There are plenty of places online where you should purchase site names. GoDaddy, DomainCheapsters are a couple of the most typical, and one’s I’ve personally used. If you’d like to find more just visit some web marketing forums and ask for opinions, or do a search. Site names are cheap often around $10 a year at the most. Many sites offer sales or multiple domain discounts . There’s a lot of opposed views about whether or not you need to get any domain with a different extension such as .net or .org as an example. Personally, I will use a .com, .net or .org. You will need to find what is best for you, but you need to remember something : many folks will say that patrons will forget a long URL or a different extension, which is correct but how does one target the great majority of your clients?
If you are not handing out business cards and expecting them to type in the domain name than it is not such a big issue. Take the time to create your net presence, don’t get bamboozled into assuming that going the ‘free’ route with a blog is the easiest way to go.
