i spoke previously about 301 Permanent Redirects and how they are an effective way to maintain/pass along your site’s PageRank and inbound links to the new site and/or landing page.
one thing i’d like to mention is that with regard to 301’ing a site/landing pages from one domain to a completely new domain, Google may take some time to resolve this update within its algorithm.
for example, if your “old” site is:
and the new site is:
and you’ve 301 redirected the home page of the old to the home page of the new and redirected all the major landing pages to the new site’s URL structure.
a change in the actual domain name may cause up to a 2-3 month lag in resolution within Google. scary indeed.
patience is definitely a virtue here.
the typical results i’ve seen after the resolution is a return to previous site rankings/traffic followed by marked increases in the months to follow.
