Abstract

In this chapter we turn to embedded indexing for the Internet, frequently called Web indexing. We will define Web indexes; describe the structure of entries for Web indexes; present some of the challenges that Web indexers face; and compare Web indexes to search engines. One of the difficulties in defining Web indexes is their relative newness. The first pages were placed on the World Wide Web in 1991 when Tim Berners Lee, its founder, uploaded four files. We are in a period of transition, moving from using well-established forms of writing and communications to others that are still in their infancy. Paramount among these is the Web. For indexers, this is an uncharted voyage where we must jettison firmly established ideas while developing new ones. Where the voyage will end is anyone's guess.

Abstract

<META> tags are used to create meta-information, or information about the information in a Web site. There are many types of <META> tags, but those most relevant to indexing are the description and keyword tags. Description tags provide a short summary of the site contents that are often displayed by search engines when they list search results. Keyword tags are used to define words or phrases that someone using a search engine might use to look for relevant sites. <META> tags are of interest to indexers for two reasons. They provide a means of making your indexing business Web site more visible to those searching the Web for indexing services, and they offer indexers a potential new source of work: writing keyword and description tags for Web site developers and companies with Web sites. <META> tag writing makes good use of an indexer's ability to choose relevant key terms, and the closely related skill of abstracting: conveying the essence of a document in a sentence or two.
