E-commerce SEO
SEO practices specific to online stores — covering product page optimisation, category page architecture, faceted navigation management, and schema markup for products and reviews.
Definition
E-commerce SEO is the application of search optimisation principles to online stores. The unique challenges: (1) **Scale** — thousands to millions of product pages, many with thin or duplicate content (identical product descriptions from the manufacturer); (2) **Faceted navigation** — filter/sort interfaces that generate parameter URL explosions and crawl budget waste; (3) **Product schema** — `Product`, `Offer`, and `AggregateRating` JSON-LD that enables rich result eligibility (price, availability, and star ratings in the SERP); (4) **Category page optimisation** — category pages are often the highest-value pages for commercial queries but are treated as thin navigation pages with no editorial content; (5) **Seasonal content** — keeping product pages live for discontinued or seasonal products (with updated content and new stock notices) rather than deleting and recreating the URL each season.
Why it matters for SEO
For e-commerce sites, SEO is often the largest source of high-intent traffic. Product pages rank for transactional queries ("buy running shoes size 9 blue"); category pages rank for commercial queries ("women's running shoes"). Common e-commerce SEO failures: (a) auto-generating title tags as "Product Name - Brand Name" without a keyword-first template; (b) using manufacturer-supplied product descriptions verbatim (duplicate content across thousands of sites); (c) not adding `Product` JSON-LD with price and availability (missing rich result eligibility); (d) deleting sold-out product pages instead of redirecting to the category or a "notify me" page (losing the page's accumulated link equity); (e) letting faceted navigation generate millions of crawlable parameter URLs.
How DeepSEOAnalysis checks this
The audit detects e-commerce signals (product pages, shopping patterns, add-to-cart flows) and applies e-commerce-specific checks: `Product` schema presence and validity on product pages, `AggregateRating` completeness (required for star rating rich results), faceted navigation canonical handling, product page thin content (less than 200 words of unique description text), and out-of-stock handling (404 vs. 301 vs. 200 with in-stock alternatives). Category pages are checked for editorial content depth (pure navigation pages with only product listings are flagged as thin-content risks).

Faceted Navigation
Filter-and-sort UI on category pages (color, size, price, brand) that generates a combinatorial explosion of parameter URLs — the most common source of crawl budget waste on e-commerce sites.

URL Parameter
A key-value pair appended to a URL after a `?` character — such as `?sort=price` or `?page=2` — that can create thousands of duplicate-content URLs if not handled correctly.
