Internet Searching, Search Engines, and Search-Engine Optimization
Directories, search engines, and guides provide a means of finding information on a given topic by searching through their databases for
keywords. Each service indexes and organizes data from the web according to its own plan, and results can vary widely from one service to another. The details of these plans are kept confidential to prevent webmasters from search-engine spamming -- creating content for no other reason than to take advantage of searchengines peculiarities.
Webmasters, on the other hand, try to tailor their content to be well-indexed. They use common keywords and keyword combinations, repition,
emphasis, HTML "meta" tags, and whatever else they can think of to improve their search-engine rankings. this process is known as "Search Engine Optimization" or SEO. The line between SEO and spamming is ill-defined, but certain practices are clearly frowned upon.
When using search functions, the best approach is to try several products, and use the one that best fits your needs. Searching for the phrase "search engines" will often turn up a new ( or at least unknown ) search site.
Search Engine Watch provides
detailed information on various services, as well as informative articles on search technology in general.
Huge Search Engines - Index the most comprehensive data, but of necessity rely upon artificial intelligence (AI) to establish relevance. Many feel that smaller directories provide better results, especially on very specific topics which may have keywords in common with other disciplines.
Search Engine Size, (number of pages indexed) alone is not a good measure of a service's effectiveness, but it is a specific basis for comparison.

MSN Search -- Microsoft is a late-comer to the search world, having used Yahoo!-powered MSN Search until quite recently. Although I am nof fan of Microsoft generally, MSN search is hard to beat. Their new crawler is everywhere, providing the most up-to-date results of the major engines. Webmasters cannot ignore the traffic that MSN Search generates.
- Google: - Uses PageRank™ algorithm to produce very relevant results. Google doesn't mix paid advertising with standard results, which lends a sense of objectivity to their rankings. The Google interface is deceptively simple, but a little persistence will turn up a variety of features, services, specialized searches, and help.
Since Google is by far the most popular search on the web (as of this update, June 2005) there is a great deal of speculation about it's current ranking algorithm.
- AOL Search -- Yet another "Powered by Google" engine. Lags behind even Googlebot's sluggish indexing.
- Teoma -- Uses Subject-Specific Popularity™ to assign greater weight to links within a community of subject-related sites in ranking sites. Teoma indexes over 2 billion pages and is the primary supplier of Links to the Ask Jeeves search engine.

with a difference: editing is accomplished by volunteer editors. New submissions are included in a timely fashion in some categories - others may take six months (!). Unfortunately, Google is the most-used search engine on the web, and they rely heavily upon ODP. You need to be listed here.
As with any directory, the categories in the ODP tend to be somewhat arbitrary. In some cases your page will be dumped into an undifferentiated catch-all. At other times you will be required to drill down with hair-splitting exactitude to find the "right" submission category. In the end, an editor who doesn't really understand the intended use of your site may put your page in a weird category. There is an appeals process, but it's pretty cumbersome, too. Familiarizing yourself with the ODP categories that apply to your site is time well spent.

- Now an Amazon.com company, Alexa's search is "Powered by Google" and includes some interesting additional features.
Input from users who download the Alexa Toolbar is incorporated into Alexa's database to provide additional information such as related links, site traffic, and link popularity. The Alexa Toolbar is very similar to the Google Toolbar, and I wouldn't be surprised if it was a licensed version of the same. It has the very similar features, including a page rank indicator (indispensible for webmasters' Search Engine Optimization ) an excellent and inobtrusive pop-up blocker and more. In the interest of full-disclosure, I must note that any Amazon.com links that appear in your search will have our amazon associate ID embedded in them (we get a small commision if you purchase something).
