Hence, it is good if you have a low cost domain hosting if you have a low budget, but paid is preferable to the free services.
Domain names usually end with .com. However, there are other suffixes like .org, .edu, .info, .in, .net and so on, which are as popular.
Some suffixes indicate the business they are in like .edu will definitely be educational; .au is from Australia, .ro from Romania, and so on.
When you choose a domain name, you must keep in mind that it will represent you on the web. So, choose a simple and concise name, preferably one that reflects or is your brand name.
