LinkedIn Auto Commenter

PhantomBuster’s LinkedIn Auto Commenter Automation lets you automatically post comments on LinkedIn posts from your personal profile. This tutorial covers the setup process and key usage steps to get started quickly.

• Safety limits: Maximum 80 comments per day. For safety, limit to 10 comments per launch and spread activity across multiple launches during working hours.

• Prerequisites: Works only from a personal LinkedIn profile; company pages are not supported.

• Content constraints: Emojis are not supported. The Automation only posts new top-level comments; replying to existing comments is not supported.

• Free plan limitations: CSV upload input is not supported. CSV exports include only the first 10 rows, and direct download links or JSON exports are not available.

• Resources: Estimated execution time is about 20 seconds per comment; uses 1 slot.

1. Connect your LinkedIn account: Install the PhantomBuster browser extension and link your LinkedIn session in one click. If you’re not using Chrome or Firefox, add your LinkedIn session cookie manually.

   Keep your browser up to date; outdated versions can cause your LinkedIn session to expire quickly.

2. Provide post URLs and comments: Choose an input method: use a Google Sheet (post URLs in column A, comments in column B), upload a CSV (paid plans only), or chain data from 'My Phantoms' with both a post URL and comment field.

   Google Sheets must be shared with "Anyone with the link." Chaining from "My Phantoms" requires both a post URL and a comment field in the previous Phantom's output.

3. Configure comment behavior: Set the number of comments per launch (default 10) to mimic natural activity. Optionally enable "Post random comments" to rotate comments across posts.

   When "Post random comments" is enabled, comments may be reused across multiple posts and launches.

4. Adjust result file settings (optional): Optionally rename the results file and specify which fields to keep for a custom output CSV.

   If you rename the results file between launches, a new results file is created and processing restarts from the beginning.

5. Select launch frequency: Choose to launch manually, schedule one-time or repeated runs, trigger after another Phantom, or set advanced schedules.

6. Configure advanced settings (optional): Leave defaults unless needed. Adjust execution limits, retries, notifications, proxies, webhooks, and file management as required.

7. Launch and review results: Click Launch. Review commented posts and download results as CSV or JSON from the Results tab; track activity in the Activity tab.
