A Shopify landing page is a landing page for your Shopify store. It has been created especially for the services and products that you intend to promote or highlight for your marketing campaigns. Ultimately, a Shopify landing page has been put in place to ensure that an end-user can easily perform a conversion action, such as filling a form, signing up for a service, or purchasing, right from the landing page.
So, your Shopify landing page is going to convert your visitors into buyers or leads. A typical landing page is going to have some Call to Action (CTA) buttons. They are in place to directly or indirectly get you more sales for your Shopify store.
A Shopify landing page is different from a Shopify homepage and is oriented towards driving more conversions.
