Old domain has several advantages 1) Trustworthiness of website 2) Known by search engines 3) Sometimes helps to achieve better search engine rank.

Old Domain does not guarantee rankings in Google. You need to have high quality backlinks from authorative sites and a high PR to get the worth of old domains.

The age of the domain is built up of how long the content has been actually on the web, how long the site has been in promotion,and even the last time content was updated.
So the age of the domain name plays a vital role in ranking.........
If you are having an old domain name...........that adds more credibility to your search engine rankings..
especially google gives more importance to domain age...........
So using this site www.WhoisXY.com , you can gather the information of the domain name creator and owner of the domain name also it displays the information of the domain name that is when is expired & created........its a easy way to find the age of domain name.........

Age is factor in SEO but if will be considered only in the well optimized sites..

Yeah I agree with your answer. Domain name does not matter a lot. Quality work will rock your website in SERPs.

Domain age is most important factor for SEO

There are many attributes that go into what shows up on the first page of the SERPS (Search Engine Results Pages) and one of those attributes is called Domain Age.

thanks for given information...

it is good for seo that your domain is old.Domain age is important as long as over the period of time it had some kind of content. If you had a domain but didn't have any website there, age will not make much difference. However if for example over the period of several years you had domain with some kind of content, the age will indicate that your site is reliable and it should help you score higher in SERPs.
