Short answer. For a business that mainly serves UK customers, .co.uk is familiar and trusted, and .uk is a shorter alternative. A .com suits businesses selling internationally. If both are available, many businesses register both and point one to the other.
When .co.uk makes sense
- You mainly serve customers in the UK.
- You want people to see straight away that you are a UK business.
When .com makes sense
- You sell to several countries.
- Your brand name is free as a .com and you want one address everywhere.
Owning more than one
- Register the endings people are likely to type.
- Use one as the main address and redirect the others to it, so you never split your visitors.
Questions
Is .uk the same as .co.uk?
They are separate domains. Both are UK endings; .uk is shorter, .co.uk is better known.
Does Google prefer one?
Google treats .co.uk and .uk as UK-focused. A .com has no country, so you rely on your content to show you serve the UK.
