Opt Out of Optimizely Tracking

What is Optimizely?

Optimizely, Inc. offers a range of website analytics services for A/B and multivariate testing purposes. Optimizely partners implement Optimizely as a way to better understand how their website is used.

Use of Cookies

Our service uses cookies - a small text file containing a string of alphanumeric characters - to identify a visitor's browser and track website usage while on a partner site. The cookies come from partner website domains and from our log subdomain. You can reset your web browser's cookies to clear these cookies. For more information, see our full privacy policy. You should also consult the privacy policy of any particular partner website to see what other analytics they use, and what details they track.

Opt Out

If a website is using Optimizely and you wish to opt out, you can use a special command to tell their Optimizely code to stop tracking you.

This will set a cookie on your browser, from the client domain, that prevents you from being placed in any future Optimizely experiments on that domain. This will also prevent that website from making any Optimizely tracking calls for your visit. Importantly, if you reset your cookies, you will clear the opt out cookie as well. Thus, you may want to reset your cookies before setting the opt out cookie.

Generating the Opt Out URL

The opt out command is a query parameter appended to a website's URL. Specifically, use the query parameter optimizely_opt_out=true. To auto-generate the opt out URL, copy the URL of a webpage using Optimizely into the following input field. Then click on the generated link.

If it worked, you will receive a notice stating that you have opted out of Optimizely experiments on that website. If you have trouble getting it to work, you can contact us at hello@optimizely.com.

Auto-generate an opt out URL

1. Enter the URL of the webpage:


2. Click the following link:

Include this snippet on every page you want to run experiments on and track as a goal. This snippet will not change. Note the //cdn prefix is NOT a typo.

To add new projects, go to the Dashboard.

Each project has a unique Project Code snippet that must be included on every page running experiments or being tracked as a goal.

Your account has more than one project, so be sure to add the correct snippet. To view your projects and project codes, go to the Dashboard.
