The domain name you choose for your website can have an enormous impact in how it's perceived by the search engines (even the age of your domain name matters), and by the people who use them. Buying a domain name used to be so expensive that they were the province of those who wanted to protect a brand name; now, they are affordable enough for anyone. In fact, if you look carefully, you could find a free domain name.
Now that it's so easy to get a domain name, most online searchers don't give a second thought to sites that do not have their own. Lacking a domain name, a company can seem less professional or be perceived as cheap. If you own a website and you don't have a domain name for it, you need to buy one.
The best domains are easy to remember- if your visitors remember your site's name, they are more likely to return. If you don't have a name for your company or site, then you should make your domain name and your brand one and the same. Doing so is a way to establish your brand and make your site's name easier to remember. Here are some tips on choosing an easy to remember domain name:
One of the obstacles to promoting a domain name is that most people (and some Internet browsers) assume that they all end in a .com. If your site uses another domain, then you should make it your site's identity, otherwise your potential visitors could end up on someone's site other than yours. If you buy your domain intending to make it your brand, then take into account keywords, especially if they are industry-specific.
If you are a business owner and you want to establish an online presence, than your choice of domain names is pretty short; usually it will be a variant of your company's name. Some extensions should be avoided because of how they've been used in the past- ending your domain with a .to, an .it, or .vu could cause your site to be taken less seriously.
Competition for good domain names is very high since the sharp decline in prices, so there's actually a good chance that the domain you want is already taken. The longer you wait to reserve a domain, the more difficult it will be to change it at a later date if you need to. Thankfully, most paid web hosts require you to use a registered domain, or to go through them to register one, which minimizes the above issues.
