We recommend that you discuss the redirection of any expired domain with your SEO provider.
We use a 301 redirect to point any purchased domain to your existing website.
A 301 redirect is a method of telling web browsers and search engines that a web page or site has been permanently moved to a new location. Usually a 301 redirect includes the address to which the resource has been moved.
A 301 redirect is a permanent redirect which passes between 90-99% of link equity (ranking power) to the redirected page. 301 refers to the HTTP status code for this type of redirect. In most instances, the 301 redirect is the best method for implementing redirects on a website.
Despite rumours to the contrary, google has indicated that when you use a 301 redirect you do not have to worry about losing any more PageRank than you would through a link. This means that the 301 does not hurt performance.
