# Define pages, audiences, labels, and tags

Give project work a consistent vocabulary for targeting, categorization, and filtering.

Project definitions let your team describe work consistently instead of repeating slightly different names on each item. Select the intended project, then open **Settings → Project → Definitions**.

## Pages and audiences

A **Page** identifies a website area relevant to research or experiments. An **Audience** identifies a visitor group. Create entries with recognizable names and enough description to distinguish similar concepts.

1. Open **Pages** or **Audiences**.
2. Choose **New page** or **New audience**, complete the fields, and save.
3. Link the definition to work that concerns it.

Use **Import Pages** or **Import Audiences** when the selected project has a provider with discoverable data. An import creates or maps a definition; it does not prove that an experiment on that page has run. See [testing platform integrations](https://conversionlab.app/docs/integrations/testing-platforms).

## Labels and tags

**Insight Labels** provide a named, colored classification for insights. **Tags** provide reusable categorization; choose the tag type offered by the editor for its intended use. Use the same definition when two items should appear together in filtering and review.

Edit existing definitions from their settings table. Deletion dialogs identify permanent changes; check linked work and update your team's naming convention before removing a definition others use.

## States and metrics

Idea and experiment states describe progress rather than evidence. Their customization is governed by plan availability; see [states and workflows](https://conversionlab.app/docs/ideas/states). Metrics define what you measure and how improvements should be interpreted; see [metrics](https://conversionlab.app/docs/concepts/metrics).

If a selector is empty, confirm that the definition exists in the selected project and that filters are cleared.
