Leading search engines such as Google like dynamic sites, which regularly have new content added to them. The easy way to do this is to use a CMS (Content Management System). Arguably, the best type of CMS is one which you can access over the internet. This means that you are not bound to a specific machine, such as your laptop computer.
By having an internet-based CMS you will be able to login wherever you are and add new content to your website. If some disaster happens to your computer (i.e. a hard disk crash / it’s stolen), you can access your website from any computer with an internet connection.
In conclusion – having a CMS gives you a strategic advantage. Using one which is internet-based is the best choice.
