The nature of the exhibition is determined by the organizer of the exhibition and can be reflected by the composition of the visitors:
Exhibitions open to the business community are trade-oriented exhibitions, and exhibitions open to the public are consumer-oriented exhibitions.
Content selection
The exhibition is divided into two categories: comprehensive exhibitions and professional exhibitions.
The comprehensive exhibition refers to exhibitions that cover the whole industry or several industries, and is also called horizontal exhibitions, such as industrial exhibitions and light industry exhibitions.
A professional exhibition refers to an exhibition that shows an industry or even a certain product, such as a watch exhibition. One of the outstanding features of professional exhibitions is that seminars and presentations are often held at the same time to introduce new products and technologies.
Scale selection
The exhibition is divided into international, national, regional, local exhibitions, as well as exclusive exhibitions of individual companies.
Scale refers to the size of the area represented by exhibitors and visitors rather than the size of the exhibition venue.
Exhibitions of different sizes have different characteristics and advantages, and should be selected according to the company's own conditions and needs.
Time selection
There are many criteria for the division of exhibitions: regular and irregular.
Regularly four times a year, twice a year, once a year, once every two years, and so on.
Irregular exhibitions are held on an as-needed basis, depending on needs and conditions.
Long-term exhibitions can be three months, half a year, or even permanent, and short-term exhibitions generally do not exceed one month.
In developed countries, professional trade fairs are generally three days.
Site selection
Most of the exhibitions are held in dedicated exhibition venues.
The exhibition venues are divided into indoor venues and outdoor venues.
Indoor venues are often used to display exhibitions of conventional exhibits, such as textile exhibitions and electronic exhibitions.
Outdoor venues are often used to display oversized and overweight exhibits, such as air show and mining equipment exhibition.
Exhibitions held in rotation in several places are called road shows.
