Architecture & Crawl Control
Ecommerce Site Architecture
How to structure an online store's pages so both shoppers and search engines can navigate it — flat vs. pyramid, click depth, URL structure, internal linking, breadcrumbs, mega menus, faceted navigation, and mobile-first nav. Google reads your link graph, not your URL paths.
Related Products & Internal Linking
Related-product modules — 'You May Also Like,' 'Frequently Bought Together,' 'Customers Also Viewed' — aren't just merchandising. Every item is an internal link, which makes them a crawl-path and anchor-text asset. How to implement them so they help SEO: real <a href> links, descriptive anchors, relevance over volume, and reconciling cross-sell with orphan-page rescue — without scrambling your category hierarchy.
Faceted Navigation
Faceted navigation lets shoppers filter a category by color, size, price, and brand — and quietly spawns millions of near-duplicate URLs that waste crawl budget and dilute ranking signals. Here's how to decide which filter URLs to index and which to suppress, plus the canonical-vs-noindex-vs-robots.txt decision table.
Ecommerce Site Search SEO
The search box on your store is a conversion goldmine and a crawling liability at the same time. This is how to keep internal search results pages out of Google's index without breaking crawl budget, why robots.txt beats noindex here, when to turn a real search query into an indexable landing page, and how to mine your on-site search logs for keyword and content ideas.
Ecommerce XML Sitemaps
Generic sitemap advice breaks down at catalog scale. This is how to segment an ecommerce sitemap by type, stay under the 50,000-URL/50MB limits with a sitemap index, decide what happens to out-of-stock and discontinued product URLs, keep lastmod honest as inventory turns over daily, and pair sitemaps with IndexNow — plus why splitting by category is for monitoring, not crawl budget.
