Body copy
One check, stated three ways: what we measure, what would make it wrong, and how to confirm it yourself.
What this measures
How much visible text the page carries and whether it states who the product is for and what it does.
Where this check can be wrong
A genuinely excellent one-screen product page can be short and still convert. This measures volume and structure, not writing quality.
Verify it without taking our word for it
Read your own page as a stranger: could someone say what you sell and to whom, in fifteen seconds, without scrolling?
