01Give categories a clear job
Start with the ways customers compare the range. Categories should organise meaningful product groups rather than create many pages for slight keyword variations. Provide useful buying information where it supports the decision, such as compatibility, sizing or the difference between product types.
Map important searches to the page that can actually answer them. A broad comparison may belong on a category or guide, while a precise model enquiry belongs on the relevant product page. Avoid making several nearly identical pages compete for the same job.
02Make product information dependable
Use accurate names, specifications, variants, availability and delivery information. Manufacturer text may be necessary for technical details, but customers also need the store’s own support, fulfilment and purchase context. Keep structured product data consistent with what is visible and with the active catalogue.
Google’s ecommerce documentation covers product and site-structure considerations. Eligibility for a search feature is not a promise that the feature will appear.
03Control filters and catalogue changes
Filters can help customers while producing a very large number of URL combinations. Decide which combinations deserve independent search pages and how the rest are linked or handled. Review pagination, canonicals and stock changes in the actual platform before applying rules.
An unavailable item needs a useful customer path. The right treatment depends on whether it is temporarily out of stock, replaced by a suitable alternative or permanently discontinued. Do not redirect every unavailable product to the homepage.
