301 redirect is the most efficient and Search Engine Friendly method for webpage redirection. It's not that hard to implement and it should preserve your search engine rankings for that particular page. If you have to change file names or move pages around, it's the safest option. The code "301" is interpreted as "moved permanently".Domain aliases is usually considered spamming to the
search engines because the domain name DUPLICATES the content on your
primary domain and in turn, masks the domain name under the secondary
domain. They may feel you are trying to trick them when you use a
domain alias. Because what they see when they crawl an aliased domain
is a website domain that has exactly the same content as the primary
domain.
