After publishing your site to public internet (via static ip, ddns, port forwarding etc.), you can pick a domain name (if not have) for it using services like Freenom.
Further more, you can also add some SEO tweaks to your page via editing the template (for HFS) front page (the [] section), consult the Internet and HFS wiki for more help.
Also, you can populate, or simply monitor your site status by registering an account at Google/Bing webmaster tools and add details of your site.
Don't forget to spread the words on social medias!
Wish that helps~
