Classified advertising

Classified advertising is a form of advertising which is particularly common in newspapers, online and other periodicals which may be sold or distributed free of charge. Classified advertisements are much cheaper than larger display advertisements used by businesses, although display advertising is more widespread.

Advertisements in a newspaper are typically short, as they are charged for by the line, and are one newspaper column wide.

Publications printing news or other information often have sections of classified advertisements; there are also publications that contain only advertisements. The advertisements are grouped into categories or classes such as "for sale—telephones", "wanted—kitchen appliances", and "services—plumbing", hence the term "classified". Classified ads generally fall into two types: individuals advertising sales of their personal goods, and advertisements by local businesses. Some businesses use classified ads to hire new employees.

One issue with newspaper classified advertising are that it doesn't allow images, even though display ads, which do allow images, can be found in the classified section.

In recent years the term "classified advertising" or "classified ads" has expanded from merely the sense of print advertisements in periodicals to include similar types of advertising on computer services, radio, and even television, particularly cable television but occasionally broadcast television as well, with the latter occurring typically very early in the morning hours.

Like most forms of printed media, the classified ad has found its way to the Internet, as newspapers have taken their classified ads online and new groups have discovered the benefits of classified advertising.

Internet classified ads do not typically use per-line pricing models, so they tend to be longer. They are also searchable, unlike printed material, tend to be local, and may foster a greater sense of urgency as a result of their daily structure and wider scope for audiences. Because of their self-regulatory nature and low cost structures, some companies offer free classifieds internationally. Other companies focus mainly on their local hometown region, while others blanket urban areas by using postal codes. Craigslist.org was one of the first online classified sites, and has grown to become the largest classified source, bringing in over 14 million unique visitors a month according to comScore Media Metrix. A growing number of sites and companies have begun to provide specialized classified marketplaces online, catering to niche market products and services, such include boats, pianos, pets, and adult services, amongst others. In many cases, these specialized services provide better and more targeted search capabilities than general search engines or general classified services can provide.
