Very nice. Very useful too. I saw another site similar to yours, but I believe yours is more interesting. Is there a reason why your sectors (categories) are not in alphabetical order? https://tradeshowz.com/trade-shows-by-industry You may want to consider making a list in addition to what you have there. Something like: Advertising & Marketing Automotive Computer Design Etc. Etc.
Thank you for your nice reviews. About sectors, they are not in alphabetical order because, they are ordered in number of events.
