Using old domain names
By old here I mean a domain name that has been previously registered but has been allowed to expire and is available for registration again.
Now, assuming that the name matches the business requirements, there are two options to this I believe.
Option 1 : It may already have page rank and incoming links as a result of having been registered before. That is a potential benefit.
Option 2 : It may have built a previous reputation based on dubious SEO techniques with the aftermath still lingering around. That is a reason to avoid.
My own personal view is to start with a clean slate ie a name that has never been registered before. One that has some history may give an initial boost. Yet the likelihood is that things will crawl out later from the domains previous registration to haunt the web team.
What do others think?
