# Test a group of pages

Experiments → New experiment → A group of pages: name a group, choose its pages with URL rules, check which pages it covers, and start one test they share.

Pages with too few visitors for a test of their own learn faster together. A group puts similar pages, such as your service or comparison pages, into one test they share.

1. **Start a group**

   In **Experiments**, select **New experiment**, then **A group of pages**.

   _Screenshot: The New experiment dialog: Where do you want to experiment? with One page, A group of pages and Catch-all._

2. **Name it and choose its pages**

   Type a **Group name** (1). Under **Include pages matching any rule**, pick **URL is**, **URL starts with** or **URL contains** (2) and type the address (3), such as `/services/`. **Add rule** adds another; a page that matches any rule is in. Under **Exclude pages**, **Add exclusion** leaves pages out. Type an address in **Try a URL** (4) to check whether a page matches.

   _Screenshot: The group’s rules: Group name marked 1, URL starts with marked 2, /sales-demo/evolve/ marked 3, and Try a URL marked 4 reading Matches your rules._

3. **Check the matching pages**

   **Matching pages** on the right counts the pages the group will test and lists each one. Pages with a test or winning opening of their own keep it, marked with a shield, and don’t join the group.

   _Screenshot: Matching pages: 2 pages included, 3 keep their own test or opening, with the protected pages marked by a shield and the included ones by a tick._

4. **Start the test**

   Select **Review and start** (2) to check the group, then **Generate and start test**. Darwin writes a new opening for the group and tests it against the opening those pages show today. **Save for later** (1) keeps the group without starting a test.

## Good to know

- A page is in only one test at a time. A page tested on its own, or one with a winning opening of its own, stays out of the group.
- Rules can’t change while the group’s test runs or while openings are being written.
- The **Catch-all** test covers every page that isn’t tested on its own or in a group.
