniority	Parsed from title	Are they at or above your minimum seniority level?
Industry	LinkedIn headline	Does their company/headline match your target industries?

Fit ratings:

• Strong fit — Matches all active criteria
• Likely fit — Matches all but one criterion
• Weak fit — Partial match
• No fit — Doesn't match

The ICP CSV includes strong + likely fits. Weak fits are output as a fallback if no strong/likely matches exist.

Seniority Levels

Parsed automatically from job titles:

Level	Example titles
c_suite	CEO, CTO, Founder, Chief __ Officer
vp	VP, SVP, Head of, Partner
director	Director, Senior Director, Managing Director
manager	Manager, Senior Manager, Product Manager
senior_ic	Principal, Staff, Lead, Architect
individual_contributor	Everything else

See references/icp-parsing-guide.md for detailed parsing rules.

Lemlist CSV Columns

Both output CSVs use the same Lemlist-compatible format:

Column	Description
email	Blank — Lemlist enriches from LinkedIn URL on import
firstName	First name
lastName	Last name
companyName	Company (extracted from LinkedIn headline)
linkedinUrl	LinkedIn profile URL
jobTitle	Job title (extracted from LinkedIn headline)
icebreaker	Comment text — use {{icebreaker}} in Lemlist templates
icpFit	(ICP CSV only) strong_fit or likely_fit

Importing into Lemlist

1. Open Lemlist → your campaign → Import
2. Upload the CSV (either all_engagers or icp_matches)
3. Lemlist auto-enriches emails from the LinkedIn URLs
4. Use {{icebreaker}} in your email template for personalization

Troubleshooting

Issue	Fix
412 Precondition Failed on launch	Enable auto-launch in PhantomBuster phantom settings
403 or auth errors	Check PHANTOMBUSTER_API_KEY in .env
0 contacts returned	Post has no comments, or PhantomBuster session cookie expired
Missing company/title	Person's headline doesn't follow "Title at Company" format
0 ICP matches	Broaden criteria — try fewer keywords or lower seniority minimum
