I've got a large UGC site with 100,000 pages covering a wide range of topics. It's been quite profitable in the past, but it has been hit hard by Panda. Despite a large dedicated core membership and a large number of organic backlinks, I can't say that it will ever rank well in Google again.
I've let go of all my employees and my wife got a job working for someone else. What's left is just barely enough revenue to justify me working on the site full-time.
The site also has a terrible name, which doesn't reflect any part of what the site does anymore. I've wanted to change domain names in the past, but there was too much at risk. Now that I'm the only one depending on revenue from the site, I'm revisiting the issue.
I'm under no illusion that changing domain names would release this site from Panda's grip. The thing is, I love what this site does, I feel like it's a benefit to society and it helps quite a few people. I'm happy serving the core membership there with my time, but I still need to pay my bills.
Sorry for the long story, but I'm wondering if anyone has recent experience with switching domain names and the resultant Google rankings. My understanding is that it takes about a week before the old listings disappear, followed by around a week of very low traffic. If all goes well, two weeks after the switch, traffic will return on the new domain.
I am technically adept and I'm confident I can get the proper 301's in place. I heard Matt Cutts talking recently that 301's don't pass 100% of the link juice, which kinda scares me. Is there a rule of thumb to expect, like maybe 80% of the traffic to return?
Any insight you can give would be appreciated.
