Purchase Internet Domain
When you purchase Internet domain names for Internet marketing they should include appropriate keywords to obtain a good SERP (search engine results page). The idea is that you wouldn’t want to name your site DogCare.com if you are selling Real Estate. Also your personal name is going to be more difficult to draw traffic for a non-related product without a lot of advertising expense to create branding. Google heavily weights related domain names to keyword searches for SERP. Therefore, it’s a lot easier to include keywords in your domain to assure free search traffic and better SERP ranking.
Domain name registration costs around $15 a year and is usually discounted for 2 years or more. Some sites, such as, GoDaddy have discounts for 6 or more domain name registrations at one time. You can register a domain name with any registrar and have their DNS server point that domain to any other site where you might want to host it. I personally buy domains from GoDaddy and host them with HostGator. Most web hosting plans allow for unlimited domain hosting. You should try and use dot com which is the most popular extension followed by dot net or dot org.
