I read that age of domain name also matters when the pricing is set on it. So how does age effects the domain name value? Lets say I have registered any haphazard domain name back in 1998 so would it be valuable right now after 9 years?

If someone registers a domain name right now and pays 10 years registration fees then will it be valuable after 10 years?

I am asking this so that I can invest some money in domaining market. Please give me some ideas on it.

Yes, it is true that domain age also affect on the price of domain. as a seo i know the value of domain age. You know google giving more weight to your domain if domain age it more. Google will consider your domain as a trusted one. and it will help you to get good search ranking.

There may be some truth to it, but if there is I think it's a very small factor as far as search engines are concerned.

I think the only value comes from what others think.

Part of the Google patent does mention consideration of how long a domain is registered for. The idea is that if a domain is only registered for one year, then it may be a spammer that is going to put junk on the domain and then dump it. Those that pay for more than one year should be more "serious". When word of the patent went out, there was a number of people that renewed for 5 or 10 years. Some registrars will let you register of as much as 100 years, which I think is insane.

The problem is that while the IDEA of considering registration length could be used, it doesn't that Google actually DOES. If I wanted to keep SEOs guessing, I would put all kinds of things into my patent and then not use all of it. And just because someone registers a domain for several years it doesn't mean they will continue to own it or keep the same site on it. If domain age is going to be considered, then than a SE can check the whois for the creation date and determine how long the domain has been owned by the current owner. Also, if I ran a search enigne I would keep a record of the domain like DomainTools.com does and know when the domain was first registered, if it ever expired, how many owners it had, and other information that may indicate how it has been used.

Whois Record
Domain Name: nielsentech.com
Registrar: Spot Domain LLC
Expiration Date: 2007-10-28 07:53:53
Creation Date: 1999-10-28 07:53:54

If domain age has any benefit, you think my domain would have better PR than zero...!

So, unless someone has some evidence of domain age having any "real" value, I think it should just be consided that the buyer will see some value to it.

The profit it can have to have an old domain is sometimes indirectly influencing its pagerank or the SERP's

For example if it is old domain then chances would be that it might have a website on it. The site would have been submitted and crawled by the search engines. Some years ago search engine submission was counted as a good way to increase the traffic. Nowadays search engine picks up the links and follows them from somewhere eventually finding your website from that links.

Another profit would be that there might be existing links for that domain name pointing towards it. That also from other old and established sites. In that period of time DMOZ was accepting sites quite faster then it is accepting right now. After that google directory started pulling the data from DMOZ and maybe a listing would be in the google directory also.

This were all the side factors.

If the domain name is really premium one then it doesn't matters when it was registered. New websites that have recently came into existence have climbed their way right to the top.

Quite a topic here as still today in SEO it that the older domain name is considered as the better domain name.

Age of domain is one of the important factor considered while advertising links, as older domains are considered as reputed domains and may have lot of backlinks and may have high PR if it is active.... I have seen many old domain which were just registered and put aside.....
