A podcast usually lives across several platforms at once, Spotify, Apple Podcasts, YouTube, none of which is really a home base you control. A dedicated site solves a specific problem those platforms don't: somewhere a potential sponsor, guest, or press contact can go to see what the show is about, who's behind it, and where to actually listen, without being just another show in someone else's catalog.
Describing your show to Nova, for example "a website for an interview-style podcast about independent film, with episode links, host bios, and a way for guests to reach out," produces a site structured around that description, with a live preview before you publish. Because the copy reflects your actual show and format rather than a generic "podcast site" template, the about section tends to start closer to something you'd send a prospective guest or sponsor.
Worth being direct about: Nova builds the site itself, but it doesn't host your audio or generate an RSS feed, you'll still host episodes on a podcast hosting platform and link out to it, or to each streaming platform, from the site. If you're pitching sponsors, most shows also put together a separate media kit with download numbers, which lives outside the website itself.
Depending on what your podcast host supports for embeds, you can typically add that kind of player to a page Nova builds; check your host's current embed options when building the page.
No, Nova builds the website; audio hosting and RSS distribution stay with a dedicated podcast hosting platform that you link to from the site.
Yes, describe that you want a guest pitch or contact section, and Nova will include it as part of the site structure.
