LinkedIn Comment Scraper

Pull every commenter from a LinkedIn post into a clean, deduped list. Phase 1 of the comment-to-outreach pipeline, but you can run it standalone if you only need the list (e.g. as input to a different downstream tool).

When to use

• "Scrape commenters from this LinkedIn post: ".
• "Pull a list of who commented on this post".
• You want a clean, deduped commenter list for any downstream use - not necessarily cold outreach.

When NOT to use

• You want to react to a post (not comment) - use linkedin-reaction-scraper.
• You want the full end-to-end pipeline through to Instantly - use linkedin-comment-to-outreach.

Connections I need

• Apify (scraping) - Required. I use the harvestapi/linkedin-post-comments actor.

If Apify isn't connected I stop and ask you to connect it from the Integrations tab.

Information I need

• The LinkedIn post URL - Required. If missing I ask: "Which LinkedIn post should I scrape?"
• A target item count - Optional. Defaults to defaultMaxItems from your outbound context (500). Override per call if you only want a quick test pull.

Steps

1. Validate URL. Confirm the URL is a LinkedIn post (linkedin.com/posts/... or linkedin.com/feed/update/...). Reject profile URLs, article URLs, company URLs. If the input is a short link or a redirect, follow it once to resolve the canonical post URL before scraping.

2. Test pull. First call to the actor with maxItems: 20 to confirm the post is reachable and the actor returns the expected shape. If the test pull returns 0 items, stop and surface why (post deleted, comments disabled, geo-blocked, actor cold-start).

3. Full pull. Call the actor with maxItems: {target} (default 500). Wait for the run to finish. Apify typically takes 2-5 minutes for the full pull.

4. Dedupe. Group raw items by profileUrl. For duplicates within one scrape (same person commented multiple times), keep the row with the longest comment text. Drop rows where profileUrl is null or where fullName is null - these are scrape misses, not real leads.
