FAQ about Shopify Apps

What apps should I use on Shopify?

With thousands of apps on the app store, store owners can add any app to their online store, as long as it’s compatible with the ecommerce platform Shopify. The Shopify app store is an intuitive place to search for what you need, check out the listed apps, and install the app in one click.

Your store’s design, combination of apps like email pop-ups or offers, and studying your conversion rate over time will be the best strategy to convert site traffic.
