What is Google Optimize?

Google Optimize logo

Formerly known as Google Website Optimizer, Google Optimize is Googles very own testing tool that uses web analytics, testing and conversion rate optimisation techniques to help those who run a website, such as marketers or business owners, increase visitor conversion rates and overall visitor satisfaction.

Google Optimize is a freemium service, which means many aspects of the tool can be used for free, however some additional tools and functionalities within the tool are an additional cost.

Why do I need an alternative?

Because, as of 30th September 2023, Google announced that they will be sunsetting Google Optimize,.

So, we will no longer be able to use the service.

Why is Google sunsetting Google Optimize?

Google has chosen to sunset Google Optimize because they want to focus on investing in more robust third-party A/B testing integrations for Google Analytics 4.

They also stated that they will be supporting more A/B testing integrations in Google Analytics 4 going forward.

When will Google sunset Google Optimize?

As mentioned above, 30th September 2023 will be the date that Google is going to be sunsetting the tool.

Google have advised that all users ensure they have downloaded their historical data from within the Optimize user interface before 30th September 2023 to ensure they don’t risk losing any data, as you will not be able to access your experience inference results or your historical Google Analytics raw data after the sunset date.
