Two lead magnets, side by side.

After 600+ lead magnets across more than a hundred high-ticket industries, the difference between magnets that print booked calls and ones that just print downloads comes down to what they were built to do. Most are built to pull a crowd. The good ones are built to pull a buyer and let the crowd walk away on its own.

❌ Crowd magnet
  • Downloads climb fast. You feel good, until you open your calendar.
  • Wrong industry, wrong size, someone three years from being ready.
  • A week of polite calls with people who were never going to buy.
✓ Buyer magnet
  • Fewer downloads. Quieter numbers.
  • Almost everyone is your industry, your size, with the problem you solve.
  • A week of calls that actually go somewhere.
A great lead magnet is a filter, not just bait. It pulls the right buyer in and lets the wrong-fit person opt themselves out before they ever hit your calendar.
01
Specificity

Make the wrong-fit buyer opt themselves out.

The rule underneath everything: the more specific your lead magnet, the harder it works as a filter.

❌ Too broad
  • Free marketing tips
  • Get more clients
✓ Sharply specific
  • How to structure retainer pricing for a multi-location services business doing $2M+
  • Restructure your sales process when your close rate drops at deals over $20K
The fear nobody talks about
Most people are scared to get this specific. They think a narrower magnet means fewer leads, and fewer feels like losing. But you don't want more leads, you want fewer, better ones. 500 downloads with three real buyers loses to 60 downloads where 20 can pay you. A crowd is not a pipeline.
02
Topic

Let the topic do the first round of filtering.

The topic you choose filters before a single word of your copy gets read. Someone typing the generic version of a problem and someone typing the expensive version of that same problem are two different people with two different bank accounts.

❌ Hobbyist search
  • How to get more clients
✓ Buyer search
  • How to restructure my sales process when my close rate drops at deals over $20k

Pick the topic only your real buyer would ever search for. The specific, expensive, high-stakes version. The topic becomes a tripwire: buyers walk right into it because it names their reality. Hobbyists never find it because they're not searching at that altitude.

03
The Qualifier

One question sorts buyers from browsers.

Once someone opts in, you get one question. Use it wrong and you scare off good buyers. Use it right and you sort everyone in two seconds.

Ask about intent, not income. A real buyer answers yes without a second thought, it's already on their mind. A tire-kicker hesitates, because it isn't.

Capture exactly these fields. Nothing more.

  1. 1
    Name
    So you can address them personally in every follow-up.
  2. 2
    Email
    So you can actually reach them with your sequence.
  3. 3
    Phone
    So you have a direct line when the moment is right.
  4. 4
    The one intent question
    So you know who is worth reaching. Nothing more.
04
The Loop

Teach the platform who to bring you next.

That one question doesn't just sort leads. If you're running ads, it trains the platform, and the cost math turns in your favor.

01
Collect yes/no
On every opt-in
02
Feed signals back
To the ad platform
03
Platform learns
What a real buyer looks like
04
More yes buyers
Cheaper, every week
The counterintuitive result

Quality up. Cost down. Same motion.

Most people assume quality and cost pull against each other: better leads, higher price. Not here. One signal solves both, because you've stopped paying to put your magnet in front of the "no" crowd.

Run the filter on your current lead magnet, six boxes, ten minutes.

  1. 1
    Title
    Could a tire-kicker read it and instantly feel it's not for them? If no, it's too broad.
  2. 2
    Topic
    Does it name the specific, expensive version of the problem, not the beginner version?
  3. 3
    Hook
    Read your first line as a tire-kicker. A good hook makes the wrong person scroll past and the right person stop.
  4. 4
    Qualifier
    Exactly one question, about intent, not revenue or title?
  5. 5
    Capture fields
    Name, email, phone, plus that one question. Nothing more.
  6. 6
    Feedback loop
    If you run ads, are you feeding yes/no back so the platform learns who to find?

The filter in 60 seconds.

01
Specific
Sharp enough that only a real buyer wants it.
02
Right topic
What your buyer searches; what the hobbyist never will.
03
One question
Intent, never income. Plus name, email, phone.
04
Feed the loop
Quality up, cost down, same motion.
