Welcome to WebmasterWorld Guest from 188.8.131.52
My question is how do you get these extra links?
If you mouse-over those additional links, you'll see that these are redirected via Google. The URL includes (among other things) a trader variable. Although I can't be positive, it would appear that these are sponsored links.
I hope this helps.
If this is the case what is the world coming to?
Google could well be manipulating their results purely to make the aff links number 1. It does happen, I know because I do it with one of my directories ;oP
It has original content, many one-way links. It's a PR5, but beats a few PR7 and PR6. Besides the homepage, the extra links point to the most relevant pages of the site.
