Frequently Asked Questions

Does GemPages include A/B testing?

Yes, GemPages includes built-in A/B testing on the Build plan and above. You can test different page versions and track conversion rates directly within the platform without needing a separate tool.

What is the post-purchase upsell feature?

The post-purchase upsell feature lets you create one-click upsell offers that appear after checkout but before the thank-you page. Customers can accept offers without re-entering payment details, increasing average order value.

Can GemPages replace my Shopify theme?

GemPages works alongside your existing theme rather than replacing it. You can use GemPages for specific pages like landing pages and product pages while keeping your theme for the rest of your store.
