Our online conference Cloud Data Summit has one distinct disadvantage from an SEO perspective. There is no valid schema tag for online events -- a physical location is required in the Event tag. Google Events refuses to list the event if it is missing a location. So. we are trying to hack Google just like we have hacked Eventbrite. By listing the event in an event center in every major city in the geographies we are targeting. What does this mean? The schema tag has over 100 different locations in it, each with a different Name, Address, City, State, Zip, Country. Oh, and not only that. We did a fair amount of research into other major events which are listed in Google Events (including things like Google I/O) and most of them lack a "complete" Event tag. What I mean by "complete"- we can add lots of info about "performers", the profiles of the performers (with backlinks and lots of keywords), the companies the performers work for (with backlinks and lots of keywords), the people/companies in attendance can be listed out individually (with backlinks and lots of keywords) So we took every opportunity in the Event Schema to take advantage of from a relevant keyword or knowledge graph perspective. The result? The Schema tag is BIG. Like 1500 lines big. And most of the length is due to 100 locations x 8 rows for each. Our research didn't find any events with anything close to this. So I think we are in uncharted territory. Does anyone have experience with huge and very thorough schema tags?
