Ive been making changes to a old site Ive worked on, one of the tasks Ive taken is to change the url structure to something alot more friendly. For example pages currently work via query strings such as ?action=contact and ?action=article&id123. I am now changing them to /contact and /article/articlename respectively. I would just like to ask what approach should I take for the search engines so that they do not think that I have duplicate content.

Tabii ki örneğin ?action=contact, eski adresler destek olacak, ama kimse eski url eriştiğinde, onlar yeni birine yönlendirilir olmalıdır? Bu sayfa aynı zamanda bir 301 başlık verilmelidir?

Teşekkürler.
