# A/B Testing

> How to run A/B tests on content variants (Growth and Custom plans).

## Who Can Use This

A/B testing is available on **Growth** and **Custom** plans only. If you don’t see the Tests page, your plan doesn’t include it.

## What It Does

A/B testing lets you try different versions of content and see which performs better in AI answers. For example, test two headlines or two product descriptions and compare visibility scores.

## Why It's Valuable

* **Data-driven** — Replace guesswork with real performance data from AI models.
* **Higher visibility** — Use winning variants to improve how often AI recommends your brand.
* **Optimize before launch** — Test headlines, descriptions, and copy before publishing.
* **Cross-platform** — Results from ChatGPT, Claude, Gemini, and Perplexity in one test.
* **Clear recommendations** — Get a winner and guidance on which variant to publish.

## How to Create a Test

1. Go to **Tests** in the sidebar
2. Click **Create test**
3. Enter:
   * **Brand**
   * **Test name** — e.g., "Headline test for CRM prompt"
   * **Query** — The prompt to use (or pick an existing one)
   * **Variants** — 2–4 different versions of the content (e.g., different headlines or descriptions)
4. Click **Run test**

## What Happens

GeoArk AI runs the query for each variant and measures visibility. You can compare which variant gets mentioned more often or ranks higher.

## Use Cases

* **Headlines** — Which headline gets more AI mentions?
* **Descriptions** — Which product description performs better?
* **Landing copy** — Which messaging improves visibility?

Use the results to refine your content and improve AI visibility.
