# Introduction

Blocks are the foundation of Hubble. They empower you to create engaging, personalized content for your Shopify customer account pages. Hubble offers three categories of blocks designed to meet different needs:

* Static
* Dynamic
* Special

## How to choose the right block

* **What do I want to communicate?** [Announcements](/hubble/block-types/announcement-banner.md) and [Image Banners](/hubble/block-types/image-banner.md) are great for promotions.
* **What do I want customers to do?** [Featured Products](/hubble/block-types/featured-products.md) and [Order Item Actions](/hubble/block-types/special/order-item-actions.md) drive interactions.
* **What’s the best fit for my audience?** Use [conditions](/hubble/conditions/intro-to-conditions.md) to match blocks with specific customer groups.

{% hint style="info" %}
Not sure which block to start with? Begin with an [Announcement Banner](/hubble/block-types/announcement-banner.md) to try it out.
