Seven positioning questions
Monopoly or competition, the secret, 10x or incremental, definite or indefinite optimism, distribution, vertical or horizontal progress, and durability.
Get the argument
The verdict, then each finding framed as an argument: what your page implies, why that is the wrong claim to be making, and what to claim instead.
Read enough landing pages in one category and they converge. Each one is faster, simpler, more collaborative than the last, and each one is describing the same market from a slightly different seat in it. That is what competing looks like from the outside, and it is a bad position to be arguing from, because a reader comparing five pages that make the same claim will pick on price.
The alternative is not louder copy. It is a page that defines a category it is the only member of, which requires believing something the rest of the category does not. That belief is the thing this review looks for, and its absence is the most common finding.
Thirty percent faster is a real improvement and almost nobody switches for it. Switching costs time, risk and political capital, and a margin does not cover them. An order of magnitude does. When this review objects to your strongest claim, it is usually not because the claim is false — it is because it is too small to act on.
Pages describe the product exhaustively and say nothing about how anyone is supposed to find it. That silence usually reflects a real gap rather than an editorial choice, and it is the more common reason good companies fail than the product ever is.
No. It is a review lens distilled from his published writing — Zero to One, the Wall Street Journal essay, and the Stanford lecture notes the book came from. It applies the arguments in those to your page. It never writes as him, never claims to know what he would say, and never invents quotations.
