| Growth | 2 (add-on: Unlimited) |
| Enterprise | 2 (add-on: Unlimited) |

AMPL to AMPL real-time cohort sync, Approval Workflow, Group-level experimentation, Multi-armed Bandits, Stratified Sampling, and Winsorization are available as an add-on on the Growth and Enterprise plans.

Custom Code Editor, Experiment-level access control, and Experiment Results chart are available on the Growth and Enterprise plans.

Formula metrics is available on the Plus, Growth, and Enterprise plans.

Check your plan under [Plans & Billing in your organization settings](/docs/admin/account-management/account-settings#organizational-settings), or contact your Amplitude account representative._

Turn every page on your website into a testing ground for what works. Amplitude Web Experiment pairs a point-and-click editor with rigorous analytics so product, marketing, and growth teams can ship changes that move the numbers, without waiting on engineering.

**Outcome:** [Ship tests without an engineering ticket](https://amplitude.com/docs/web-experiment/set-up-a-web-experiment)

Launch experiments from a visual editor so marketing and growth move at their own speed.

**Outcome:** [Show each visitor the right variant](https://amplitude.com/docs/web-experiment/targeting)

Target by URL, behavior, and user property so the test reaches the audience that matters.

**Outcome:** [Test copy, design, and layout](https://amplitude.com/docs/web-experiment/actions)

Edit text, swap images, and restyle elements on the page itself instead of mocking up a new one.

**Outcome:** [Try a different page entirely](https://amplitude.com/docs/web-experiment/pages)

Run page-level experiments when one tweak isn't enough and you need to redesign the whole flow.

**Outcome:** [Prove the variant moved the metric](https://amplitude.com/docs/web-experiment/post-experiment)

Tie results to revenue, signups, or conversion so you know which variant actually won.

**Outcome:** [Personalize without rebuilding the page](https://amplitude.com/docs/web-experiment/out-of-the-box-widgets)

Drop in prebuilt banners and modals to tailor the visitor experience in minutes.

## Build web experiments

Use the visual editor to create page changes, redirects, and widgets without a full release cycle.

- [Set up a web experiment](https://amplitude.com/docs/web-experiment/set-up-a-web-experiment) to create the experiment, choose pages, and define goals.
- [Edit page elements](https://amplitude.com/docs/web-experiment/actions) to change text, images, styles, and layout.
- [Run page experiments](https://amplitude.com/docs/web-experiment/pages) to test full-page changes across matching URLs.
- [Use URL redirect testing](https://amplitude.com/docs/web-experiment/url-redirect-testing) when each variant needs a separate destination.

## Target and measure visitors

Connect web experiments to Amplitude data so each test reaches the right audience and reports on the right outcomes.

- [Configure targeting](https://amplitude.com/docs/web-experiment/targeting) to include visitors by URL, behavior, and user properties.
- [Track web experiments](https://amplitude.com/docs/web-experiment/tracking) to send exposure and interaction data to Amplitude.
- [Analyze results](https://amplitude.com/docs/web-experiment/post-experiment) to compare variants and make launch decisions.
- [Review performance guidance](https://amplitude.com/docs/web-experiment/performance) to reduce page impact from experiment code.
