How to fix seo variant urls in sitemap on BigCommerce
Remove product variant URLs (e.g. ?variant=, ?sku=) from your XML sitemap so only the canonical product page URL is submitted to Google.
Steps for BigCommerce
- BigCommerce generates its sitemap automatically at yourstore.com/xmlsitemap.php. By default it does not include variant query-parameter URLs — check whether a third-party SEO app or a custom sitemap script is adding them.
- Go to Apps → Marketplace, and review any installed SEO or sitemap apps. Open the app's settings and look for a 'Product variants' or 'URL parameters' exclusion setting and disable variant URL inclusion.
- For custom sitemaps built via the BigCommerce Storefront API or a headless front-end, edit the sitemap-generation script to filter out any URL containing query parameters before writing entries.
- BigCommerce automatically adds rel=canonical pointing to the clean product URL on all pages including those loaded with option/variant parameters — verify this by viewing page source on a variant URL.
- Resubmit your sitemap in Google Search Console: yourstore.com/xmlsitemap.php.
<link rel="canonical" href="https://www.yourstore.com/products/blue-t-shirt" />What is seo variant urls in sitemap?
When shoppers choose a color, size, or other option on a product page, many ecommerce platforms generate a new URL with a query parameter — for example, `/products/blue-t-shirt?variant=12345`. These variant URLs display the same product page with slightly different state; they are not separate, standalone pages. An XML sitemap is a file you submit to Google that lists the pages you want indexed. If variant URLs appear in that sitemap alongside the main product URL, you are effectively telling Google that each variant is its own unique page — which it isn't.
Submitting variant URLs in your sitemap wastes Google's crawl budget — the limited time Googlebot spends on your site — on duplicate or near-duplicate content instead of discovering and re-indexing your real product and category pages. It signals to Google that you may have a thin-content or duplicate-content problem, which can suppress your organic rankings. Google may also split ranking signals (links, engagement data) across the variant URLs instead of concentrating them on the single canonical product URL, weakening your page authority. Cleaning this up focuses all SEO value on one authoritative URL per product and keeps your sitemap lean and trustworthy in Google's eyes.
