A search engine is a program that helps users finds information on the Internet. An automated system sends out a spider to the web and collects site links for its database. When a user types in a keyword or combination of keywords, the spider sorts through the database and ranks the websites in order of relevancy. A search engine is distinguished from a directory and a portal, because its pages are generated by an automated program rather than by human editors. Popular search engines include Ask Jeeves, AltaVista.

A Spider is aprogram that automatically fetches web pages and feeds them to search engines. (It's called a "spider" because it crawls around the web.) Because most web pages contain links to and from other pages, a spider can start almost anywhere. As soon as it recognizes a link to another page, it goes off and fetches it. Large search engines have many spiders working simultaneously. Also known as a crawler.

Search Optimization ia a tactics and techniques that make it easier for spiders to find your page, contributing to higher ranking on a list of search engine results. Basic optimization starts with listing relevant keywords in your metatags and building clear and descriptive words into page copy, title, text hyperlinks, and image file names. It's also important to design your site on a logical link structure and follow standard HTML conventions, avoiding the use of frames, dynamic URLs, Image Maps, and JavaScript for navigation.

Directory ia a compilation of websites reviewed and organized by human editors into useful categories and topics, similar to the organization of the Yellow Pages. Examples of directories are the Google Directory, About.com, and the Open Directory Project.

Portal ia a web page that works as a starting point for a user's session on the Internet. Portals typically include a directory of websites, access to web services and shopping sites, and search functionality powered by a search engine provider. Example of portals is AOL, Netscape, CompuServe, and Earthlink.

Meta Search is a process of searching several databases simultaneously and combining the results.

Dynamic pages exist on the majority of e-commerce sites and many sites which utilize server side technology such as active server pages, php or cgi. A dynamic page in a typical situation may have just one page which could produce hundreds or thousands of variations, depending on parameters passed to a page, which in turn would access a database and collect different information based on the parameters. Search engines have long been unable to handle these, although Google can and will index dynamic pages, it will limit the number of pages. Why the limitation? - The Google bot could crash a web server if it spider every possible occurrence of a dynamic page in a short space of time, for this reason the number of dynamic pages that it will index is limited. This Meta data has physical limits in size and the amount that is recognized/ignored by search engines varies. The recommended maximum size (in characters) for the description tag is 200 characters; for keywords, the maximum would be between 800 and 1000 characters.
