Custom widgets in Adobe Commerce Development can help make your store unique. To get started, use the built-in CMS tools to manage content easily. When adding widgets, use layout XML to place them exactly where you want them on your pages. Don’t forget to make sure they’re mobile-friendly, as many customers shop on their phones. For better performance, cache the widget content so your store runs faster. Keep the design simple and clean, and always test your widgets to make sure they work well with other parts of your site.
