Markets make currency and catalogue localisation easier. Domains and hreflang decide how search engines treat regional versions.

Practical rules

• One clear primary URL per market
• Hreflang that matches live Markets configuration
• Unique content where language or offers differ — not only a currency swap

A .co.uk storefront helps when the offer, shipping, or content is genuinely local. It is not a ranking switch by itself.
