We have been selling our product Quad Lock (iPhone mounting system) since 2012 by running a single Shopify store and selling globally in USD. This was fine for the first couple of years but as we grew we started selling through retail and with the fluctuations in currencies we had no option but to setup in multiple currencies to keep pricing consistent within our core markets.
After much consideration we decided to split our stores into region based stand alone stores selling in localised currencies with a smart IP redirect between all stores pushing the visitors to their region specific store. This was important because we knew our original .com store’s organic SEO was fairly strong worldwide and it could be years before the new localised stores outrank the .com in their intended regions. This would mean that many customers will still find the original .com store first and need to be pushed between stores to their correct regions site.
