The One Rule That Fixes Almost Any Landing Page

Why Breadth Kills Conversion

A landing page that tries to appeal to everyone reads like it was written for no one. The language becomes vague because there's no specific person to be specific about. The headline becomes aspirational because there's no concrete problem to address. The CTA becomes generic because there's no clear next step for any particular type of user.

Every softening decision — every time you replace “for solo founders who need their first ten customers” with “for businesses of all sizes” — widens the theoretical audience and weakens the actual conversion. The people you were trying not to exclude don't convert. The people you were originally writing for don't feel spoken to anymore.

Applying the One-Person Rule

Write your landing page for the person who would be most upset if your product disappeared tomorrow. Use their job title, their specific problem, their exact language. Make the headline about their situation. Write the copy assuming they're reading every word and checking whether it's actually about them.

When the right person reads the page and feels like it was written specifically for them, conversion is easy. Everyone else — the people who weren't your target anyway — will self-select out, which is exactly what you want.

The Compounding Effect of Specificity

Specific pages convert better. They also rank better, because search queries are specific. They get cited more by AI engines, because the content matches the exact language of the query. The one-person rule isn't just a conversion optimization — it compounds across every channel.
