Hello, Which Company or Individual is promoting this website? About, and Contact pages are not to be seen. These pages add a lot of credibility, as you might be knowing.
The site looks a little unprofessional. Try hiring a couple of coders/gfxers and put a better layout in. Afterall, since it's a PPC site, there's no unique content, so it all depends on a unique layout.
I really think you should get a dot com name. WS loses credibility. Even dot net would be better. Something to think about.
You need to improve heavily on the site design. I would think twice before joining your website because it seems very unprofessional. Spend some money on the Website design and you will find more people interested in your service.
Dont even spend money. Just, take a look at a few different affilaites, and combine the ideas to create your own. Tip: Don't use the full screen layouts. Those often cant be seen by small monitors.
