If you are a beginner in the area of SEO there is a great starter guide for you to begin with. It goes through all the basic elements of SEO such as using Meta Descriptions and Titles, optimising images and text, using titles and links and submitting sitemaps.  I recommend giving it a read and implementing the recommendations staright away to your website if you haven't done so already. It is never too late to optimise your website and the sooner you do, the sooner you can begin to climb search engines results. You can download the Search Engine Optimization Starter Guide here.
