I believe in the Google Sandbox effect. I've seen it with a site of mine. That's why I'm now booking many domains in advance and losing money.
Since a 301 redirect from a domain to another domain almost keeps the PR, link juice, and domain age, can't we use this technique to mitigate against the Google sandbox effect?
I have several idle domains that are years old. Just today I've booked a new domain and launched a site. Can't I simply forward any old domain to this new one to make Google to pass domain age etc to my new domain to help it come out of Google sandbox?
