1 What makes ecommerce SEO different?

Ecommerce sites face unique SEO challenges that standard sites do not. Thousands of product pages with similar content. Category pages with faceted navigation creating duplicate URLs. Product schema that must be correctly structured to appear in Google Shopping. Out-of-stock products that may need 404 or 301 treatment. These are ecommerce-specific problems that require ecommerce-specific solutions.

The opportunity: Most ecommerce sites have significant structured data gaps. Adding valid Product schema with price, availability and reviews to every product page unlocks rich results — price and rating stars displayed directly in Google search results — which dramatically increase click-through rates.

2 The most common ecommerce SEO errors

  1. 1Invalid price format in Product schemaPrice must be a numeric value — not "£29.99" but "29.99" with currency set separately as "GBP". Invalid price format prevents rich results entirely.
  2. 2Missing availability propertyEvery Product schema block must include availability — "InStock", "OutOfStock" or "PreOrder". Without it, Google may not display your product in Shopping results.
  3. 3No AggregateRating on product pagesIf your products have customer reviews, add AggregateRating schema. This adds star ratings to your search results — one of the highest-impact ecommerce SEO improvements available.
  4. 4Faceted navigation creating duplicate URLsFilter parameters like ?colour=red&size=large create thousands of near-duplicate URLs. Use canonical tags or robots directives to prevent indexing of filtered URLs.

I audit ecommerce sites every week. The pattern is consistent — stores with complete, valid Product schema outrank identical stores without it, because the rich results they unlock generate more clicks, which signals quality to Google. It is a compounding advantage.
