It is now possible to automatically localize customers visiting your store when your domain strategy is “primary domain only” or when you have a custom domain that is shared across multiple markets. If you have the “Automatic redirection” setting enabled within Settings -> Markets -> Preferences your pages will automatically adjust to show region-specific content based on your customer’s GeoIP. For example, if your store is example.com with a primary market of the United States and you have an additional market setup for Canada that is set to Primary domain only with CAD enabled, then a Canadian visitor will automatically see CAD pricing. When you have “automatic redirection” activated for your shop with markets set to “primary domain only” or custom domain strategy, non-primary market content is not indexed by search engines.
This is currently available to new merchants, and will roll out to existing merchants on September 6.
Note: To comply with local legislation, customers from the European Union (EU) aren't automatically redirected within the EU. More information can be found here.
