You probably want to add the Onion-Location header to the clearnet site so Tor Browser can automatically inform the visitor about it: https://community.torproject.org/onion-services/advanced/oni...

What is the benefit of building the same website twice with different hostnames instead of using relative links to content on the same domain?

Besides accessing your page are random people able to use your server as an exit node? Am I thinking the right thing... I met someone in Switzerland that was hosting anonymous exit nodes to some anonymous network and he said that it was a pain having to explain what was happening to the police.

Thanks for sharing! Happy to get feedback :)
