If you plan to use SEO as your main or one of your main marketing strategies, it won’t matter which domain name extension you choose. Both the .com and the .net will perform very well.
Originally, .com was meant to represent commercial or business website. However, it now represents just about anything under the sun. This is by far the most popular and the most recognizable of the domain name extensions. The .com domain extension is the best choice for offline advertisement, too.
If you follow the theories of the many experts, using the .net for your primary business domain isn’t a good idea. However, if you run into the issue of the .com not being available, the .net may provide a second choice. Just make sure the owner of the .com doesn’t have a trademark on the name you’re after.
Whenever possible, you want to use the .com for your primary domain, especially with a business. Since the .com is the default domain extension for most people, it provides many benefits you don’t get from a .net domain name.
Have you ever tried to remember a website you heard on a radio commercial or from a billboard? When you go to type it in with the .com extension, however, it doesn’t work. It could have been a .net, but our minds are trained to assume most domain names are .com, especially businesses.
