The story
Petra supplies safety equipment and workwear to trade and industrial customers. Her buyers are not choosing; they are complying. A site specification or a regulation names a standard and they must find equipment that meets it exactly.
Her listings named models and used the word safety a great deal. The standard designations and rating classes — the literal thing buyers search — were in a compliance PDF and occasionally in a bullet nobody indexed.
Publishing standards and ratings in titles and descriptions, adding FAQ schema for compliance questions, and building standard-led collection pages made her catalog match the searches that compliance buying produces.
