# Query-conditional rewrites are a targeted experiment

> Rewriting descriptions to match likely queries produces concentrated, not universal, gains, so treat it as a measured experiment on candidate SKUs rather than a blanket promise.

## Per-platform status

Undocumented platforms show "unknown" - honest unknowns, never invented.

## How to act on this

Rewrite a small batch of candidate SKUs (same facts, no new claims), measure win rate per engine before and after, and serve identical copy to bots and humans.
