Shopify vs BigCommerce SEO: 3 Real Differences

Shopify vs BigCommerce SEO comes down to control, not capability. Both are hosted platforms with fast CDNs, automatic sitemaps, editable title and description fields and clean HTTPS. Neither one ranks you. The three places they genuinely diverge are URL structure, how a redirect behaves after you create it, and how much of robots.txt you are allowed to touch — and all three are decisions you make once, at build time, and then live with.

That is the useful framing, because “which platform is better for SEO” is the wrong question. The right one is: which constraints can you live inside, and which ones will cost you a migration in two years?

Shopify vs BigCommerce SEO: the three real differences

Here is the short version before the detail.

The last two rows are where most comparison articles spend their word count, and they are the rows where the platforms are effectively the same. Skip them. The first three are the ones that change what you can do later.

URL structure: fixed on Shopify, configurable on BigCommerce

This is the largest single difference, and it is permanent.

Shopify hard-codes its path prefixes. Every product lives under /products/, every collection under /collections/, every static page under /pages/, every article under /blogs/<blog>/. You can edit the handle — the segment after the last slash — and nothing else. Shopify also documents that you cannot create redirects from those fixed paths: /products, /collections and /collections/all are reserved. So the structure is not just the default, it is the floor.

BigCommerce exposes URL structure as a store setting. You choose SEO Optimized (Short), which produces yourdomain.com/page-name; SEO Optimized (Long), which inserts a segment such as /pages/; or Custom, where you assemble the pattern from placeholders separated by forward slashes — including ones Shopify has no equivalent for, such as the product SKU or its category.

Freedom here is genuinely double-edged, and BigCommerce says so in its own documentation: incorrectly modifying URLs can affect your SEO, and it recommends leaving the setting on SEO Optimized (Short) if you are unsure. There is a specific trap worth naming. If you include the category placeholder in a custom product URL, BigCommerce uses only the first main category the product is listed in. Re-categorise a product later and its URL changes — across a catalogue, that is a silent mass-rename.

Which is better? Neither, in isolation. Shopify’s rigidity means your URL structure cannot degrade through a bad admin decision, and it means every Shopify store on earth shares the same shape, so Google has seen it several hundred million times. BigCommerce’s flexibility is worth having if you are migrating from a platform with an established, indexed URL pattern you want to preserve exactly — that is a real and underrated migration advantage, because it lets you keep URLs instead of redirecting them.

Redirects: what happens after you rename something

Both platforms offer to create a redirect when you change a web address. On Shopify, changing a page’s URL presents a pre-selected “Create a URL redirect” option. On BigCommerce, a 301 is created automatically whenever the name or URL of a product, category or web page changes, and you opt out by unchecking it in the SEO & Sharing section of the editor.

The difference is what the redirect is made of. A Shopify redirect stores a literal pair: this old path goes to that new path. BigCommerce lets you choose. A manual redirect is the same literal pair; a dynamic redirect is bound to the resource — the product, category, brand, blog entry or page — so if that resource’s URL changes again later, the redirect follows it.

On a store that renames a product once, this is a footnote. On a store that reorganises its catalogue seasonally, it is the difference between a clean redirect map and a tangle of chains that you eventually have to audit by hand. If you are on Shopify and you rename things often, the mitigation is discipline rather than a feature: keep the redirect list as a source of truth, re-point old entries when a target moves rather than adding new hops, and use the CSV import to manage it in bulk. Shopify’s ceiling is generous — 100,000 redirects on standard plans, 20,000,000 on Plus — so the constraint is your own housekeeping, not the platform. Our walkthrough of how 301 redirects actually behave during a replatform covers the chain problem in more depth.

robots.txt: a template versus a setting

Shopify generates a default robots.txt and does not ship an editable file. To take control you create robots.txt.liquid in your theme’s Templates folder, at which point you can replace the entire contents with plain text if you want to. Shopify’s own advice is not to: it tells developers to keep using the provided robots Liquid object wherever possible, because the default rules are updated regularly to keep pace with SEO best practice. Override the whole file and you freeze those defaults at the moment you wrote them.

That is a sharper warning than it looks. A theme-level file that silently stops receiving platform updates is exactly the kind of thing that works for eighteen months and then quietly does not. BigCommerce keeps robots.txt as a settings surface rather than a theme file, with an API for it as well, which means it does not travel with your theme and cannot be lost in a theme swap.

The practical takeaway is the same on both: almost nobody needs to edit robots.txt, and the people who do usually need to add one or two Disallow lines for faceted or parameterised URLs. If your reason for editing it is “to improve SEO” in general terms, that is not a reason. We wrote about what Shopify SEO apps cannot fix partly because robots.txt.liquid is the single most destructive thing a well-meaning person can touch on a Shopify store.

What is identical, and where ranking actually comes from

Both platforms generate sitemaps you cannot edit. Both give you per-resource title and description fields. Both serve over HTTPS with automatic redirects from HTTP. Both handle canonical tags for you at the theme level. Both are fast enough that hosting is not your bottleneck.

Which means that once the three structural decisions above are made, the platform stops being the variable. What is left is the work that would be the same on any platform: the pages you choose to build, the internal links between them, the titles and descriptions you write, and the structured data your theme emits. If you want the Shopify-side version of that work, writing titles and descriptions that earn the click and getting rich results from Shopify’s structured data are the two that move things fastest, and you can sanity-check a draft snippet in our free SERP snippet preview tool before you publish it.

So which one should you pick?

Pick BigCommerce if you are replatforming from a system with a deeply indexed URL structure you would rather preserve than redirect, or if your catalogue genuinely needs SKUs or category hierarchy in the path. The custom URL pattern is the one thing Shopify cannot give you at any plan level.

Pick Shopify if you would rather not have that decision available at all. Fixed prefixes remove a category of mistakes, and the surrounding ecosystem — themes, apps, developers who have seen the same URL shape a thousand times — is deeper. For most merchants that is the better trade, which is why our full Shopify vs BigCommerce comparison lands where it does on fees, apps and total cost.

If you are weighing the two at enterprise scale, the calculation shifts toward B2B features and how the bill is built rather than URLs — that is covered in BigCommerce Enterprise vs Shopify Plus. And if you have already decided and the question is how to move without losing rankings, start with our BigCommerce to Shopify migration process, which treats the URL map as the first deliverable rather than the last.

Frequently asked questions

Is BigCommerce better than Shopify for SEO?

Not in general. BigCommerce gives you more control over URL structure and resource-bound redirects; Shopify gives you a fixed structure that cannot be broken and a larger ecosystem. Neither difference affects ranking on its own. Choose on the constraints you need, not on an SEO scoreboard.

Can I remove /products/ from a Shopify URL?

No. The prefixes are fixed platform-wide and Shopify does not allow redirects from the reserved paths either. You can only change the handle after the prefix. If a specific URL pattern is a hard requirement, that is an argument for a different platform or a headless build, not a Shopify setting you have not found.

Do I lose rankings migrating between Shopify and BigCommerce?

Not if the URL map is complete before you cut over. Rankings are lost to unmapped URLs, redirect chains and pages that quietly did not get rebuilt — not to the migration itself. Build the old-to-new map from a crawl of the live site, not from the export file.

Does editing robots.txt improve SEO?

Almost never. It is a crawl-control file, not a ranking lever. On Shopify it is also the riskiest file you can touch, because overriding robots.txt.liquid wholesale stops you receiving Shopify’s own updates to the default rules.

The takeaway

Shopify vs BigCommerce SEO is settled by three build-time decisions — URL structure, redirect behaviour and robots.txt control — and by almost nothing you can change afterwards. BigCommerce hands you the URL pattern and resource-bound redirects. Shopify hands you a structure that cannot go wrong and an ecosystem that is hard to argue with. Decide that once, then stop thinking about the platform and go do the work that actually ranks: build the pages, link them properly, and write the snippets yourself.
