Three common types of websites are: WordPress, templates and custom-built.
Our own website is an example of a WordPress site. Although you can host your WordPress site at their server ( www.wordpress.com ), for business purposes you will be better off hosting on your own server. This enables us to take advantage of all the customizations available in the WordPress themes. And, you can then make the best use of your own domain name.
Jentek Enviro is a site that was created using a basic template to start with, which was then customized to the needs of our client. There are thousands of website templates available. Using a template can cut down on design time while providing a great looking site with superb functionality.
And, for an example of a custom-built site, see www.koala-t.ca A custom-designed site will normally take a little longer to create, but may be the right thing for you if you cannot find exactly what you are looking for.
Any of these can be used for various functions: small business, e-commerce, blog, creative portfolio, community, social media, mobile, e-mail.
