--- title: Get started with Optimizely Web Experimentation slug: web-experimentation/docs/get-started-with-optimizely-web-experimentation docTags: createdAt: 2026-07-20T15:44:31.526Z --- - Optimizely Web Experimentation [Optimizely Web Experimentation](https://www.optimizely.com/products/experiment/web-experimentation/) lets you test experiences on your site with visitors, learn from them, and take action based on results. [A/B testing](https://www.optimizely.com/optimization-glossary/ab-testing/), also known as [split testing](https://www.optimizely.com/optimization-glossary/split-testing/), is a method of optimization that lets you run multiple versions of an experience to compare which is more effective at achieving your conversion goals. Visitors are randomly bucketed into one version, A or B. By measuring how visitors interact, for example, clicking a button, viewing a page, watching a video, submitting a form, or completing a purchase, you can determine which version is most effective at achieving your conversion goals. Optimizely Web Experimentation lets you configure and run A/B tests and other test types. In Optimizely Web Experimentation, these are known as experiments. The different versions of the page that a visitor might see are known as variations. ![editor.jpg](https://api.archbee.com/api/optimize/BrbvVORKJ5iIeSMZye5kI/BXMya-Gt19Ym6FDpsxIny-20260720-145153.jpg) :::hint{type="info"} **Note** See [Implementation checklist ](docId\:AARw7uTmrUJRM3dlVSmF4)to configure Optimizely Web Experimentation for longer-term success. See [Optimizely Web Experimentation resources ](docId\:BHUEHv24jhs5LuRXLN3EF)for information on configuring Optimizely Web Experimentation, building experiments, troubleshooting, and more. ::: ## Implement the snippet To start using Optimizely Web Experimentation, add [the small JavaScript snippet](docId\:jR-pX5bKreBi8ctWNBOko) to your site. 1. Go to **Settings** > **Implementation**. 2. Click the **clipboard** icon for the snippet you want to copy. :::hint{type="info" indent="2"} **Note** If your account uses [custom snippets](docId\:a3nBqUV00EHS6YncVXkrD), you might see more than one snippet listed. Choose the snippet you want to use for your experiment. ::: ::Image[]{src="https://api.archbee.com/api/optimize/BrbvVORKJ5iIeSMZye5kI/YT4fSw9l2OgzBgrugpd4j-20260720-145154.png" size="100" isUploading="false" showCaption="false" indent="2" width="1004" height="408" darkWidth="1004" darkHeight="408"} 3. Paste the snippet at the top of the `` tag of the page where you want to test or track a goal. Add the snippet sitewide for simplicity. See [Optimizing the performance of client-side experimentation](https://www.optimizely.com/insights/optimizing-performance/) for more optimization information. :::hint{type="danger"} Do not modify the snippet. Copy and paste it onto your site exactly as you see it within Optimizely Web Experimentation or Optimizely Personalization. Otherwise, Optimizely may not run correctly on your site. For example, do not add an `id="optimizely"` attribute to the script. ::: ## Manage collaborators, projects, and experiments :::hint{type="info"} **Note** If your organization migrated to Opti ID, you must manage users in Opti ID. See the [Opti ID user documentation](docId\:gfcl33i3WnqFAwFi9CT6y). ::: Users are called collaborators, and each type of collaborator has different permission levels. - **Administrators** – Full access to all projects and account billing information. A user who is an administrator on one project is also an administrator on every other Optimizely Web Experimentation project in your organization. - **Editors** – Can create and edit non-running campaigns. They can also view results. - **Project owners** – Can create, edit, publish, and pause campaigns. A project can have more than one project owner. - **Viewers** – Can preview campaigns and view results. :::hint{type="info"} **Note** See [Manage collaborators ](docId\:k85PWtJkIT0u2D-yW7_-I)for information. ::: Projects act as an organizational structure, letting you subdivide your Optimizely Web Experimentation account into territories for different sections of a website, multiple sites, or different products. Each project has its own snippet, set of experiments, and set of collaborators. Learn more about [creating and managing projects in Optimizely](docId\:pT9OPZKjArEKvmk__zj68). ## Get optimization ideas Read the following articles for testing ideas: - [10 common experiments and how to build them in Optimizely](docId\:PDm_kFdCs5LjfiwQl_bdU) - [35 leading companies share how they execute winning experiment ideas](http://optimizely.com/resources/experimentation-case-studies/?utm_source=knowledge-base\&utm_medium=website-direct\&utm_campaign=knowledge-base-big-book-of-case-studies) :::hint{type="info"} **Note** The book, [A/B Testing: The Most Powerful Way To Turn Clicks Into Customers](http://www.amazon.com/Testing-Most-Powerful-Clicks-Customers/dp/1118536096), provides many ideas and examples to get you started. ::: ## Build an experiment in six steps There are [six steps to create an experiment in Optimizely Web Experimentation](docId\:KiJTfQQjUsHKpV4igZ7Ea): 1. Configure [URL targeting](docId\:CXRLj-8Ogaa5pJZpIMdkq) or [pages](docId\:SLF-avIbJk1qR9hh8NU8_) where your experiment runs. 2. **Create** **variations** – Make changes to your site with the Visual Editor or custom code. 3. Add [audiences](docId\:IEjofkHOmT2__WUVZ4aSd). 4. **Add** [metrics](docId\:QMhSl6-5c54bbhHlZwMcp) – How you measure success. 5. **Set traffic distribution** – How traffic is split between variations. 6. [Test your experiment](docId\:G6SR7VF02w5hyw2yj0BLr) and [publish it](docId\:G6SR7VF02w5hyw2yj0BLr).
