I do believe Google Sandbox affect is there as I've seen with a site of mine.
That's why I'm booking many domains in advance and losing money ...
As far as I know a 301 redirect from a domain to another domain almost keeps the PR, link juice, domain age etc. Can't we use this technique to mitigate Google sandbox affect?
I mean I've several idle domains 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 that'd make Google to pass domain age etc to my new domain to help it come out of Google sandbox?
