Free LinkedIn Lead Magnet Finder
Who asked for help in your niche this week? Every lead-magnet post on LinkedIn leaves behind a comment section full of people publicly asking for something. Find this week's posts, and see how many that is.
We read public posts from the last seven days. You see the count without creating an account.
How it works
We find this week's magnet posts
Posts in your niche that offer a free resource in exchange for a comment. We spot them by engagement shape, not by wording, so the ones hiding the ask inside an image still show up.
We count who raised their hand
Every comment on those posts is a stranger publicly asking for something on a topic you sell into. We add them up and show you the total.
You decide what to do about it
The list is yours for an email. Working it is the hard part, especially across several client accounts, and that is the job CampaignStack does.
Why comment sections are the best lead list on LinkedIn
A lead-magnet post offers something useful, usually a template or a playbook, and asks readers to comment a word to get it. The good ones collect hundreds of comments in a couple of days. Every one of those comments is a named professional publicly saying they want help with a specific topic. You did not infer that from a job title. They said it.
That is a better qualified audience than most paid lists, and it is completely public. The catch is that it belongs to whoever posted it, and it decays fast. A post that ran last Tuesday is already cold by the following week, which is why finding them has to be a habit rather than a project.
LinkedIn has made them harder to spot. Posts that spell out the ask in the text get less reach, so creators now put 'comment GUIDE to get it' inside the image and leave the text vague. Searching for the phrase stopped working. Counting engagement still does: a magnet post collects far more comments than reactions, which is the opposite of every other kind of post, and that is what this tool measures.
Sometimes the answer is that there is nothing here
Lead magnets only run where people build an audience on LinkedIn. That means marketing, sales, SEO, recruiting, and anything to do with AI tooling. We measured several other industries and found almost nothing: roofing returned four creators and a maximum of one comment, dental returned no posts at all.
If your niche comes back empty, that is a real finding rather than a broken search, and we will tell you so plainly instead of showing you a blank page. It means your buyers are not on this channel, and no tool will change that. Better to learn it in thirty seconds than after a month of outreach.
Frequently asked questions
What counts as a lead magnet post?
A post that offers a free resource and asks readers to comment to receive it. We identify them by engagement shape: magnet posts collect more comments than reactions, which almost no other kind of post does.
Do I need a LinkedIn account?
No. There is nothing to connect and nothing to paste. We would not ask a stranger for their LinkedIn account, and you should not hand one to a company you met thirty seconds ago.
Is it really free?
Yes. The number of magnet posts and the total number of people who commented on them are free with no account. The list of posts, with links, unlocks with your email.
Why can't I see who commented?
Because collecting them is the actual work, and it is what CampaignStack sells. Pulling several hundred commenters and writing to each one is a different job from finding the posts, and it is the half that gets accounts restricted.
Who is this built for?
Lead-generation agencies running outreach on client accounts. That is who CampaignStack is for: per-account daily budgets, business-hours pacing, one proxy per account, and a review queue that is on by default so a client's contact never receives a message nobody approved.
How fresh are the results?
We look at the last seven days. Magnet posts decay quickly: once a post stops being shown, the comments stop arriving, so an old one is not worth working.
Can I scan a niche that isn't mine?
Yes, any topic works. Scanning an adjacent niche is a fast way to see whether your buyers gather somewhere you had not thought to look.
Is it OK to contact people who commented?
They commented publicly on a public post about a topic, which is the same signal any social selling tool works from. It is on you to write something worth reading rather than blasting them, which is also the only thing that works.
