How to tell if a site is Shopify

If you are unsure if a site is Shopify you can simply go to the sites homepage and type /admin after the domain

After you type this in you simply click enter and if the Shopify log in page pops up then you have confirmed the site is Shopify

If that log in page does not pop up and you get a 404 or page not found error than the site is not Shopify and the guide for said site is likely listed here.
