Google Analytics is a powerful tool, it can even be used for website UX!
As UX Design said, "UX and conversions are highly intertwined concepts. Even the best Digital Marketing campaigns fail to get you leads if the landing page UX is not up to the mark."
Make sure that you track the audience for things like language accessibility and what device your site is being accessed on. Pageviews can help you with website navigation and bounce rate will tell you where to improve.
