Page history vs Keywords in URL

Could you please help?

We have a website for a popular online course which was mainly sold from Facebook and Instagram. Now we would like to optimize it for google as well. Unfortunately, it does not have our keywords in the url name.

Are the visits accumulated so far on this page worth more in google's eyes than optimizing for keywords? In other words, should we set up a new page in wordpress with keywords in the URL and move the course there, or is it better to just work on the existing page without changing its url name, but by doing so also keeping the page history (if it's worth anything)?
