Add a blog to your website.
A blog is a date based web publishing tool. It is an excellent way of adding new information like news stories, articles, press releases etc to your website.
One of the key benefits of a website is the ability to provide up todate information about you and your company to your potential customers. If you do not have the ability or knowledge to update your website yourself, adding a blog is probably the easiest and cheapest way of achieving this. A blog does take a little bit of effort to learn how to use, but not much, it is simpler than most website content management systems and well within the capability of most people.
The other good reason for using a blog over all other options is that the search engines like them. Search engines are now favouring social media and blogs so why look for a more complicated solution?
Search engines also particularly like websites that are updated regularly, a blog gives you the ability to do that easily.
