I'm going to move a site which i have kept in a SubDomain to a New domain name. the site receive like 10,000 uniques per month. How should I do it with minimum impacts on seo ? If I leave a redirection to new domain how long page serp would stay for subdomain ? Even the domain would receive the traffic from subdomain would it be sandboxed ? Roughly how long new domain would take to recover and start getting its own traffic ? Please share your experience about this.
It would be a new start I would say. You gonna loose SERP rankings, some traffic as well. If you could make a 301 redirect for every page that would at least save your SERP to some extent. If thats too much to do, do it for most important pages. I would suggest keeping the subdomain website alive but it should redirect to the new page. This is how I did it http://forums.webcosmo.com to webcosmofroums.com
There are like 400 pages But i think 301 redirect would be the best way to do it. I wonder wut if i keep both sites put and put 301 to pages one by one till i do for all pages ? I would penalize by Google for duplicate content ?
If you are doing 301 redirect for each separate page you would not get penalized. Because 301 is meant to tell the SE that a page has been moved permanently to a new location. The example I showed you is not using a 301 redirect; rather its a sitewide redirect. If you wanna do 301 redirect I would suggest doing it on every page you like to redirect.
If you want to keep your ranking and pass PR to new site, i would suggest to go for permanent redirect. I did it for one of my site and PR was passed in last PR updates. You have to redirect all the pages one by one.
whats about the serp ? didn't your new domain get sandboxed ? Anyway I guess permanent redirect is the only way. Could tell what did you put in .htaccess file ?
