Hello, I had no idea that there where so many domain names. I understand that domain names with 4 letters are the most popular, is this true?

they are good for SEO yes

No, the most popular (read: valuable) are generics that receive targeted type-in traffic.

4-letter.com's got big because a.) all the 3-letter .com's were taken, b.) 4 letter pronounceable domains, usually consonant-vowel-consonant-vowel, are very brandable and became popular in the web2.0 community

All the CVCV.com's are taken now anyway, though they do come up for sale relatively often. Not my cup of tea personally, but lots of people love 'em.

i've heard lot about four letter domains and i saw a guy selling the left 14 four letter domain at ddb

It all depends on your goals... if you're looking to develop a site and fill it with quality content it won't really matter if your domain name has 4 or 5 letters in it. You want something memorable for sure, though. I'd rather have a 5 letter pronounceable domain than a four letter domain made up of j,x,z,q,v, and letters like that. Above all though, I'd like a generic one word domain that gets lots of type in traffic... anyone have one of those?

Maybe you can pick up a 4-letter general .com,

it can be useful for making many sites of general purpose.

In short, 4-letters .com will become more valuable day by day.

4-letter domains come up on expired domains all the time. They are not usually pronouncable though, but sometimes are.

2 letter and 3 letter.com domains are most expensive, but they are not available.

what about 3 Letter and one Number Like A1AA.COM? are domains like that valuable?

yes A1AA.com can be valuable. Short domains are great for search engine ranking.

try to stick the keywords you try to rank for in your domain names.

For instance: www[.]red-widgets[.]com if you sell red widget.

thanx for the infos

I got very confuse about these three letters and four letters domain etc.I would like to know more about these domains so that i could have proper knowledge about it and could purchase a suitable domain for my web site.
