# Technical SEO Checklist ## Crawl and indexation - Confirm indexable money pages and noindex low-value or duplicate pages. - Define robots policy for search, cart, account, internal filters, and thin utility pages. - Ensure XML sitemaps exist for key page groups and exclude noindex URLs. ## Canonicalization and duplication - Define canonicals for categories, filtered states, sorting states, pagination, and product variants. - Prevent duplicate content across collection pages, brand pages, and promotional landings. ## Rendering and architecture - Ensure key content is available in server-rendered or reliably rendered HTML. - Confirm crawlers can see titles, headings, main content, structured data, and internal links. ## Performance and Core Web Vitals - Optimize LCP, INP, and CLS on category and product pages. - Control image size, font loading, script weight, and third-party bloat. - Avoid layout shifts from banners, lazy media, and client-only widgets. ## Media and assets - Use descriptive image filenames where practical. - Provide alt text with functional accuracy, not keyword stuffing. - Generate responsive image variants and preload only what is truly critical. ## Navigation and page discovery - Ensure deep categories and products are reachable through internal links. - Use breadcrumbs and clear taxonomy-based navigation. ## International and local SEO when relevant - Use hreflang carefully only when multiple locales truly exist. - Align locale routing, canonicals, translated metadata, and sitemap structure.
