Turn Your LinkedIn Posts into Automated Lead Magnets

If you’re already sharing valuable content on LinkedIn (ebooks, checklists, guides, or videos) you might have noticed a powerful trend:
people commenting to get access.

Those commenters are warm leads. They’ve engaged with your post, shown intent, and essentially asked to be contacted.

The challenge? Doing it manually. Accepting new connection requests, checking every comment, and sending out the resource by hand quickly becomes slow, inconsistent, and messy.

This Playbook shows you how to automate the entire process in just three steps, turning your best-performing LinkedIn content into a repeatable, conversion-driven lead magnet workflow.

Step 1: Automatically Accept Connection Requests

When your post goes viral or gets solid engagement, you might receive dozens (maybe even hundreds) of new connection requests.
Instead of accepting them manually, let automation do it for you.

In PhantomBuster:

1. Go to Solutions → LinkedIn → LinkedIn Auto Invitation Accepter.
2. Click Use Now.
3. Set the behavior to accept up to 10 invitations per launch.
4. Under Launch Settings, select Repeatedly → Once per working hour (9 AM–5 PM).

This means that every hour, PhantomBuster will check for new connection requests and automatically accept them, ensuring that all new leads from your post are ready to receive your next message.

💡 Tip: You can fine-tune the exact minute the automation runs (for example, at the first minute of every hour) to align it with your next step.

Step 2: Extract Commenters from Your Lead Magnet Post

Before setting up the automation, make sure your LinkedIn post is ready.
It should clearly invite people to comment with a specific keyword to receive your resource.

Example:

“Comment LEADS below, and I’ll send you a video and checklist on how to automate your lead generation on LinkedIn!”

Once your post is live and engagement starts coming in:

1. Copy the URL of your LinkedIn post.
2. Go to PhantomBuster → Solutions → LinkedIn Post Commenters Export.
3. Paste your post URL.
4. Switch to Advanced Settings and activate Watcher Mode.

Watcher Mode continuously monitors your post and captures new commenters in real time even hours or days later.

For the Launch Settings:

• Choose Repeatedly → Once per working hour.
• Set the launch time around 10 minutes after your Auto-Invitation Acceptor runs.

This allows enough time for PhantomBuster to accept connection requests before extracting the new commenters.

Step 3: Send Your Resource Automatically to Qualified Commenters

Once the comments are extracted, you’ll have a full list of people who interacted with your post.
You can manually review the comments in a Google Spreadsheet to make sure the keyword matches your criteria.

1. Download the commenters’ list from PhantomBuster.
2. Import it into a Google Sheet.
3. Filter and remove users who didn’t comment with the right keyword.
4. Copy the spreadsheet URL.

Now, in PhantomBuster:

• Open the LinkedIn Message Sender Phantom.
• Use your Google Sheet as the input.

• Write your outreach message, for example:

  “Hi {{firstName}}, thanks for commenting on my post! Here’s the resource I mentioned: [Insert link]. Hope you find it useful!”

• Under Behavior, set a safe limit for example, 10 messages per hour, up to 80 per day.
• Launch the Phantom.

From now on, each new commenter who matches your criteria will automatically receive your resource via LinkedIn message.

Why This Workflow Works

This playbook takes a high-performing LinkedIn post, something that’s already attracting interest, and turns it into a fully automated lead generation funnel.

It works because:

• You’re engaging people who already showed intent.
• You respond instantly and at scale.
• You stay fully compliant with LinkedIn limits and natural interaction pacing.

Instead of manually tracking comments and sending resources, you can focus on creating more valuable content while PhantomBuster handles the engagement follow-up.

Workflow Recap

1. LinkedIn Auto-Invitation Accepter: Automatically approve all incoming connection requests.
2. LinkedIn Post Commenters Export: Continuously extract new commenters using Watcher Mode.
3. LinkedIn Message Sender: Automatically send your resource to every qualified commenter.

Together, these three automations create a simple but powerful system that turns every engaged post into a stream of qualified leads — all while you focus on growing your brand.
