I agree with EGOL. I would take it a step or two further. I noticed you have reviews. Do you mark these up so they will be indexed by the review sites? Reviews can be p to 40% of your ranking if everything else is equal. So these reviews are an asset if you have them marked up properly.
The content as EGOL said is very week. This is hurting you in a couple ways. As EGOL has indicated Google will see this as a thin web site. The other (and I think bigger problem) is that there is not content or media that engages people. This is probably resulting in a low engagement that creates a low conversion rate.
It does not look like there is a lot of media on your web site. This is hurting you on searches as this is another way to be found. This is also hurting you on engagement and ultimately conversion (which is what people never focus on but should).
A few questions: 1) Do you have a physical store front? 2) Who are your main competitors and how do they rank relative to you 3) How many inbound links do you have relative to your competitors. 4) Is there a face or mascot for the company? People buy from people? 5) Is there a market positioning for the company and is this reflected in the content?
In other words there are a lot of things I would look at outside of what you are specifically asking about. I think if you fix some of these other things it would go a long way towards fixing the issues you are talking about. You may want to consider focusing on conversion optimization and coming back to SEO after this is addressed.
I hope this helps,
