within a 2 second look I can see your content is thin. Add more content and make the page more compelling.

add Pro theme.... more quality content... add dedicated IP with SSL... It will help to Outrank your competitors without SSL or dedicated ip... and it will also increase website loading time.

So it's a site with no real own content, and affiliate links to sales pages elsewhere? It shouldn't rank in the current form, and I'm amazed that you got it to rank in the first place.

It should be fairly obvious how to fix it. In addition to having some content, you should go through the HTML. The pages don't even have h1 tags.

You follow panda guidelines and start new decoration.
