Welcome to the Q&A Forum

Alright, so let's say we've got an event coming up. The URL is website.com/event. On that page, you can access very small pages with small amounts of information, like website.com/event/register, website.com/event/hotel-info, and website.com/event/schedule. These originally came up as having missing meta descriptions, and I was thinking a rel=canonical might be the best approach, but I'm not sure. What do you think? Is there a better approach? Should I have just added a meta description and moved on?
