What are other ways to advertise for a web site?

[Rabbit!]

My friend is the webmaster of an online site that sells vacuum supplies. The site hasn't been getting many orders since he revamped it for the store. It's one of the top search results for Google, and he's got the site loaded for Bing and Yahoo, and he made an ad for Google. He created a page for it on Facebook and tried advertising through his status a couple times, but the site hasn't been having much luck. We were wondering if there were any other ways to bring more traffic to the site that would be very cheap. Any ideas would be much appreciated.
