In the past I used redirect 301 and in google was fine but in bing(Greece) the domain was disappeared. I want also now do 301 and redirect to new domain name, but I want to ask You. Is something change last time ? I don't want lost again my positions in bing. Maybe please tell me how Can I do that... In the past I did it something like that in index.php: <? Header("HTTP/1.1 301 Moved Permanently"); Header("Location: http://www.newdomainname.com"); ?> THank You for answers
Personally I would do a htaccess redirect. Anyway, yes, Bing supports redirects, but it might be a bit slower than other search engines.
Thank You and Yes now I know a htccess is better. But last time(few months ago) I lost all my positions in bing, so it working better now. I need to be sure because I don't want to lose my positions again.
You may very well lose your ranking for a period of time untill it has been fully crawled and reindexed, but in the long run it shouldn't matter.
