It’s difficult to track down a definitive list of the most expensive domains because lots of these sales happen privately and don’t get recorded anywhere. But I managed to find a list here . This is the top ten:

1. sex.com – $12 million
2. porn.com – $9.5 million
3. business.com – $7.5 million
4. diamond.com – $7.5 million
5. beer.com – $7 million
6. casino.com – $5.5 million
7. asseenontv.com – $5.1 million
8. korea.com – $5 million
9. seo.com – $5 million
10. shop.com – $3.5 million

No surprise with number 1! Interestingly when you go to sex.com it will redirect you to another website. Work that one out!

I know we like a pint but is beer.com really worth $7 million? Visiting the site displays a sponsored results page and no internal pages. Are you trying to tell me that beer.com make all their money back by listing sponsored results on a one page site? Makes no sense to me.
