It's an awesome and nice website idea (one product page). It looks great and arrive at the point, No fireworks, No popups or annoying ads. PERFECT... but you have to consider:
1- Remove duplicates from the pages titles.
2- Try to add more relevant content (Text Blocks with images relevant to your product).
3- Try to make BUY BUTTON more visible with eye-catching style (or add a background to it.)
4- You must check you page SEO (Google for Check Website SEO Score) to make sure it appears in search engines results.
Please add in your mind:
Finally, You'll be surprized with Nice Sales Volume and Commission $$$ :)
Good Work... Go ahead + Never listen to disappointing comments + Trust yourself.
Actually your site looks very vague and pretty much empty. I think when you create a website it will be better adding some products at the beginning itself as that is what creates an impression among the audience. This site is simple and smooth but a website should have some content in it and I guess you can work on that
