E-commerce SEO
In one line
E-commerce SEO is the specialised practice of optimising shops — product pages, categories, faceted navigation, stock changes — where the structural issues are very different from a content site.
Going deeper
E-commerce SEO has a different shape from content-site SEO. Catalogues run into the tens of thousands of SKUs, faceted filters explode the URL space, and inventory changes mean products vanish and reappear. So the recurring questions look like category architecture, faceted indexing policy, out-of-stock and discontinued handling, and Product structured data.
Product schema — price, availability, rating — is arguably the highest-value structured data in commerce. Rich results showing price and stars move CTR directly, and the same fields are increasingly being lifted straight into AI answers.
Discontinued and out-of-stock handling is the part most teams forget. Permanent discontinuations should 410 or 301 to a relevant category; temporary stockouts are usually best handled by keeping the page live with an 'Out of Stock' state plus relevant alternatives.
