This document explains the process of running an A/B Test with Remote Config, using popup optimization as an example. Anyone can easily set it up by following each step in order.

## Optimizing Popup Components

Regardless of industry or service type, most services display a popup when users enter a screen. This document uses a popup displayed on the home screen as an example to show how to apply Remote Config and how it can be used in A/B Tests.

### 1. Managing the Popup with Remote Config

Assume you are running a Fri/Sat/Sun discount promotion offering up to 75% off, as shown in the image.

![Service screen example](/files/mU4THAz1gXNgyCx6r0Vu)

Go to Hackle's Remote Config tab > Create New Parameter > and create a parameter key named **Home\_banner**. Let's **configure the components in JSON as desired.**

As shown in the image below, include all popup components (image, title, description) in JSON and save. Changes are reflected immediately upon saving.

### 2. Running an A/B Test to Validate the Popup's Effectiveness

Previously, all users were shown a promotion copy emphasizing a weekend-only, time-limited offer.

Run an A/B Test against a version that emphasizes the maximum discount rate to measure its effectiveness.

* Original copy (Group A): Weekend-only, time-emphasized copy
  * "title": "Weekend Sale, Makeup Special"\
    "description": "3 days only every Fri/Sat/Sun! Maximum benefits! Spring exclusive special"
* New copy (Group B): Maximum discount rate emphasized copy
  * "title": "Up to 75% Off, Makeup Exclusive Special"\
    "description": "That product you've been eyeing — up to 75% off, the biggest discount ever"

### 3. Updating and Managing Condition-based Copy with Remote Config

Update the JSON in Remote Config. Set exposure rules and detailed changes to apply them immediately.\
**You can target A/B Test groups directly from Remote Config without having to reconfigure users.** Select the experiment key and update the copy for Group B as shown in the image below — changes are reflected immediately.

### 4. Confirming Results and Optimizing with the A/B Test

With the Remote Config changes applied, check the A/B Test screen to view results like the ones shown below.

Review the success metric (click-through rate on the main popup) for each variation, select the better-performing test group as the Winner, and apply it to your service.

This way, you can **run experiments without any separate code work using Remote Config**, and quickly optimize your service by reviewing detailed A/B Test results. (See [A/B Test Data Analysis](/en/ab-test/data-analysis/interpret-results.md))
