They suggest (not me) it is primarily link oriented.
Links may be part, but I believe the way that it has happened is user metrics. Searches for brand name, time on sight, bounce rate, pages per visit. Take a look at the brands then take a look at your site. I would be surprised if you are beating the brand in these 4 areas.
