If you have a website then you should already be aware of how important fresh content is. Content is king and the more relevant, unique and fresh content you have on your site the better. Some people think that they can just copy and paste articles or blog posts from other sites to add to their own, but this is not the way to do it and is certainly a step in the direction of getting your site banned. Google says that any content added to your site must give the viewers benefit. So for example if you wanted to reference another article that is ok as long as you add your own input to it as well.
News sections are usually a good way to get new content on as this should be unique to your business. You don’t have to worry about writing a 2000 word essay, a few hundred words a few times a week may be enough to give you the bump you need. The news could be about things that are happening within your business or about industry changes and advances that your visitors may find interesting.
