301 redirect is the most efficient and Search Engine Friendly method for web page redirection. Its simple to implement once you understand the process and it should preserve your search engine rankings for a particular page. If you have to change file names or move pages around, its the safest option. The code 301 is interpreted as moved permanently and it informs the search engine that the page is no longer at this location, it is over here now. In other words, it is much like a forwarding address at the post office for your mail.
