I am considering a major adjustment to the search-input feature on a website.This search feature appears on many pages.I do have e-commerce operating in Google Analytics. I have glanced at Google Analytics Experiments, but this seems to be more for individual pages and I am looking to measure the performance of a site-wide feature.What is a clean way to A/B test this new search-input feature in Google Analytics, measured by e-commerce conversion rate?
