The Internet is like a library without a card catalog, just as a bookstore is a library with a cash register. Card catalogs are derived from information found on the title page of a book. The library card contains information about the author and title, and librarians come up with subject information, so a book can be found by author, title, and subject. The Internet has few authors by name, sites without titles, and must eventually rely upon other web sites to link to a web page or upon search engines reading and building an index of the information on a web page. Most people rely upon search engines to find and rank web pages by a search of keywords, which approach thousands of entries. Web page authors must now register their web pages with the various search engines, which in turn use their "spiders" or "worms" to read and extract the information in building an index. AltaVista crawler is called "Scooter" Every time someone submits an URL to be added to AltaVista's index, "Scooter" goes to that URL, reads the entire web sites, extracts the appropriate information, and adds it to the AltaVista index. AltaVista and Yahoo normally accomplish this in a few days. On the other hand Excite and Magellan take from two to four weeks! Titles to web pages are NOT seen on the web pages. With Netscape Navigator they appear at the very top of the browser page in white with a blue background called the "Title Bar". The same is true of Microsoft Internet Explorer, except they shorten the title and add the words -- "Microsoft Internet Explorer". The main reason for having a good subject title is most search engines give the title the greatest weight in ranking web pages. The second reason is this title is almost always bolded and underscored in displaying the search results. |
