# Understanding Experiments

Plan, run, and review A/B tests in one place, from first idea to final result.

An A/B test (also called a split test) shows two versions of a page to different visitors at the same time, so you can see which one gets more conversions.

Go to **Optimize → Experiments**.

## Summary cards

| Card               | What it means                                          |
| ------------------ | ------------------------------------------------------ |
| **Active Tests**   | Tests running right now.                               |
| **Total Visitors** | Visitors included across your tests.                   |
| **Avg. Lift**      | The average improvement of variants over the original. |
| **Success Rate**   | The share of finished tests that produced a winner.    |

## Board and List views

**Board** organizes your tests by stage:

| Column      | What goes here                                                      |
| ----------- | ------------------------------------------------------------------- |
| **Ideas**   | Test ideas and learnings. Click **Capture** to add one.             |
| **Planned** | Drafts you've started. Click **Continue** to finish setting one up. |
| **Running** | Live tests, with visits and confidence so far.                      |
| **Decided** | Finished tests.                                                     |

**List** shows every test with its status, goal, control and variant pages, **Visitors**, **Lift**, and **Confidence**. Filter by **Drafts**, **Active**, **Paused**, **Completed**, or **Archived**.

**Lift** is how much better (or worse) the variant performs than the original. **Confidence** is how sure you can be that the difference is real and not chance. Wait for 95% before you call a winner.

## Create a test

Click **New Experiment**. Setup has three steps:

1. **Pick a goal:** what counts as a win.
   * Conversion: **Form Submissions**, **Click-through Rate**, **Destination Page**, **External Destination**, or **Revenue**.
   * Engagement: **Visit Time** or **Bounce Rate**.
2. **Pick a test type:**
   * **No-Code Element Testing:** change headlines, buttons, or images visually. No code or redeploy needed.
   * **Page-Level Testing:** send traffic to two different live URLs, for example two landing pages.
3. **Plan it:** add your hypothesis and expected numbers. Humblytics estimates how many visitors each version needs and how long the test should run.

Click **Plan a Test** to estimate test length before you build anything.
