If you were a consumer who some how managed to find a way to your website what would be your first reaction?
Personally I wouldn't stick around for more than a few seconds. The website looks like it's over a decade old and that would give me the opinion that you have either abandoned the project or that you put just as much effort into the product you are selling as you have put into your website.
Now I'm not saying that you should go out and blow 10,000 grand having a website designed, but seriously you could learn to create a better website in a weekend.
You have some good marketing concepts on your website but the dated design and awkward placements of everything just makes most of it useless. Just to hit on a few good things that you're wasting with a crappy design.
Scarcity can be used to make sales. You have scarcity on your website in the form of one sentence that is built into the middle of the page. Might as well put it in fine print below the fold. Look into something like Hello Bar where you can move it to the header in big bold text that will pop for customers.
Your call to action is very bland. Don't be afraid to spam people with call to action. Look up Ryan Deiss over at Digital Marketer (I suggest you subscribe to his newsletter to really see his marketing in action). When he's writing copy or sending a letter he will repeat a call to action four or five times. Seriously his copy writing is sometimes like this
"My product does xyz so you should go ahead and click the buy button now. Also the product has this type of return policy and that is awesome so go ahead and find that buy button now. Additionally if you're looking for a great way to do xyz go ahead and click over here for that buy button. If this all sounds great to you go ahead and click that buy button." Copy writing is a skill, that people pay BIG bucks for, so obviously you'll want to test out many different call to actions to see what converts but don't be afraid of asking for the sale multiple times.
Explainer videos are awesome! People love them. They build brands, they inform customers and all around they are just fantastic. The one you have is solid enough, just doesn't fit with your current website.
Really I could go on and keep listing things that really need to be fixed but almost all of them go back to your website not being set up for success.
