Best way to show different homepages based on whether the user has visited our other site?

Hi! We are looking to show a different homepage based on whether the user has visited our other site. I wanted to double check the way I am currently doing it and see if anyone had a better way. Currently, I am setting a cookie in Google Tag Manager based on whether the user has visited our other site. In Webflow, I am checking the cookie and if it is set I am using JavaScript to redirect the user. If anyone had any thoughts or better way of doing things, it would be super helpful!
