When you pause or edit an ad from **Ad testing** > **Single ad group**, the test result is archived automatically. This means you have a **full history** of the changes you made.

If you haven't made any changes, you can still archive the test result manually.

Archived test results will record all changes from both the **automated or manual test result** screens. The results are visible at the account, campaign or ad group level.

Click any **Archived date** to see the test result.
