When you register a new domain, I am aware of the age deflation BUT one thing has been niggling me and I cannot find a definitve answer.
I choose to rename my site for one or two key reasons and plant the new look site onto the new domain. I then redirect via a htaccess 301 the old domain to the new location.
Does the new domain pick up the old sites status (links, PR, ranking etc)?
Thanks in advance OWG and anyone else who knows me...
I did a recent site change over, though I didn't change the main domain, I did do a lot of 301's for internal pages.
Google picked up on these straight away and within 24 hours all the new URL's where updated in the SERPs in place of the old ones. Pretty fast!
As for the page rank I read somewhere that a google guru said everything gets updated in a couple of weeks, but there was some disagreement on this and people were saying a couple of months.
I have never seen it take a couple of weeks. The reason it takes a little while for overall benefit to mve is because domain switching was the mainstay of black hat SEO. Domain A gets banned, 301 everything to domain B, and that ranks immediately, continue where you left off.
My experience is (depending on market competition), a few months, 2-4 normally.
