I am doing some work for a company that has the same website on two different domains. The huge problem here is the duplicate content issue. We are going about re writing the text of one of the sites (they are both huge).

Firstly I would like to address the name of the pages:
example.com/widget
example.co.uk/widget

Now, should I be changing the name of one of them to something like example.com/online-widgets?

Also all of the images have exactly the same names. I would think this would also prove to be a problem in the future? Is is good enough just to change the alt text? Or should I rather change the name of the image and the alt text.

Thanks for any advice!
