camshaft: Well I hate when other sites do it, but it does work. Using text the same color as the blue page background, you can add hundreds of bang and olufsen related words at the bottom. This way google sees them but people normally dont. What bugs me is sites will often include words that aren't directly related to the site, but close enough that they hope the traffic will still help them. When I use google I usually view the cached page though rather than the main link, so it becomes obvious when a site does this.
Have just been googling a bit. BeoWorld comes out tops on Everything Bang & Olufsen. (There's a fun one a bit down the page: "Everything Bang & Olufsen does is expensive".)
The site should push Enthusiasts, Fans, Fan site, fansite, repair your B&O, get advice for Bang & Olufsen, etc. - in the way camshaft points out, in order to increase hits.
The product pages will help, as people begin using them. But I agree that it would be smart to have overview pages - now one has to know quite specific things in order to find a product. I like the way Tim Jarman has done this - combination of visuals and text. That kind of functionality will increase traffic.
