What did you
forget?
Five questions. You'll get the one gap that's actually broken - and the three moves to make, in order.

The five gaps, in full
Post-launch silence always has a cause, and it's nearly always one of these five. The reason this matters: each one has a completely different first move, and the wrong move can cost you a quarter.
1 · Visibility - nobody arrives
Under about 100 visits a month you cannot diagnose anything else, because there isn't enough data for any conclusion to be real. Everything you'd "test" is noise. The job is getting found: one search surface, one query you can genuinely own, and a check that machines can see you at all - an alarming number of AI-built sites render as an empty shell to a crawler and are invisible from birth. In 2026 this also means AI answers: if someone asks ChatGPT for a tool like yours and gets the same five names every time, you are not in the consideration set that matters most.
2 · Positioning - they arrive and bounce
Traffic exists, and it leaves in under fifteen seconds. That is not a traffic problem and no amount of extra traffic fixes it - you'd just be buying more people to confuse. Someone must understand what this is, who it's for, and what it replaces, within about four seconds of landing. The test that hurts: show your page to five people who match your buyer for five seconds, take it away, and ask what it does and who for. If they can't answer, nothing downstream matters.
3 · Funnel - they get it and still don't convert
They understand it, they sign up, and then they evaporate - or they use it happily and never pay. There's a specific step where people fall out, and the reason it stays broken for months is that nobody instruments it. This is where "users who'd cry if it disappeared but won't pay" lives, and that's a pricing and packaging problem wearing a growth costume.
4 · Measurement - you can't tell which of the above is true
The most common gap, and the most expensive, because it makes every other decision a coin flip. If you can't say what your activation event is, or what share of visitors reach it, you are guessing. One founder discovered three years after launch that his day-one retention was 4.2% against a 40% benchmark; the data was always there, nobody had defined the number. Fix this first when it applies - everything else gets cheaper afterwards.
5 · Loops - you convert but nothing compounds
Real users, real revenue, flat growth. Every new customer costs the same as the last one because nothing about having customers makes the next one easier to get. The fix isn't more channels, it's finding the one loop your product can actually run - content that earns links, users who invite others, output that gets shared, data that improves the thing - and then measuring its cycle time like a real system.
These stack. Fixing your funnel while you have no traffic produces nothing measurable. Buying traffic while your positioning is broken burns money at scale. Building loops before you convert compounds zero. The diagnostic exists because almost everyone works on gap three while their actual problem is gap one - and because the honest answer to "what should I do next" is usually "not the thing you were about to do."
