If you’re using Shopify to sell online, then you surely must know about the Shopify apps store. Shopify has a dedicated section where app developers have created extensions for Shopify stores that allow you to significantly improve both your eCommerce store’s functionality and sales. There are Shopify apps available for a multitude of purposes – from increasing sales by keeping potential customers longer on your site, to optimizing conversions, upsell apps, support apps, and many others. There are both free Shopify apps and premium ones available at the app store. Some even require you to pay monthly fees to keep them on your Shopify website.
