But, like an exhibit in an art gallery, the real fun beings when people come to visit your site. The fundamental puzzle of the World Wide Web, and the Internet as a whole, is how to find the information. If you can t find stuff, it stands to reason that others will have difficulty finding your stuff too. Millions of documents are available on the WWW, but a comparatively small number of sites offer help in finding particular information. Such sites, known as search engines, consist of a database of indexed web sites.
Search engines rely on the user to enter search parameters.
Rather than beginning with a broad description of the information you want, you begin with a specific word or phrase. In this sense, you are starting at the most detailed level, or at the bottom. Hence, the term bottom-up strategy. This depends on what is registered with the indexing site. All of them.
