Product page SEO optimization checklist, in order of impact. (1) Write unique product copy — at minimum 200 words of original description, ideally 500+ for higher-AOV items. Manufacturer-supplied copy that appears on dozens of competitor sites gets near-zero ranking traction. (2) Implement complete schema markup — Product, Offer (with priceCurrency CAD for Canadian stores), and AggregateRating where genuine reviews exist. (3) Collect and display real customer reviews — both for conversion and for ranking signal. (4) Optimize product images — descriptive filenames (red-leather-wallet-mens.webp not IMG_4823.jpg), specific alt text, multiple angles, served in WebP/AVIF, properly sized for mobile. (5) Internal link from related products, category pages, and any relevant blog content. (6) Handle URL parameters cleanly — ?color=red should canonicalize to the parent product or be properly indexed if it represents a distinct buyable variant. (7) Use breadcrumbs with BreadcrumbList schema. (8) Maintain price, availability, and review freshness — stale data triggers indexing penalties for Shopping rich results.
