What Extract LinkedIn Post Commenters does

Extract LinkedIn Post Commenters returns every LinkedIn user who commented on a given post as a structured list of profiles. You get names, headlines, profile URLs, and the comment each person left — a ready-made audience that engaged deeply enough to type something.

The action runs on the LinkedIn level and is a core primitive for lead generation from organic content, yours or anyone else's.

How it works

You pass a LinkedIn post URL, Edges reads the comment thread through your authenticated LinkedIn session, and it paginates through commenters until the thread is exhausted. Results come back as JSON rows, one per commenter, with the comment text attached.

Runs execute on Edges infrastructure with safe rate pacing. Viral posts with thousands of comments should run async so pagination completes cleanly.

When to use Extract LinkedIn Post Commenters

Use Extract LinkedIn Post Commenters when a post — yours, a competitor's, or a category influencer's — has attracted comments from people who look like your ICP. Commenters are the highest-intent slice of an audience, and this action turns that slice into a workable list. It maps to the LinkedIn search API use case.

The classic play: run Extract LinkedIn Post Commenters on a competitor's feature announcement, filter commenters by title and company, and reach out to the ones saying "we wish our vendor had this."

Use cases

  • Lead generation from your own posts. Convert engagement on your thought-leadership content into a pipelineable list.
  • Competitor displacement. Extract commenters on competitor launch posts, filter for your ICP, and run referenced outreach.
  • Event recruiting. Invite commenters from a relevant category post to your next webinar.
  • Champion mapping. Find commenters at target accounts who publicly engage with your category — route to the AE.
  • Content loop. Analyse which commenter segments engage with which topics to inform future content.

Best practices

  • Score comment quality. A "great post!" is weaker signal than a thoughtful reply. Use commentText length and content to weight leads.
  • Chain enrichment. Pair Extract LinkedIn Post Commenters with Extract LinkedIn Profile before you push to CRM so rows arrive hydrated.
  • Dedupe on `publicProfileUrl`. The same commenter can appear across multiple posts in a series; use profile URL as your key.
  • Run async for viral posts. Posts with thousands of comments should run async to stay within LinkedIn's request guardrails.

Common questions

How many commenters can I extract per run?

Edges paginates the full comment thread. Very large threads should be processed async so the job is not bound to a single HTTP request.

Does Extract LinkedIn Post Commenters use my LinkedIn account or a shared pool?

Your LinkedIn account. The comment thread is read through your authenticated LinkedIn session on Edges, matching your browser view.

Can I chain Extract LinkedIn Post Commenters with other Edges actions?

Yes. A standard flow is Extract LinkedIn Post Commenters into Extract Linkedin User Contact Info for email enrichment, then into Message LinkedIn Profile for a contextual first touch.
