BigCommerce SEO Audit — Find What's Hurting Your Store Rankings
BigCommerce-tuned audit catches the platform-specific defaults that hurt ecommerce SEO.
BigCommerce ships with stronger SEO defaults than most ecommerce platforms — clean URLs, Product schema baseline, sitemap.xml — but still leaves gaps that cost stores rankings. Faceted navigation generates duplicate URLs, default product schema misses critical fields, and AI bot access isn't explicitly granted. SEOGrade reads your live BigCommerce store and tells you what to fix in your theme and admin settings.
Common SEO issues on BigCommerce sites
Faceted navigation creating thousands of URL variations
Filter URLs like /shop/?color=blue&size=medium are crawlable by default. Without canonical or noindex, you get massive duplicate content competition with your real category pages.
Default Product schema missing required Google fields
BigCommerce emits Product JSON-LD with name and price, but commonly omits sku, brand, aggregateRating, and review fields that Google now requires for rich results.
Stencil theme bloat from un-optimized customizations
Custom theme code added to product templates often ships extra JavaScript and CSS that wasn't tree-shaken. LCP and INP suffer.
Multi-storefront content not properly hreflang-tagged
Stores serving multiple regions/languages need hreflang tags pointing at each language version. BigCommerce doesn't auto-emit them.
Account, cart, and checkout URLs leaking into sitemap
Default sitemap.xml can include /login, /cart, /account URLs. These are duplicate-content risks (every visitor sees the same empty cart) and shouldn't be indexed.
How to fix them
Block faceted URLs via robots.txt or canonical
Add Disallow rules for filter parameters in robots.txt, OR set canonical on filtered pages to point at the unfiltered category. We provide the exact rules.
Patch Product schema in your theme
Edit /templates/components/products/structured-data.html to include sku, brand, aggregateRating, and review fields. Use BigCommerce's review system or a third-party app to populate reviews.
Audit and minify Stencil theme assets
Run npm run lint and Lighthouse on a clean theme. Identify theme files adding the most weight; consider switching to Cornerstone or a lighter theme.
Add hreflang for multi-storefront setups
Use BigCommerce's Channel Manager + a custom script in the head to emit hreflang tags pointing at each storefront's localized URL.
Exclude account/cart/checkout from sitemap
Settings → Storefront → Sitemap. Confirm only product, category, brand, and content pages are included. Edit theme if necessary to exclude utility URLs.
