The BigCommerce vs Shopify debate comes up every time a merchant is choosing an e-commerce platform and SEO is a priority. Both platforms power millions of online stores and both claim to be SEO-friendly out of the box. The truth is more nuanced: BigCommerce offers more built-in SEO flexibility while Shopify compensates with a larger app ecosystem and faster default page speeds on newer themes.
This comparison evaluates the two platforms across the SEO factors that actually determine whether your store ranks: URL control, page speed, technical customization, structured data, content capabilities, and overall flexibility.
URL Structure Comparison
URL structure is one of the biggest SEO differences between BigCommerce and Shopify, and it favors BigCommerce.
BigCommerce lets you fully customize your URL structure. Product pages can live at the root level (/blue-running-shoes/) without any forced prefix. Category pages, brand pages, and content pages all support custom slugs. When you change a URL, BigCommerce creates an automatic 301 redirect from the old path.
Shopify forces a rigid URL hierarchy. Product pages always live under /products/product-name. Collection pages use /collections/collection-name. Blog posts use /blogs/blog-name/post-title. You cannot remove these prefixes on standard Shopify plans. Shopify Plus merchants can use custom storefronts to work around this limitation, but it requires a headless build.
Verdict: BigCommerce wins on URL flexibility. Shorter, cleaner URLs are easier for users to read and share, and they give you more control over keyword placement in the URL path.
Page Speed and Core Web Vitals
Page speed is a confirmed Google ranking factor, and Core Web Vitals (LCP, CLS, INP) are part of Google’s page experience signals.
Shopify stores run on a global CDN and benefit from automatic image optimization, lazy loading, and browser caching. Shopify’s newer Online Store 2.0 themes (like Dawn) are lightweight and score well on PageSpeed Insights. Median LCP for optimized Shopify stores falls between 2.0 and 2.8 seconds. Shopify’s Hydrogen framework (headless) pushes LCP below 1.5 seconds with edge rendering.
BigCommerce uses Akamai’s CDN for global content delivery. Stencil themes deliver server-rendered pages with median LCP between 2.2 and 3.0 seconds. BigCommerce supports automatic WebP image conversion and lazy loading. Performance optimization typically requires more manual effort than Shopify because Stencil themes vary more widely in code quality.
Verdict: Shopify has a slight edge on default page speed due to tighter control over theme quality and newer lightweight themes. BigCommerce can match Shopify’s performance with proper Stencil theme optimization, but it requires more hands-on work.
Customization Flexibility — Stencil vs Liquid
BigCommerce Stencil is a Handlebars-based template framework that gives developers access to template files, front matter for data injection, and a SCSS-based style system. Stencil themes are server-rendered and support custom JavaScript. Developers can modify every aspect of the HTML output, including meta tags, schema markup, and header structures.
Shopify Liquid is Shopify’s proprietary template language. It is well-documented and has a massive developer community. Liquid templates control the HTML output and support Shopify’s section and block architecture for drag-and-drop editing. However, Liquid is a closed ecosystem — you can only use Liquid within Shopify, and certain server-side customizations are not possible without Shopify Functions or a headless approach.
Verdict: BigCommerce Stencil offers more raw flexibility for SEO-critical template changes (schema markup, canonical tag logic, robots directives). Shopify Liquid is easier to learn and has more community resources but is more restrictive for advanced technical SEO modifications.
Built-In SEO Features
Both platforms include essential SEO features, but the details differ:
- Robots.txt: BigCommerce allows you to edit your robots.txt directly. Shopify auto-generates robots.txt and does not allow manual editing.
- 301 Redirects: Both platforms support 301 redirects. BigCommerce creates them automatically on URL changes and supports bulk upload. Shopify supports redirects through the admin and bulk CSV upload.
- Canonical Tags: Both platforms output canonical tags automatically to prevent duplicate content. BigCommerce gives more control over canonical tag behavior on filtered and paginated pages.
- XML Sitemaps: Both auto-generate sitemaps. BigCommerce includes products, categories, brands, and pages. Shopify includes products, collections, pages, and blog posts. Neither allows granular sitemap customization without custom development.
- Meta Tags: Both platforms let you customize title tags and meta descriptions for products, categories/collections, and pages. BigCommerce also supports custom meta tags for brand pages.
Verdict: BigCommerce offers more built-in SEO controls, particularly around robots.txt editing and canonical tag management. Shopify covers the basics but relies on apps for advanced SEO functionality.
Structured Data Support
Structured data powers rich snippets in search results — star ratings, prices, availability badges, and FAQ dropdowns that increase click-through rates.
BigCommerce includes built-in microdata for Product, BreadcrumbList, and Organization schema on Stencil themes. The implementation is template-level, so developers can extend it to include additional schema types like FAQ, HowTo, or Article schema for blog content.
Shopify includes basic structured data in some themes, but implementation varies by theme. Many Shopify stores rely on third-party apps like JSON-LD for SEO or Smart SEO to generate complete structured data. This adds a recurring monthly cost and introduces a dependency on a third-party app for a critical SEO function.
Verdict: BigCommerce provides more complete structured data out of the box. Shopify often requires paid apps to achieve the same level of schema coverage.
Blog Capabilities
Content marketing drives top-of-funnel organic traffic that feeds your product and category pages through internal links.
BigCommerce includes a built-in blog with basic functionality: posts, categories, tags, and custom URLs. The blog is functional but limited compared to a full CMS. There is no native support for content scheduling, advanced formatting, or content blocks.
Shopify also includes a built-in blog with similar basic features. Shopify’s blog supports tags, featured images, and custom excerpts. Like BigCommerce, it lacks the sophistication of WordPress or a dedicated CMS.
Verdict: Tie. Both blogs are adequate for basic content marketing. Merchants with serious content strategies on either platform often integrate a headless CMS or use a subdomain running WordPress.
Our Verdict: Which Platform Ranks Better?
BigCommerce offers a stronger SEO foundation out of the box. Customizable URLs, editable robots.txt, superior built-in structured data, and greater template flexibility give BigCommerce stores more control over the technical factors that influence rankings. For merchants who prioritize SEO as a primary growth channel, BigCommerce provides tools that Shopify locks behind apps or Plus-tier plans.
Shopify compensates with ecosystem advantages. Faster default themes, a larger app marketplace for SEO tools, and a broader developer community make it easier to find solutions quickly. For merchants who value simplicity and speed-to-market over granular SEO control, Shopify remains the safer default.
The best platform for your store depends on your priorities. If SEO is your primary acquisition channel and you want maximum control, BigCommerce SEO gives you the better toolkit. If you need a balance of simplicity and performance, Shopify is a strong choice. Either way, working with platform specialists — whether a BigCommerce development team or a Shopify development agency — ensures your store is optimized to its platform’s full potential.
