Trade show technology guru Doug Fox has this advice about using the Internet for your show:
Never force website visitors to open a PDF file to gather information about the show or access a reg form. This shuts out anyone without an Acrobat reader.
Many times the floor plan loads too slowly. Use better software, select a new host or vendor, or create a simpler image that loads quickly.
Do use an online application to help sell booth space in real time. Two of these are a2z (www.a2zshow.com) and eshow 2000 (www.eshow2000.com). But be sure you have a back up plan if something goes wrong with your outside service provider.
Personal schedulers do not work - they are either too confusing or not enough content is loaded into the system. Don't offer them unless you are going to do it right.
Don't require pass words - they are frustrating for your prospects.
Doug says, "use simple, functional technology and create a basic, attractive site that promotes your upcoming meeting, conference or trade show."
