Is .co.uk or .com Better for a UK Online Store?
For a store that sells only in the UK, .co.uk is a safe, trusted choice. If you plan to sell abroad, a .com is easier to grow from. Here is how to decide and set it up on Shopify.
Key takeaways
- A .co.uk tells Google and shoppers your store is for the UK. Google calls country domains "a strong signal" of the target country.
- That signal works against you abroad: a country domain targets only one country, so a .co.uk is a weak base for EU, US or Australian sales.
- A .com has no country attached, so it works for one market or many, using Shopify Markets subfolders such as /en-gb/ and /en-us/.
- Buy both if you can. Shopify sells .co.uk and .com, and any extra domain you add redirects to your primary one.

For a store that will only ever sell to UK customers, .co.uk is the better choice: it signals a UK business to shoppers and to Google, and it's often available when the .com isn't. If you plan to sell outside the UK within the next few years, pick .com as your main domain and use Shopify Markets to serve each country. Owning both, with one redirecting to the other, removes most of the risk.
I build Shopify stores for UK brands, and the domain question comes up on almost every new build. The guidance below uses Google Search Central and Shopify's Help Center, checked on 7 November 2026.
What Google says about country domains
Google's guidance on multi-regional sites says country-code domains such as .co.uk "provide a strong signal to both users and search engines" that a site targets that country. A .com is a generic domain with no location, so if it targets one country, you tell Google through other means, such as hreflang tags or regional subfolders.
Google also lists the downside of country domains: each one targets only one country, costs more to run when you have several, and needs its own authority built from scratch. Nothing in Google's guidance says a .co.uk ranks better in the UK by itself. The signal helps Google understand who the site is for, and your content and links do the ranking.
.co.uk vs .com side by side
| Factor | .co.uk | .com |
|---|---|---|
| Country signal | Strong UK signal | None by default |
| UK shopper trust | Reads as a UK business | Neutral |
| Selling abroad | Weak base | Easy with subfolders |
| Availability | Often free | Often taken |
| Bought through Shopify | Yes | Yes |
How I'd decide
Choosing your main domain
- 1
Will you sell outside the UK in the next 2 to 3 years?
Yes: make .com the primary domainNo: go to question 2
- 2
Is the .com for your name available at a fair price?
Yes: buy both, pick one as primaryNo: go to question 3
- 3
Is the .co.uk available?
Yes: use .co.uk as your primary domainNo: rethink the store name
A good name on the right domain beats a forced name on a taken one.
If the .com of your name belongs to an unrelated US company, think twice before using the .co.uk. Shoppers who type .com by habit will land on someone else's site.
Setting it up on Shopify
- Buy or connect your domains. Go to
Settings > Domains. Shopify sells both .co.uk and .com, registered for a year at a time, with renewals billed separately from your plan. Shopify's list doesn't include plain .uk. - Choose your primary domain. The primary domain is the one customers see. Any other domain you add redirects to it, so a shopper who types the .co.uk still reaches your .com store, or the other way round.
- Add markets when you sell abroad. Shopify supports country domains, subdomains and subfolders on the Basic plan or higher. For a first international setup, Shopify recommends subfolders, because they share your main domain's ranking.
- Keep email consistent. Use the same domain for your business email as your store, so order emails match the address shoppers see.
If you're outside the UK
- Netherlands: the same logic applies to .nl vs .com. A .nl suits a Dutch-only store, and a .com with /nl/ and /en/ subfolders suits a store selling across the EU.
- Australia: .com.au is a strong local signal for an Australia-only store. A .com with an /en-au/ subfolder works if you also sell to New Zealand or the US.
- US: .com is the default, and US shoppers rarely see .us on stores.

Frequently asked questions
Does a .co.uk domain help UK SEO?
It helps Google understand that your store targets the UK, because Google treats country domains as a strong signal of the target country. It doesn't make pages rank by itself. Content, links and a good store still do that work.
Can a .com store rank well in the UK?
Yes. A .com has no country attached, so you tell Google who each page is for with hreflang tags and regional subfolders. Shopify Markets adds these for you when you set up a UK market.
Should I buy both .co.uk and .com?
If both are available, yes. Pick one as your primary domain in Settings > Domains, and Shopify redirects the other to it. That protects your brand and catches shoppers who type the wrong ending.
Can I buy a .co.uk domain on Shopify?
Yes. .co.uk is on Shopify's list of domain endings you can buy in the admin. Plain .uk isn't on the list, so you'd buy that from another registrar and connect it.
Can I switch from .co.uk to .com later?
Yes. Add the new domain in Settings > Domains and make it primary, and the old one redirects to it. Expect a short wobble in rankings while Google processes the change, so do it at a quiet time of year.
Is .uk better than .co.uk?
.co.uk is the long-standing UK ending most shoppers recognize. Both carry the same UK country signal, so the choice is about which version of your name is free and easy to remember.
