When was the last time you changed your site's content? Even if it was just a page or two's worth? If you cannot answer this question, or without a long pause to think, then it is likely time to produce fresh content for your site.
Search engines and humans alike prefer to see fresh content vs. the same, stagnant content on your site. A site that sits with the same content on it for a year or more is a site that will struggle to truly succeed at search engine optimization.
Refresh the existing content now and then and make sure to generate new content a couple times a month, such as a blog, news, updates, etc. This is why an internal blog is great for SEO, search engines like to see that fresh content. Also, you can use this opportunity for images and more substance for search engine crawlers to index and grab when someone does an internet search related to your business.
