# The single-keyword test

**You need:** two or more sites in one niche, and each one's idea.

## Instructions for the AI
For the keyword below, write the angle each of my sites would take. Keep the facts the same on every site. Answer in JSON: site, angle, and the one site a reader could swap it with without noticing, or null.

## Read the answer
- A site named as swappable shares its angle with another site. Fix the idea, not the article.
- Act on the site that comes back in every run. One answer from a model is noise.

## Make it yours
- Pick a hard keyword: a term whose facts cannot change, so every site has to say the same true things.
- Give it each site's whole idea: its core idea, its instinct and what its reader leaves with. On one-line ideas alone it flags far more pairs.

## How we tested it
Three fresh Claude Sonnet sessions, 2 October 2026, on our own seven sites and a real keyword (both kept private). The flagged pair changed every run: D with F, then D with G, then A with F and D with G. Site D was in all three.
