Integrate Google Optimize into your Webflow project to run A/B tests and other experiments — create a better experience.
Google Optimize [↗] enables you to test variations of your websites and web pages for free. You can run tests on your content to understand what works best for your site visitors. You can use Google Optimize for A/B testing as well as running multivariate and redirect tests.
You can integrate Google Optimize on any of your Webflow projects from your project’s integration settings page after you enable Google Analytics on that project.
Note: Slow site speed is a known issue when integrating Google Optimize (users generally experience a performance decrease of 50 percent). You can remove the integration and republish your project to prevent it from negatively affecting your site speed.
Check out these resources to learn more about Google Optimize:
Visit the Google Optimize [↗] homepage, create a new container, and copy the container ID.

Return to your project’s integration settings and paste the Optimize container ID you copied.
To disable Optimize on a project, delete the container ID, save changes, and publish your site.
To use Optimize, you'll also need to integrate Google Analytics into your project. So, if you haven’t already integrated a Google Analytics Tracking ID, go ahead and do so on the same Integrations settings page of your project.
Learn more: Setting up Google Analytics
This integration links your Google Analytics property to your Webflow project. You can also link the same Google Analytics property to Optimize to access data about running experiments in Analytics.
Learn more: Link Optimize to Analytics [↗]
Now that you’ve integrated Google Analytics and Optimize into your project, you can start running tests using Optimize. Publish your site to get started.

A/B testing is a simple method of running optimization tests on your website. To run an A/B test, create two different versions of a web page that differ in one way, such as having different headings. Then, split traffic between the two versions and watch your analytics to see which version (A or B) produces better results. It's important that you only change one element of variant B. Otherwise, you won't know which change led to better performance!

Split testing, or redirect testing, is a different type of A/B testing. Redirect tests allow you to test two different landing pages (different URLs), for example a redesign of your homepage.

Unlike A/B testing, multivariate testing (MVT) allows you to test many elements on a page at the same time. This is helpful to understand if many sections of a page work well together.

Optimize Diagnostics will notify you when there are potential issues with your integration. Optimize lets you know what the issue is so you can make the necessary changes to resolve it.

If Analytics tracking code is not found on your site, or Analytics pageview is not detected, or an Unsupported Analytics tracking code is found on your site:
If a Wrong Google Analytics tracker is used to load Optimize, it means you’re most probably not linking the same Google Analytics property that you’ve integrated into your Webflow project to Optimize. To fix this issue, make sure you’re using the same property Tracking ID in your integration in Webflow as the one you’ve linked to in Optimize.
If the issue is none of the above, and Optimize tells you that there's an issue with how Optimize is installed on your website (code or snippet issue), please contact us and we'll help resolve it.
