Classified advertising is usually text-only and
can consist of as little as the type of item
being sold and a telephone number to call for
more information or a website URL. It can
also have much more detail, such as name to
contact, address to contact or visit, a detailed
description of the product or products ("pants
and sweaters, size 10" as opposed to
"clothing", "red 1996 Pontiac Grand Prix" as opposed to "auto-
mobile"). There are generally no pictures or other graphics within
the advertisement, although sometimes a logo may be used.
Classified advertising is called such because it is generally
grouped within the publication under headings classifying the
product or service being offered (headings such as Accounting,
Automobiles, Clothing, Farm Produce, For Sale, For Rent, etc.)
and is grouped entirely in a distinct section of the periodical, which
makes it distinct from display advertising, which often contains
graphics or other art work and which is more typically distributed
throughout a publication adjacent to editorial content.
A hybrid of the two forms — classified display advertising — may
often be found, in which categorized advertisements with larger
amounts of graphical detail can be found among the text listings of
a classified advertising section in a publication. Business
opportunities often use classifieds to sell their services, usually
employing 1-800 numbers. Classified ads are also among the
tools used by many companies in recruitment for available job
opportunities.
Printed classified ads are typically just a few column lines in length,
and they are often filled with abbreviations to save space and
money.
