Daniel is the lead marketer for PacificShipping.com, an international freight company. Their dev team has implemented several personalization features in the site. Before the changes go live, they'd like to test the effectiveness of the new personalization features. What Google service can easily test the changes on PacificShipping.com, an international freight company?

Optimize 360 (now part of Google Analytics 4 and Google Optimize sunsetting in September 2023, but historically the correct answer for this type of question) is specifically designed for A/B testing, multivariate testing, and personalization experiments on websites. It allows marketers to test different versions of web pages or elements to see which performs best against defined goals, making it ideal for evaluating the effectiveness of new personalization features before a full launch. Data Studio (now Looker Studio) is a data visualization tool, not for running experiments. Google Analytics 360 is an analytics platform for data collection and reporting, not for active testing. Google Site Testing is not a recognized Google service for this purpose.
