We have a fairly large site which does a cookie-based 302 redirect to the the specific city page if someone types in the Home page URL. Though if the cookie is not available (first time user) it goes to the Homepage and asks user to select the city as our services are city based. Everything is working fine with this setup.
Though our tech team now wants to display the contents of city page on homepage URL itself if the cookie is available without 302 redirecting to new URL. Though no cookie scenario remains unchanged.
Please confirm possible issues in rankings with this change as based upon city present in the cookie homepage will display different content.
