Both .co.uk and .com are popular options, but each has their own specific advantages. UK businesses may prefer .co.uk, whereas .com offers wider international appeal.
As there are fewer registered .co.uk domains than .com, it also offers greater choice and availability. You are more likely to find the name you want with .co.uk than .com.

For businesses targeting UK customers, a .co.uk domain offers a strong advantage: local trust.
Research from Nominet - the registry that oversees all .co.uk domains - shows that 81% of UK consumers would choose a .co.uk domain over a .com one. This highlights how strongly British consumers associate .co.uk domains with familiarity and reliability.
In addition, .co.uk is deeply embedded in the UK market. There are over 10 million registered .co.uk domains, making it the standard choice for British businesses. This widespread use reinforces credibility - customers expect UK companies to use it.
Business benefits of .co.uk:
Best suited for:
The .com domain is the most widely recognised extension in the world. In fact, it accounts for around 44-47% of all registered domains globally. This dominance makes it instantly familiar to users everywhere.
As .com is not tied to any specific country, it is ideal for businesses aiming to reach an international audience. It also carries a perception of being more 'global' and, in some cases, more established.
However, there are trade-offs. Due to the popularity of .com domains, many desirable names are already taken. This can make it harder (or more expensive) to secure your ideal domain.
Business benefits of .com:
Best suited for:
Choosing between a .co.uk and a .com domain is a common decision for businesses targeting online visibility, but its impact on SEO is often misunderstood. While the domain extension does play a role, it's just one piece of a much larger puzzle.
Google does not inherently favour .co.uk over .com (or vice versa) when it comes to overall ranking power. A well-optimised .com site can rank just as strongly as a .co.uk site.
One of .co.uk's best advantages is its geographic relevance. It signals to Google that the website is specifically intended for users in the UK, which can give businesses targeting UK customers a slight edge.
The choice of domain extension is a minor ranking factor compared to the fundamentals. High-quality, relevant content and strong backlinks remain the dominant drivers of SEO performance. A .com site with excellent authority will easily outperform a poorly optimised .co.uk site.
Ultimately, the choice comes down to your business goals. A .co.uk domain is ideal if you're focused on the UK market, as it reinforces local relevance and trust. On the other hand, a .com domain is better suited for brands with international ambitions, offering broader appeal and flexibility across multiple regions.
The Q4 2025 Domain Name Industry Brief highlighted continued growth in domain names, with nearly 387 million registrations in total. Of those, 161 million were .com domains - demonstrating that the enduring appeal of .com continues to make it the world's most popular domain extension.
The report also demonstrated that .uk in general (of which .co.uk is a part) remains one of the top 10 largest country-specific extensions, with over 10 million total registrations. Notably, it also showed relatively strong performance in retention, with renewal rates outperforming many alternatives.
In summary, .com continues to lead in scale and steady growth, while .co.uk, as part of the broader .uk extension, demonstrates resilience and high renewal rates, reinforcing its importance in the UK digital ecosystem.

In this video you'll find out:
If you're choosing between a .co.uk and a .com domain, you're not picking a right or wrong option. You're choosing the signal that best fits your customers and where you want your brand to grow.
A .co.uk domain immediately tells people your business is based in the UK or primarily serves a British audience. For many UK customers, that local cue feels familiar and trustworthy, especially when they're choosing who to buy from online.
A .com domain has global recognition. It is the extension people expect to see, whether they are in London, New York, or Singapore. That makes it especially appealing if you are building a brand with international ambitions.
Side by side, .co.uk often feels more local and grounded, while .com can make a brand feel broader and more internationally positioned. Neither is better in absolute terms - it depends on who you are trying to reach and where you want to grow.
From an SEO point of view, .co.uk and .com domains can both rank well when your site has strong content, sound technical setup, and relevant links. The extension does give Google a signal about geographic focus, which can help with local UK searches if you are using .co.uk, but it is not the decisive factor in most ranking situations.
That is why many businesses register both. It helps protect the brand, avoids confusion, and stops someone else from snapping up the other version. And because .co.uk names tend to have more availability than .com, you are more likely to find the name you actually want.
If you are just getting started, names.co.uk offers a free .co.uk domain for one year. When you are ready, search for the right domain on names.co.uk.
A .co.uk domain has a number of advantages over .com for UK businesses. These include:
While both .co.uk and .com are recommended for any UK business, .co.uk remains the domain extension of choice for the UK market.
Buying both .co.uk and .com domains can benefit you in a number of ways:
In summary, securing both .co.uk and .com allows you to protect and grow your business online.
.com is the world's most popular domain extension, but popularity may not necessarily equate to trust. Research from Nominet - the UK's domain overseer - revealed that UK consumers are more likely to choose a .co.uk domain over a .com one. For this reason, if you are a UK business than a .co.uk domain can be seen as more trustworthy than .com.
There is no evidence that a .co.uk domain will rank any better in general than a .com one. However, it shows to Google that you are in the UK. Therefore, your domain will be more likely to appear in location-based search queries (eg 'plumber near me')
A .co.uk domain can often be registered very cheaply for the first year, usually for less than £1. However, this low intro price is often tied into accepting a multi-year contract, with higher prices for the subsequent years. Some exceptions to this are names.co.uk and LCN, who offer a free .co.uk domain for one year, with no contract needed.
A .com domain can usually be registered for less than £5 for the first year, but this low offer price is sometimes tied into a multi-year contract with higher prices on the following years. At names.co.uk and LCN a .com domain can be bought for £1.99, with no fixed contract or additional purchases necessary.
If your UK business is expanding overseas then it makes sense to broaden your geographic appeal by also registering a .com domain. If the overseas market will become your primary audience, it is best to switch your main domain to being the .com one. Be aware that it may take time for Google and other search engines to update their records, so some initial instability in your visibility may come about.
Here is a quick summary on whether .co.uk or .com is better for SEO:
Outside of location-based searches the choice of domain extension generally plays a minor role in SEO and is just one ranking factor among several.
