If you intend to market to customers of a specific country or area of the world, you would want to use a area-specific TLD, rather than a .com, which indicates there is no set target for your market.

For companies that aren't trying to sell items, though, if your company's main presence is in the UK, for example, it would make sense to have a .co.uk domain.

When buying a domain, it’s important to understand that you must choose only Generic Top Level Domains (gTLD). These domains can help you stay competitive in search engines and will also increase your brand reputation. Why? Because these domains don’t target specific countries, and they are widely known.
According to Google, these are the Generic Top Level Domains (gTLDs) recommended if you want to compete worldwide. In this order
