Faceted navigation
Filter and sort controls on listing pages that can generate a combinatorial explosion of crawlable URLs from a small product set.
Search optimisation for online retail, dominated by catalogue scale, faceted URL control, product data accuracy and the interaction between organic results and shopping surfaces.
The distinguishing problems are structural rather than editorial: hundreds of thousands of URLs generated by facets and variants, products that appear and disappear, and the need for feed data to agree with on-page markup. Category pages usually carry more commercial value than individual products, and Google's own e-commerce documentation covers pagination, faceted navigation, product markup and out-of-stock handling. Merchant Center and free product listings sit alongside classic organic work.
