1. What Happened to Google Optimize?

Google Optimize and Optimize 360 stopped working on September 30, 2023, as Google's Optimize help center confirms. Any experiments still running on that date ended.

Zyro is a separate, self-serve testing tool. On Shopify you install the app and turn on its app embed; anywhere else you paste one snippet. While a test loads, Zyro hides only the part of the page being tested until its version is ready, with a timeout so your page is never left hidden.

2. Don't Go Back to Spreadsheets

Without a testing tool, some teams try to run tests by hand with Google Tag Manager and spreadsheets. It can work, but it is easy to get wrong and slow to read.

Zyro gives you a visual editor and automatic reporting: click on your own page to change a headline, image or button, and Zyro counts the sales each version makes. On the Growth and Scale plans, bandit tests shift more traffic to the version that sells more while the test runs.

3. Results You Can Read

A test result should tell you what to do next, in plain words.

Zyro reports each test as the chance a version beats your original, using Bayesian statistics, so you can check progress any day. It waits for enough visitors and sales before it pauses a losing version or picks a winner. You can run up to 15 live tests on Starter, 50 on Growth and 250 on Scale.
