Ecommerce SEO depends heavily on category structure, product discoverability and duplicate-content control. Search engines should be able to reach important products through normal navigation rather than relying only on search forms.
What to consider
Write category descriptions that help shoppers understand the selection and avoid copying manufacturer descriptions across large numbers of products. Structured data can help communicate product details when it matches visible information.
Manage filters, pagination, out-of-stock products and discontinued URLs carefully so the site does not create thousands of low-value indexable pages.
