Every year our company has a user conference with between 300 - 400 attendees. I've just begun giving the event more of a presence on our website. I'm wondering, what is the best way to handle highlights from previous years? Would it be to create an archive (e.g. www.companyname.com/eventname/2015) while constantly updating the main landing page to promote the current event? We also use an event website (cvent) to handle our registrations. So once we have an agenda for the current years event I do a temporary redirect from the main landing page to the registration website. I don't really like this practice and I feel like it might be better to keep all of the info on the main domain. Wondering if anybody has any opinions or feedback on that process as well.

Just looking for best practices or what others have done and have had success with.

So it sounds like you create an archive for the previous years event? Moving the previous years highlights to another page so it can still be accessed?

The url on our registration site changes but we redirect the main landing page to that url temporary. I think ideally the content for the event should be on the main domain and just utilize the third part event site to manage the registrations.

Seems like there are so many ways to do this.
