The Complete Technical SEO Audit Checklist for E-Commerce Sites | AuditMySite

E-Commerce Sites Have Unique Technical SEO Challenges

A typical e-commerce site has 10-100x more pages than a service business website. That scale introduces problems: crawl budget waste, faceted navigation nightmares, duplicate content across product variants, and pagination issues.

We've audited over 200 e-commerce sites. This checklist covers everything we look for, organized by priority.

Priority 1: Crawlability and Indexation

Robots.txt Review

☐ Verify robots.txt is accessible (8% of audited sites have errors here)
☐ Product pages, category pages, and cart/checkout are NOT blocked
☐ Block internal search results pages
☐ Block filtered/sorted URLs
☐ Block session IDs and tracking parameters
☐ XML sitemap referenced in robots.txt

XML Sitemap Audit

☐ Includes all indexable product and category pages
☐ Does NOT include non-canonical URLs, 404s, or redirected URLs
☐ Uses <lastmod> dates reflecting actual content changes
☐ For 50,000+ URLs: sitemap index file with split sitemaps
☐ Removed products removed from sitemap within 48 hours

Crawl Budget Optimization

☐ Faceted navigation handled via rel="canonical" to unfiltered category
☐ Infinite scroll supplemented with ?page= URLs for crawlers
☐ Internal search results return noindex
☐ Session-based URLs consolidated or canonicalized

Priority 2: On-Page Technical Elements

Product Pages

☐ Unique title tags for every product
☐ Unique meta descriptions for top 100 revenue-generating products
☐ Canonical tags pointing to self
☐ Product variants handled via canonical to main product OR unique pages with unique content
☐ Breadcrumb navigation with structured data
☐ Product images have descriptive alt text
☐ Out-of-stock products remain indexed with alternatives linked

Category Pages

☐ Unique introductory content (150+ words)
☐ Paginated pages use proper ?page= parameters
☐ Internally linked from main navigation
☐ Subcategories link up to parent categories

Priority 3: Structured Data

Products with rich snippets see 25-35% higher CTR than plain results.

☐ Product schema on every product page: name, image, description, SKU, brand, price, availability
☐ AggregateRating if you have reviews (minimum 1 review)
☐ BreadcrumbList schema matching visible breadcrumbs
☐ Organization schema on homepage
☐ FAQ schema on category and product pages where applicable
☐ Validate all in Google's Rich Results Test

A strong brand presence helps structured data perform even better. Brand recognition plus rich data creates a powerful trust signal in search results.

Priority 4: Site Architecture

☐ Every product reachable within 3 clicks from homepage
☐ Logical hierarchy: Home → Category → Subcategory → Product
☐ Related products sections create lateral internal links
☐ Blog content links to relevant product and category pages
☐ Orphaned pages identified and fixed

Priority 5: Performance

☐ Product images in AVIF/WebP at quality 75-80
☐ Image CDN in place (Cloudinary, imgix, Cloudflare)
☐ Product listings lazy-load below-fold images
☐ Cart/checkout loads under 2 seconds on 4G
☐ Third-party review widgets and live chat don't block rendering

Priority 6: International and Multi-Location

☐ Hreflang tags correctly implemented
☐ Currency/region selection doesn't create duplicates
☐ Each language/region has its own XML sitemap
☐ Return/shipping policy pages exist per region

For businesses serving specific regions—like contractors in Sacramento—local SEO elements matter more than hreflang, but serving locally relevant content applies universally.
