A model code that fits two categories used to get two nearly identical pages. Each of the 96 model codes now has a single canonical URL under its primary category, showing every catalog photo of that code and every category it is listed in, and the 30 former duplicate addresses redirect to it.
The sitemap is now an index over child sitemaps — pages, products, countries and one per language — and every URL carries a real lastmod date derived from the content that page renders, not the build date. An HTML site map at /sitemap/ lists the same routes for readers.
The person who answers RFQs now has a page. /company/steven/ carries the export manager's experience, the languages an inquiry can arrive in, and what he handles; every buyer guide byline, author box and topic reviewer credit links to it, and the Person node in the structured data resolves to it.
