A landing page for a conference, workshop, or webinar has a narrower job than most business sites: convince someone this specific event is worth their time and get them to register, ideally before you start actively promoting it. That's a different page than an MVP landing page built to validate a new idea, which is testing interest in a product, or a crowdfunding pre-launch page building an email list for a funded campaign. An event page already has a fixed date and a defined agenda, its job is registration, not validation or fundraising.
Describing your event to Nova, for example "a landing page for a one-day marketing workshop, with the agenda, speaker bios, and a registration link," produces a page structured around that, complete with feature previews along the way and a live preview once it's built, ready to publish to a free getnova.pro subdomain without ever needing an account first. Because the agenda and speaker sections reflect your actual event rather than a generic "join us" template, the draft starts closer to something that answers the two questions most people actually have before registering: what will I get out of this, and who's running it.
One limitation worth planning for: Nova builds the page itself, but it isn't event registration or ticketing software, so a "register" button on the page still needs to connect to an actual tool, something like Eventbrite, a simple form linked to your email service, or a payment link if the event is paid, for collecting and managing sign-ups. Most event organizers already use one of those tools regardless of what builds the page around it, so this isn't a new step, just one that happens outside Nova.
It can, as long as the core details, date, format, and what attendees will get out of it, are set; you can update the agenda or speaker list as those details firm up.
No, you'd connect a registration or ticketing tool and link to it from the page; Nova builds the page and the information on it, not the sign-up processing behind it.
Yes, you can update the date, agenda, and speakers for each occurrence rather than building a new page every time.
Describe your event to Nova and see the registration page before you start promoting it.
