Old Design and URL Issues
The website doesn't look great, it seems to be built on an old templated CMS that has many outdated features in modern browsers. The menu items are a little buggy, the fonts are blurry, and the general usability isn't very smooth. This will increase the website bounce rate and cause them to rank lower in the search engines than they could with a better site.
Added to that they have an automatic homepage redirect to /home/ which isn't canonicalised, causing duplicate content issues.
They are also missing basic on page information such as H1 headers on the homepage, which could be optimised for their target keyword to increase their rankings.
