• /catalog/?category=reagents&priceMin=30&priceMax=9999 : catalog web app, canonical /, noindex

  • /reagents/someReagent : some product page, product page should link to /reagents

  • /reagents/(productSlug)

  • /reagents/ : SEO catalog, 1 page, here we should show near 50 links to product page

  • /reagents/2 : SEO catalog, 2 page

  • /(category)/(pageNum) : SEO catalog, 3 page

Problem: what should we show at /(category) page. We can show some stub, and then list (pageNum)
