Welcome to the Q&A Forum

Hi there beritv, could you share some more information about this question? It would be good to get confirmation on a few points: What is the main purpose of the event page? I'm picturing a listings page which frequently changes because events are added and taken away, and includes either scroll loading or pagination for the latter results but someone I've chatted with about this thinks it could also be a static page which has changing details for a specific event. Which pages are we talking about archiving? Expired individual event pages? What is the nature of the archiving we're discussing? How would it work? I can see that Martin is asking whether it's a separate site (in which case I wouldn't recommend it particularly from an SEO perspective because if it's indexable it might start to compete with your live site). The person I've chatted with has asked whether this is a process of deindexing or taking offline the pages. If you could clarify that, it would help a lot. Are your IT dept. recommending this as an information store or are they citing SEO reasons? If the concern is having lots of out-of-date event pages there may be file management and UX considerations to take into account - if having lots of defunct event pages makes your CMS unmanageable then it seems reasonable to have a way of refiling them there but that doesn't necessarily have to be reflected in the live site. On the other hand, are you seeing users landing on event pages for which the event has passed? If so, that's not fantastic UX and is likely to lead to them leaving your site immediately and clicking on another result which would have an SEO impact because it's sending consistent messages to Google that you're not fulfilling the search intent.
