Google and the other search engines like websites that are constantly updated and have fresh and relevant content on them. Some businesses do this by adding additional pages to their main navigation or to additional boxes on the main web page but this can easily clutter up a website and make it unfriendly to users.
If you are looking for a way to and this all important new content then why not add a blog to your site. If you have a look of case studies or have a number of news articles relating to your business or even industry news then these too could be added to the website. The more content the better as they say content is king! Don’t forget, to write any information you take off the internet as simply copying someone else’s article and reposting it on your own could not only be an infringement of copyright but also cause your site to be demoted sue to duplicate content.
