How Does Google Handle HSTS 307 Redirects
https://www.youtube.comJohn explains that 307 Redirects are not a true redirect as only browsers are capable of seeing a 307 and it doesn’t mean anything to Googlebot.
When Googlebot crawls a HTTP page with HSTS, it will not be redirected to the HTTPS version as a browser would. That said if you have an HTTP > HTTPS redirect there then Gogole bot will follow that.
