LinkedIn Post Research

Search LinkedIn for posts matching keywords via Apify. Returns posts sorted by engagement or date, with author info, full text, reaction counts, and direct URLs.

No LinkedIn cookies. No login. Just keywords in, posts out.

When to Auto-Load

Load this skill when:

• User says "search LinkedIn posts", "what are people saying about X on LinkedIn", "find LinkedIn content about"
• User wants to find high-engagement posts on a topic
• User wants to identify who's posting about a specific topic (thought leader discovery)
• User wants to find posts to extract commenters from (warm lead pipeline)

Prerequisites

Apify API Token

Required for searching LinkedIn posts. Set in .env:

APIFY_API_TOKEN=your_token_here

No LinkedIn cookies, login, or session tokens needed. That's the only setup.

How It Works

1. Takes one or more keywords
2. Calls the apimaestro/linkedin-posts-search-scraper-no-cookies Apify actor
3. Returns posts with author, text, engagement metrics, date, and URL
4. Deduplicates across keywords by activity_id
5. Sorts by engagement (total reactions) descending, or by date

Quick Start

bash
# Single keyword search
python3 skills/capabilities/linkedin-post-research/scripts/search_posts.py \
