I have been reading your email newsletters and web postings for quite awhile
now and am hoping you may be able to help me.
I work for a technology company and we run our website in-house. We make
small website changes just about every week where we regenerate a few pages
at a time. At the beginning of October we regenerated our entire site and
ran into a very strange problem. All of a sudden all our search results were
showing up under one of our old domain names. This old domain still exists
because we have multiple domains in the same server with the same IP
address. These domains are all pointing to the same content.
However, we have one main domain that we actively use and that almost all
our website traffic normally comes through.
Do you have any ideas or could you point me to someone who may be able to
help? Your help would be greatly appreciated.
You’ll want to set up a 301 redirect from your old domain to your new, which
should fix things. See the 301-redirect thread mentioned previously.
However, if your new domain is less than a year old, you may wish to use a
302 redirect temporarily due to possible Google “aging delay” issues.
