Some useful points that will help you choosing your domain and best practices:
1. Use your business name.
If your company name is "Keep Track Solutions", your domain should be "keeptracksolutions.com." Customers will assume your domain is YourBusinessName.com and type it into a Web browser. If they can't find it that way, it will make it harder for them to find you.
2. Be prepared for a challenge.
Generic names like pizza.com, food.com or art.com were among the first to go, and are now worth lots of money. Unless your company has an extremely unique name, you may be in for lengthy brainstorming sessions with your business partners as you consider alternatives.
3. Use dot.com as first option.
Having a .com at the end of your URL is not only expected for companies, it also indicates a degree of professionalism that extensions such as .org, us, .info, etc. don't carry much per our experiance if you want to be international, for e.g. using .it (Itlaian domains) your website will be very goo for Italy as search engines use localization.
4. Keep it simple easy to remember.
Shorter names are easier to remember than longer ones. They very good when use in radio and televisions advertisements and are less typing errors when your are searched for. Avoid dashes and other symbols, as well as obscure acronyms. "Keep in mind how your domain name sounds when you have to read it over the phone to a customer.
5. Register alternatives.
Just as Gary Pudles expanded his roster of URLs to include others that potential customers might type in, you should consider the same for your business. Doing so will keep customers from stumbling across a competitor's website. Most registrars forward secondary domains to your main URL for free.
6. Register your trademarks.
If your company makes a hair product called "CurlNGo," buy the domain name CurlNGo.com (as well as CurlAndGo.com, for that matter).
7. Consider keywords.
Buy additional domain names containing keywords that reflect your line of products or services and redirect them to your main site. This will improve your search engine rankings and bring you new customers. When doing online research, users tend to type in generic keywords such as "barbeque restaurant Atlanta" or "hair gel." To find the best keywords for your line of business, try Overture's inventory or WordTracker tools.
8. Use it.
Let everyone know your URL start from your business card, email signature, mailers, television spots, and letterhead. The more you use it, the more people will remember it and visit your site for updates.
9. Don't lose it.
This is the most crucial point of all. If you run a successful business and fail to re-new your domain name on time, you may resotre it before it expires. If expiration happens, you may be forced to buy back your domain at a high price from other people that monitor the expired domain to make good money. To avoid this scenario, register your domain for as long as possible and ask your hosting or designed company to follow up and keep it for you every year you can ask for certificate ownership for the webdesign company and also you can keep your credit card information on the domain financial record.
