Google Optimize 360 vs Optimize: What You Need to Know

Google Optimize is a free testing tool that natively integrates with Google Analytics. "Optimize" allows you to easily run tests on your website, starting from simple A/B tests to slightly more complex multivariates.

Optimize 360 on the other hand is the paid (& supercharged!) version of Optimize Free. Offering up expanded testing features and even personalization capabilities -- Optimize 360 is a part of the Google Marketing Platform.

The Benefits of Google Optimize 360 vs Optimize

1. Enterprise Scalability

Optimize is suited for smaller businesses that will only conduct testing on a small scale (the limitation being you can run up to 5 experiments at the same time), whereas Optimize 360 is suited for enterprise level organizations where you can run more than 100 experiments at a time.

That means frequent testing of more tailored and sophisticated testing needs.

2. Additional Experiment Objectives

An objective in Optimize is essentially what you want to track as a measure of success. In Optimize, you can set up to 3 objectives for measuring success by.

For example, if you’re A/B testing a call-to-action that’s expected to impact conversion rates for 5 different Google Analytics goal completion (or "conversion") types, Optimize Free allows testing just 3 at a time. For comparison, Optimize 360 allows for running up to 10 objective at a time. More objectives = more ways to measure success.

3. More Complex Multivariate Tests

With Optimize 360, you can run multivariate test variants of two or more elements simultaneously to see which combination creates the best outcome.

  • Instead of showing which page variant is most effective (as in an A/B test), MVT identifies the most effective variant of each element as well as analyzing the interactions between those elements.
  • If you’re testing large scale changes, Optimize 360 provides up to 36 combinations at a time (vs just 16 with Optimize Free!)

4. Enterprise-Level Service & Support

Optimize 360 is covered by Google's SLA, which means that the product is reliable at the enterprise level. If you are using a GA360 reseller, like Seer as well. For more advanced testing, this additional support gives Optimize 360 a leg up on the free version.

5. Comprehensive Audience Targeting

Optimize 360 has one massively powerful function that is not available in Optimize Free -- the ability to target experiments through audience segmentation in other platforms.
