Those look like the meta tags for each page Steve, the only one that has any relevance for SEO is the title, the description alters what Google displays for that page if your site is displayed in the search results and should be something that entices views to click on it . Keywords is irrelevant these days.
Get those updated to something that is relevant to the page but also includes some keywords about your product.
Next thing you need to do is add some page titles, I can’t see any heading (h1) tags on your home or about pages so doing that will improve things further.
It’s a bit ‘how long is a piece of string’ with SEO but Google really likes new, relevant content so if you can find a way of adding to the site on a regular bases this that would be another good boost.
Give me a call if you want talking through anything.
