The four-pillar magnet map
One magnet, one job
A magnet that converts is still a failure if it converts the wrong person at the wrong moment. The format question, finish a job versus teach a topic, tells you how good a magnet can be. The funnel question tells you whether it belongs where you are putting it at all. The discipline is simple to state and easy to violate: one magnet, one funnel job. Mismatched magnets leak, because they capture people the next stage cannot do anything with.
Think of the funnel as four jobs, each needing its own kind of bait. Demand makes a stranger care. Activation turns interest into a named lead. Pipeline pre-qualifies that lead into a real opportunity. Revenue arms an existing buyer to win the deal internally. A magnet built for one of these jobs will underperform or actively mislead if you deploy it for another.
The four pillars, and the magnet each needs
Demand is the job of making someone who has never heard of you stop and care. The magnet here is a teardown or a benchmark, something that shows a stranger a truth about their own situation they did not know. A breakdown of how the best players in their category structure something, or a benchmark that lets them place themselves against peers, creates the itch that everything downstream depends on. The job is not capture yet, it is to make a stranger lean in.
Activation is the job of turning that interest into a named, contactable lead. This is where the calculator and the assessment live, because they trade a personalised result for an email and the trade feels fair. The prospect gives you their address to get their number or their score, and both sides come out ahead. This is the pillar most founders mean when they say "lead magnet", and it is the one where finishing a job pays off hardest.
Pipeline is the job of pre-qualifying a lead into a genuine opportunity. The magnet here is a scoping tool or an audit, something that requires the prospect to reveal enough about their situation that, by the time they reach you, the qualification is already half done. An audit of their actual asset is the strongest play, because it doubles as the opening of the sales conversation. The job is to separate the serious from the curious before a human spends time on them.
Revenue is the job of helping an existing buyer sell you internally. The magnet here is an ROI model, a tool the buyer takes into their own organisation to make the business case to the people who control the budget. You are not winning the buyer here, you already have them. You are arming them to win the colleagues whose sign-off they need.
Where the leaks happen
The failures are predictable once you have the map. A comprehensive guide deployed as an activation magnet leaks because it teaches a topic where a job needed finishing. A heavy audit thrown at cold demand traffic leaks because you asked a stranger to reveal their situation before they had any reason to care. An ROI model shown to a first-time visitor leaks because it arms a decision nobody has decided to make yet.
Before you build, name the pillar. Then choose the highest finish-a-job format that fits that pillar, and only that pillar. The map and the format hierarchy work together: the map tells you which job, the hierarchy tells you how well to do it. Get both right and the magnet stops leaking.
