The story
Jan supplies tools, fixings and hardware to trade and DIY customers. His fixings catalog runs to thousands of variants distinguished by thread size, length, material grade and standard, and almost all of them are named something like "Hex Bolt (Pack of 50)".
His buyers search exact identifiers: a DIN standard, a metric thread and length, a material grade, a battery platform for a power tool. These are the highest-intent searches on the internet — the person already knows the exact part — and his pages matched none of them.
Putting the full identifier into titles and descriptions, adding compatibility language for tool platforms, and building specification-led collections converted a catalog of anonymous packs into thousands of exact-match landing pages.
