i redirected one of my domains like Jon.com to Mike.com after about 2 days Jon.com is not in google anymore, i stoped redirecting and made the front page redirect to the new site in 10 seconds so the bots have enof time to scan the page how long would it take to get added back in the index again i lost some good keywords i have 360 backlinks
you should use a 301 permanent redirect. this will ensure that your links stay intact and everything gets passed along to the new domain.
