# Editor & Experiments FAQ

Quick answers about what you can test, how AI variants are generated, previews, and managing experiments in the editor.

## What can I test?

Text, headlines, CTAs, button colors, form labels, section order, spacing, and new elements like trust badges.

**Can't test:** Images, videos, navigation menus, or dynamic elements (prices, inventory).

## Can I test two elements together?

Not in one experiment. Use [URL Split Tests](/advanced/url-split-tests) to test multiple changes together.

## Why isn't my prompt working?

Common causes:
- Element is dynamic (price, size selector)
- Prompt is too vague ("make it better" vs "make this one sentence")
- Element is inside an iframe or web component

See [Troubleshooting](/faq/troubleshooting) for solutions.

## How do I preview experiments?

Use the preview link in the editor. For best results, right-click and open in incognito.

## Why does preview look different from live?

Preview has slight overhead for debugging. Live visitors see instant changes (<50ms). If very different, try incognito mode.

## Can I undo changes?

Yes. Use the undo button to revert changes. You can also delete a variant and create a new one if you want to start fresh.

## Can I copy experiments between pages?

Not in the UI yet. Note your prompts to replicate them manually. Copy feature coming soon.

## Does Dalton understand my brand?

Yes. The AI learns from your page. Add custom guidelines in [Brand Context](/editor/brand-intelligence) for more control.
