Really the only single site than would cause significant ranking improvements would be some paid SEO service, some paid service use short term strategies that due to Google's standards changes, can actually harm your site's long term ranking.

There is no single site that will magically boost your site traffic and ranking, a typical SEO campaign (to get search engine traffic) involves on site improvements as well as getting links from a diversity of other sites (not just one) at a steady pace, even one new links a day can help a site over time.
