This is one aspect where an Online Only expo completely beats a traditional expo–hands down.
Let me take the case of a Components Distributor with dozens of principals from all across the globe. In a traditional expo, if a customer wants to know details about a particular component–either the representative of that brand needs to be there at the booth OR you have to say “sorry, we will get back to you.”
But, in an Online Only expo–if you alert your principals well in advance, you could have their team members available LIVE to handle any query that may come for your brand.
Similar advantage is for any firm whose technical team members may be busy at an installation but know the right answers to the question of a customer. You can beam them in.
But, can’t I do both of these in a traditional expo? Yes, you can. But, then the moment you beam them in, you switch to a digital arena.
NUTSHELL: Digital can do what traditional does, and better.
