# Testing RSA assets

Split-test RSA assets to compare how they perform

RSA asset testing helps you to compare how well specific messages perform.

Go to **Ad testing** > **Multi ad group** > **RSA:**

1. Select your campaigns and the date range for this test.
2. Specify the asset type and any pinning settings.
3. Specify the asset pattern you want to test. Patterns can be whole text or use wildcards (e.g. *Find a plumber in \**). **Click the icon** to see the top 20 RSA assets (by cost) across your chosen set of campaigns.

If you want Adalysis to run this test automatically every day, click **Save & run this test daily**. The test will then appear in the **Automated test definitions** tab and the daily test results will appear under **Automated test results**.

#### **How asset pattern matching works**

| **Asset pattern** | **How  asset text is matched to the pattern**            |
| ----------------- | -------------------------------------------------------- |
| abc               | **abc** is exactly as is.                                |
| \* abc            | **abc** is at the end of the text.                       |
| abc \*            | **abc** is at the beginning of the text.                 |
| abc \* xyz        | **abc** is at beginning and **xyz** at end.              |
| \* abc \* xyz     | **abc** is anywhere before **xyz** which is at end.      |
| abc \* xyz \*     | **abc** is at beginning. **xyz** anywhere after **abc**. |
