LinkedIn Post Commenter and Liker Scraper

PhantomBuster’s LinkedIn Post Commenter and Liker Scraper Automation extracts profiles of users who comment on or like LinkedIn posts from your chosen sources. This tutorial shows you how to set up, launch, and review results with this Phantom.

• Technical requirements: Connected LinkedIn account (via extension or cookie) and one or more valid LinkedIn source URLs; optional HubSpot account for auto-sync.

• Operational limits: Processes up to 8 posts per day and monitors up to 50 posts at once. Leads are stored hourly (up to 50 per hour).

• Scheduling: This workflow runs on a fixed schedule once daily; frequency and timing cannot be customized.

• Free plan limitations: CSV exports include only the first 10 rows; dynamic CSV/JSON downloads are unavailable.

• Slot usage: 1 slot. Typical end-to-end time for 10–20 recent engagers is about 5–10 minutes.

1. Choose your LinkedIn source(s): Add one or more LinkedIn URLs as input: a company page, a profile page, a single post, or a post search results page.

2. Connect your LinkedIn account: Install the PhantomBuster browser extension and connect your LinkedIn session in one click. If you’re not on Chrome or Firefox, copy your LinkedIn session cookie manually and paste it in the setup.

   Keep your browser updated. Outdated Chrome or Firefox versions can cause rapid session cookie expiration and frequent disconnections.

3. Select what to extract: Choose to extract Commenters, Likers (reactions), or both. Optionally, enable HubSpot sync or limit extraction to posts published on or after a specific date in the advanced settings.

   Commenters and likers are extracted separately, so the same person may appear in two rows. Additionally, only comments visible under LinkedIn's default "Most relevant" view are guaranteed to be scraped.

4. Adjust advanced settings (optional): If needed, tweak advanced options like execution limits, retries, notifications, proxies, webhooks, and file management. Defaults are recommended unless a guide instructs otherwise.

5. Launch the workflow: Toggle the ON/OFF switch to start. The workflow runs automatically on a fixed daily schedule, monitoring your sources and extracting engagement from the most active posts.

   Avoid editing inputs after the workflow is ON; create a new workflow for new inputs to prevent errors. If issues arise, check the Logs tab, as detailed errors may not appear on the Dashboard.

6. Review results and track progress: View profiles and engagement types in the Leads tab, and see key metrics in the Report tab. The next step in the Workflow sequence appears in the Workflow Dashboard, and all data is saved to your LinkedIn Leads database.
