1) Cool.com
PageRank: Unranked
Alexa: Over 350,000
This domain is simply parked.

2) Hot.com
A single page with nothing on it except a lame colored logo. The sky is the limit for a domain like this.

3) Porn.com
PageRank: Unranked
Alexa: Unranked
This one is parked too but has a cool design. I’m guessing it’s making decent money, but no where near what a domain of this weight can bring in. Any regular developed porn site attached to this domain could make the profits hit the roof.

4) Sexy.com
After being presented with a warning page of enter or exit, the only thing you see next is a parked page.

5) Alien.com / 6) Ufo.com
These two can be put in the same category. With all the talk about aliens and ufo’s, these domains can be instant success.
Instead, Alien.com is a 404 page!!
And Ufo.com just a parked page.

7) Toy.com
PageRank: 0
Alexa: Over 3 million
An amazing 3 letter domain! Yet just another parked page.

8 ) Pal.com
Some sort of weird and unpopular search engine. Another great 3 letter domain put to waste.

9) Queen.com
Parked

10) Oral.com
Parked

11) Crazy.com
Parked. Could easily be used to feature all sorts of crazy videos or stories.

12) Pro.com
Wow! What can I say. A 403 forbidden! Some people would do anything just to have the word pro in front of another word in their domains, like proplayer or propoker…This person has the 3 letter by itself, and doing nothing!

13) Cash.com
PageRank: Unranked
Alexa: Over 2 million
Just parked.

14) Card.com
Parked for some credit cards. Could be used for a gambling site or a developed credit card site.

15) Super.com
Parked

16) Store.com
This thing could be something similar to eBay or Amazon, but it is just parked.

17) Cloth.com / 18) Clothing.com
Each of them could be the central location for anything related to clothing, but just parked.

19) Personal.com
A great domain for a dating site or personal resource information site, but parked.

20) Join.com
Parked

21) Fight.com
PageRank:1
Alexa: Over 1 million
Anything about boxing and UFC and mixed martial arts can be discussed here and it would easily be the #1 reference on the subject.

22) Gamble.com
PageRank: 3
Alexa: Over 8 million
Parked

23) Home.com / 24) House.com
One of them parked, the other one slightly developed. In the mortgage world, these domains can make more profit than anything else.

25) Dance.com
Parked.

26) Pay.com
Parked

27) Host.com
Parked. Can you find a better domain name for a hosting company?

28) Men.com
PageRank:3
Alexa: Over 250,000
Acquired for 1.3 million dollar and seems fully developed. However, a domain like this carries so much power that it is ridiculous it is not more popular.

29) Plan.com
PageRank:0
Alexa: Over 5 million
Parked

30) My.com
A 2 letter domain! Seems like an unsuccessful hosting company. This is the only 2 letter domain in this list, and man this is wasted.
