There are two types of WordPress web site platforms: WordPress.com and WordPress.org. WordPress.org is the version I use as a professional web developer.
For examples of WordPress web sites I have built, go to the Portfolio page and click on the CMS WORDPRESS PLATFORM heading. For examples of HTML web sites I have built, go to the Portfolio page and click on the NON-CMS HTML PLATFORM heading.
WordPress.com versus WordPress.org……
WordPress.com is NOT the platform that I use. WordPress.com is a do-it-yourself platform where you can set up a free blog or web site using their domain… something like mysite.wordpress.com… with advertising displayed on your site and very limited options. This is not usually a good fit for a business but would be okay for a personal blog.
Alternatively, WordPress.org is the “all-the-bells-and-whistles” professional version that I install on your own hosting, using your own domain name. The .org version is the platform that I am referring to on this site. It is a set of software that I install on your hosting plan that provides the foundation for your professionally created and unique web site.
