E-commerce SEO Has Unique Challenges
An e-commerce site with 10,000 products has 10,000 potential landing pages. That's either 10,000 opportunities or 10,000 sources of duplicate content and crawl budget waste. The difference depends on your technical SEO implementation.
Product Page Optimization
Unique Product Descriptions
The number one e-commerce SEO problem: manufacturer descriptions used verbatim across hundreds of retailers. Write unique descriptions for at least your top-selling products.
Product Schema Markup
{
"@context": "https://schema.org",
"@type": "Product",
"name": "Product Name",
"image": "https://example.com/product.jpg",
"description": "Product description",
"brand": {"@type": "Brand", "name": "Brand Name"},
"offers": {
"@type": "Offer",
"price": "49.99",
"priceCurrency": "USD",
"availability": "https://schema.org/InStock"
},
"aggregateRating": {
"@type": "AggregateRating",
"ratingValue": "4.5",
"reviewCount": "127"
}
}Sites with complete Product schema see 20-35% higher CTR in search results.
Category Page SEO
Category pages often drive more organic traffic than individual product pages. Add 300-500 words of unique editorial content — a buying guide introduction, key features, popular subcategories.
Faceted Navigation and Crawl Budget
Faceted navigation generates unique URLs for every filter combination. A category with 5 sizes, 8 colors, and 10 brands creates 400+ filter URLs.
Choose which facet combinations deserve indexation:
- Index: Facets that match actual search queries ("blue running shoes")
- Noindex, follow: Facets without search demand but containing links to follow
- Block via robots.txt: Sorting options, price ranges, multi-select filters
Out-of-Stock Products
Don't delete the page or return a 404. Keep the page live with an "out of stock" message, suggest alternatives, and offer email notification. If permanently discontinued, 301 redirect to the most similar current product.
Internal Linking
Add "related products," "customers also bought," and breadcrumb navigation. Every product page should show the full category path: Home → Category → Subcategory → Product.
Review Schema and UGC
Product reviews add unique, keyword-rich text and provide fresh content signals. Implement AggregateRating and Review schema. Star ratings in search results dramatically improve CTR.
