Ideally you should add a blog to your website if you have enough content to be able to update it on a weekly or monthly basis. Adding a blog to a website is differs depending on what system your site has been built with. To add a blog you will need to contact your web developer to build it for you. You should be able to have access to upload new articles on the blog without having to send them to the developer every time.

If you are using WordPress, then it should be straight forward to install a blog page. The blog can be stand alone or within your current site. If your site uses a custom theme then you may have to get your developer to make some changes to the layout, especially if you want a feed for your latest posts on the home page for example. ­
