Why companies use ccTLDs instead of other top-level domains such as .com
Companies can use ccTLDs to target traffic from specific regions throughout the world. So, if you want to attract visitors from the United Kingdom to your bakery's website which is based in the UK, you might want to consider using the .uk domain extension. This ensures that you appear in search results for people in the United Kingdom, rather than Australia, Canada, or any other country.
This also has an impact on your Search Engine Optimization (SEO) value. When it comes to country-based search results, using a ccTLD provides you a greater SEO value. This is because search engines return different results depending on the IP address of the person conducting the search, including numerous local results.
This is the main reason why anyone would use a ccTLD (Country-Code Top Level Domain). Lastly, if you want a decent domain registrar, I recommend Nominus.
