Technical SEO for e-commerce sites is fundamentally different from blog or service-site SEO. You are dealing with thousands of product pages, faceted navigation nightmares, duplicate content from variations, and page speed challenges from heavy imagery. Here is the complete checklist we use when auditing e-commerce sites.
Core Web Vitals
Google’s page experience signals remain a ranking factor, and e-commerce sites are particularly vulnerable to poor scores. Target: LCP under 2.5 seconds, FID under 100ms, CLS under 0.1. The biggest wins for e-commerce: lazy load product images, use next-gen image formats (WebP/AVIF), implement critical CSS inlining, and defer non-essential JavaScript.
Crawl Budget Optimization
For stores with 10,000+ products, crawl budget is a real concern. Key actions: block faceted navigation URLs in robots.txt (or use canonical tags), implement pagination with rel=next/prev, ensure your XML sitemap only includes indexable URLs, and monitor crawl stats in Google Search Console weekly.
Structured Data
Every product page should have Product schema with: name, description, image, price, priceCurrency, availability, brand, review (aggregate rating), and SKU. This enables rich results including price, availability, and star ratings directly in search results. We have seen click-through rates increase 20-35% after implementing comprehensive product schema.
Internal Linking
Build category-to-product and product-to-product internal links aggressively. Breadcrumb navigation, related products sections, and “customers also bought” blocks all serve dual purposes: better user experience and stronger internal link equity distribution. Every product page should be reachable within 3 clicks from the homepage.
Content Strategy for Product Pages
Thin product pages (just a title, image, and price) will not rank. Each product page needs: a unique description of at least 200 words, specification tables, FAQ sections targeting long-tail queries, and user-generated content (reviews). The FAQ section is particularly powerful — it targets question-based searches and can win Featured Snippets.
