Hi Jamal,
Glad to help with your questions.
Can this app be used to redirect from a Shopify store to a non-Shopify store?
Yes, it can. Shopify to non-Shopify is ok. But not the other way around -- you can't redirect from a non-Shopify store using this plugin, since it only works on Shopify stores. But yes, Shopify to non-Shopify is ok :)
Also, can it redirect to sub-pages? For example someone in the US visiting myshop.co.uk/collections/trousers will need to be redirected to myshop.com/trousers
Theoretically that is possible with some customisation. That's not how it works out of the box, but we have done that as a customisation in the past. We create a custom script that allows you to point to sub-pages using relative URLs, just as you mentioned above. This normally takes about 3 hours of development. Happy to discuss further if you'd like to contact us here: http://www.shopifyninjas.com/contact/
Two last notes:
- The relative URLs would need to be the same, e.g. myshop.co.uk/collections/trousers to myshop.com/collections/trousers (the /collections/ was missing in your example above, but I think I know what you mean :) )
- Just for clarity, this is a plugin -- a one-off installation -- not an app from the Shopify App store with a monthly charge. It's a once-off.
Hope that helps, let us know if you have any other questions.
Thanks!
Tristan.
