What will rank higest in the Google?

Hi,
If I wanna rank high in Google for eg. the phrase "what is seo". What would be the best domain for me to have the article on?
what-is-seo.com / whatisseo.com - registered yesterday.
or
webmasters.com - 16 years old domain.
Both domains have the same amount of backlinks.
Thanks!

 

I would personally go with age and say webmasters.com unless you've done anything in the past which may have given that a bad reputation?

 

Okay. Thanks for your answer!
Other opinions?

 

What if webmasters.com is a bit more expensive?

 

whatisseo.com is worth the work. It may take some time but will benifit you in the future. Begin building the site and producing the need backlinks with the correct anchor text.

 

i would go with the aged domain but dont spend too much more because it is not worth alot more, whatisseo.com is a great name

 

I would go with the keyword domain, Google gives more favourable results to exact keyword domain names than age with all else being equal.

Also keyword domains have a higher chance of recieving sitelinks in the listings, example query "DigitalPoint", "SEOBook" etc.
