i am planning to change my site urls and i dont want my old links which they allready indexed in google to be gone so i want to use this way to do and i am not sure about it.
i want to to redirect those links
http://domain.com/usa/mobiles-phones-pdas/ad/162/mobile-for-sale
http://domain.com/usa/mobiles-phones-pdas/mobile-phones/ad/162/mobile-for-sale
http://domain.com/usa/mobiles-phones-pdas/mobile-phones/blackberry/ad/162/mobile-for-sale
to be redirected to this url
http://domain.com/usa/ads-162.html
also the country ( usa ) it is not stick so it could be another country but the links are the same.
so which is the best SEO redirection method to keep my old links in google indexed.
