The story
Sanjay runs an independent electronics retailer with several thousand SKUs. He sells exactly the same products as every other retailer, with exactly the same manufacturer descriptions, at broadly the same prices. On paper there is nothing to differentiate.
What his customers actually search is comparative and practical: how two models differ on battery life, what the warranty covers, whether an accessory is compatible, whether a refurbished unit is worth it. His pages carried the manufacturer blurb and answered none of it.
Rewriting the copy to answer comparison and compatibility questions, publishing warranty and returns answers as FAQ schema, and describing every image gave the same products a reason to rank on his site rather than everyone else's.
