# Defining Placeholders in the Portal

This guide walks you through how to set up both **Ad Surfaces** and **Branded Object Placements** using the web-based Portal. 

This is particularly useful if anyone *other* than your developer team members need to manage placements (or your developers need to make changes while away from their main computer).

{% hint style="warning" %}
Already working inside Unity, Unreal, or Phaser?

You can also define placements directly within your engine using the ReneVerse SDK. If you've gone that route, this section is optional.
{% endhint %}

### 🧱 What You'll Learn

* How to create and configure **Ad Surfaces** (for Smart Ads)
* How to create and configure **Branded Object Placements** (for in-world 3D brandable assets)
