Tools for testing
If things do not look right, the following resources can help you diagnose the issue:
- Preview tool – Helps you check the functionality of your experiments and campaigns, including how visual changes look for different audiences and when events fire.
- Network console – Helps you verify whether events in a live experiment or campaign are firing correctly. Use it to check that metrics are tracked correctly on your Results page.
- Optimizely Web Experimentation log – Helps you diagnose more difficult issues in a live experiment or campaign. It tells you whether an experiment or campaign activates on the page, whether you qualify for an audience condition, and whether changes on a page are applied.
- Optimizely Web Experimentation's cookies and localStorage – Uniquely identify visitors, track their actions, and deliver consistent experiences across page loads.
