Google give preference to old domain names, and those website with excellent reputation and backlinks still rank high in search engines
Old is Gold. If you have a old domain with high PR, you can even generate some revenue by selling it.
According to Matt Cutts, Domain Age is not main factor in Google Search Engine. The mains factors are backlins, fresh and unique content and page loading.
Domain age is one of the important factor in authority of host domain and while improve page rank and domain authority it plays an importnant role.
Domain age is an important SEO factor for your Google ranking. Among the hundreds of weighting factors that Google considers in determining how to rank search engine results is the age of your domain — in other words, how long that domain has been around.
Two things that are considered in the age of a domain name are: 1) The age of the website 2) The length of time a domain has been registered
The website age is one of the major factors used to rank a website. main advantage of having an older website is that site may have been added to the major search engines.
As your domain grow older your site become more and more important and authority. I have seen old domains with simple website but they have high PR.
Domain age is helpful for SEO but that domain should live from the day when you upload website on that particular domain, No change in content, website theme and no any redirection on that domain.
Not all that important, you can still rank without age, it's just with aged domain, it's more trusted, so you can build links more aggressively without being sandboxed in rankings. At least that's my experience building links for my clients.
Age of a domain is important because it help you define how trust your domain is. The older your domain are, it able to gain more trust from Google . It not only give you some privilege in SERP and Ranking. It help you not that easy to involve in Google Sandbox because your domain been in trust zone for some times.
One SEO related question which is often asked throughout webmaster forums is how much domain registration age is important for SEO. The points behind this question include: well-established sites have old domain names, so by reverse logics, an old domain should mean that the site is well established; spammers register and drop domains quickly, thus logically spamming sites usually have newly registered domain names. Generally, webmasters agree that domain age is hardly a powerful ranking factor but opinions vary: it can be no factor at all; it can play only a single minor factor in the millions of other factors (but it still is); it matters a lot (as most participants of this discussion seem to agree, for example). Google’s patent “Information Retrieval Based on Historical Data” of 03/31/2005 reviewed by Webmaster World forum hugely accounted for these rumors implying that Google does look into domain registration (1) and renewal (2) dates: (1) … the date that a domain with which a document is registered may be used as an indication of the inception date of the document.(2) Certain signals may be used to distinguish between illegitimate and legitimate domains. … Valuable (legitimate) domains are often paid for several years in advance, while doorway (illegitimate) domains rarely are used for more than a year. Therefore, the date when a domain expires in the future can be used as a factor in predicting the legitimacy of a domain and, thus, the documents associated therewith.While the patent does sound rather straightforward (by the way its official version is no longer available online, so it might have been deleted), domain age factor is both overestimated and misinterpreted. My point is simple: domain registration date cannot speak for either quality or trustworthiness of a website as: domains can be registered but never used for a long time (parked); new domains can be used for highly established companies (with the old domain 301-redirecting to the new one); a domain name can be used for illegitimate purposes for years and then sold to a “good” person/ company without any change of the initial registration date. Thus my verdict to the whole dispute is as follows: Website age (and its backlink profile age) is what really matters; Domain age can play a minor part only as damping factor – i.e. one of the factors signaling the search engine that this might be a spammy / illegitimate site; Old domains may carry more weight due to their past records (i.e. old backlinks pointing to them) – this can be a good point to consider but then again if you are serious about your brand, keep in mind that an established domain already has associations and history before you own it and they might be hard to conquer. Conclusion: domain registration date won’t of course hurt but it will hardly help. So I would focus on registering a new short niche-related and catchy domain name instead of trying to buy an old (previously owned by someone) one.
Domain age is among the Top 10 most important elements in Search Engine Optimization since having an old domain shows authority in search engines. But it doesn't mean that we don't need to provide compelling and well-optimized content. Google has improved its algorithm in monitoring "parked domains". There are lots of signals in rankings to work on so we should focus in all of those signals.
If you have a quality content and good quality backlinks then don't worry for SERP rank But according to Google , Age of the Domain also matters when calculating the value of a website. Moreover Age of Incoming Links, Age of Blog Topic etc. are also some factors to count the value of a Blog/Website.A domain that registered earlier has more consideration than new ones. Those Old websites are more authoritative, trusted and it has an edge over the Newbies
Not Much effect said by Google, but I am not sure I believe them. But anyway here is Matt Cutts from Google talking about the subject in 2009: and again in 2010:
Domain age is an important SEO factor for your Google ranking. Among the hundreds of weighting factors that Google considers in determining how to rank search engine results is the age of your domain — in other words, how long that domain has been around.
I find that - for local sites - they don't rank well for the first 3-5 months; then a site that's been sitting on page 2-3 will suddenly get to page 1. That's with no backlinks as most customers don't want to pay for a backlink campaign.
