Should I choose a country code domain name (like .CO.UK or .CA), or a global top-level domain like .COM?
If your target market is specific to one country, I would recommend using a country code domain name, especially if you sell physical products that can only be delivered within that country. Many people I have spoken to tell me that they are often uncertain of where online stores are located, and it is not until they reach checkout and are asked to pay in a foreign currency that they are not able to order the products in their shopping basket due to the website not selling internationally. Having a country code domain name instantly lets your potential customers know that you are located in the same country as them, and that your service is designed specifically for that nation. Alternatively, if you have a website developed for the purpose of sharing information, with little or no content which is only relevant in one part of the world, my advice would be to choose a global top-level domain such as .com.
