Hi currently we have two separate stores, one for Australia and one for the US. We are looking to merge the Australian store over to the US store and thinking to use subfolders e.g. migrating outstore.au to ourstore.com/en-au. The products and the collections in terms of URL structure will be the same between the countries, but there are some differences between the terms used in the US market vs. the Australian in how people search for the products so when we do SEO we are hoping we can have different titles, headings and some body content between the US and Australian versions. For example if we have a product in the US and AUS ourstore.com/product-1 and oustore.com/en-au/product-1 how can we have different titles for the product depending on the country. The same goes for the collections.
There may also be instances where we want to have a collection in one market but not for the other. How can we do that?
Also any guidance in general on steps we can do to make sure we migrate/merge without a big negative impact to traffic would be greatly appreciated.
