Is .uk / .co.uk safe?
.uk / .co.uk is safe to use for websites and email. Legitimacy scams are about the site, not the extension — but .uk / .co.uk itself has a normal reputation with spam filters and browsers.
Is .uk / .co.uk good for SEO?
.uk / .co.uk is a country-code TLD, and Google may geo-target it toward its home country. If your audience is global, a generic TLD is the safer SEO choice; if your audience is local, .uk / .co.uk is an advantage.
