Okay you have a site that is fairly old and does well in Google. I hate using PR but lets say its a 5. The site lives on a MS server (It has to stay there). You want to build a Wordpress blog (yes it has to be wordpress) which SHOULD reside on a Linux server. You want to set it up as www.mysite.com/blog. If you put a 301 on so that users are redirected to the right place is there anything wrong that Google will see and is there any downside to it? Thanks!
Is it possible to do without redirecting? What about this option: Add a sub-domain, http://blog.mysite.com, and host the subdomain on the linux server. I'm not sure exactly how to set this up, but it can be done (something to do with DNS, A records, etc). Then you wouldn't have to worry about redirects at all.
I had though about that but not sure about it. I did not know if a subdomain can add to the sites size and content like a directory can. I always sort of thought of them as seperate site living on the same domain.
I think a subdomain would be a good option for you in this case. It can be seperate sites if you treat them that way, but you can also integrate the subdomain into your main navigation at just treat them as additional pages on the site.
