About Business Directories

A Business directory or business directory is a website or printed listing of information which lists all businesses within some category. Businesses can be categorized by business, location, activity, or size. Business may be compiled either manually or through an automated online search software. Online yellow pages are a type of business directory, as is the traditional phone book.

The details provided in a business directory will vary. They may include the business name, addresses, telephone numbers, location, type of service or products the business provides, number of employees, the service region and any professional associations. Some directories include a section for user reviews, comments, and feedback. Business directories in the past would take a printed format but have recently been upgraded to websites due to the advent of the internet.

Many business directories offer complimentary listings in addition to the premium options. There are many business directories and some of these have moved over to the internet and away from printed format. Whilst not being search engines, business directories often have a search facility.
