The story
Tomasz runs a builders merchant. His customers are contractors doing take-offs: they need a quantity of a specific material at a specific spec, and they are working out what the job costs before they quote it.
That search is a specification plus a unit — a thickness, a sheet size, a grade, a price per unit — and often a location, because materials are heavy and delivery radius decides who can even supply. His pages carried product names and a request-a-quote button.
Publishing specifications and units as text, stating the delivery area, and enabling local schema meant that the searches contractors actually run started reaching a merchant who could serve them.
