D
Directory: A site containing links to other sites which are organized into various categories. Examples of directories are Yahoo, Open Directory, LookSmart, etc.
Domain, Top Level Domain (TLD): Hierarchical scheme for indicating logical and sometimes geographical venue of a web-page from the network. In the US, common domains are .edu (education), .gov (government agency), .net (network related), .com (commercial), .org (nonprofit and research organizations). Outside the US, domains indicate country: ca (Canada), uk (United Kingdom), au (Australia), jp (Japan), fr (France), etc. Neither of these lists is exhaustive.
Domain Name, Domain Name Server (DNS) Entry: Any of these terms refers to the initial part of a URL, down to the first /, where the domain and name of the host or server computer are listed (most often in reversed order, name first, then domain). The domain name gives you who "published" a page, made it public by putting it on the Web. A domain name is translated in huge tables standardized across the Internet into a numeric IP address unique the host computer sought. These tables are maintained on computers called "Domain Name Servers." Whenever you ask the browser to find a URL, the browser must consult the table on the domain name server that particular computer is networked to consult. "Domain Name Server entry" frequently appears a browser error message when you try to enter a URL. If this lookup fails for any reason, the "lacks DNS entry" error occurs. The most common remedy is simply to try the URL again, when the domain name server is less busy, and it will find the entry (the corresponding numeric IP address).
Doorway Page (AKA Entry, Bridge or Gateway Page): A page which has been specially created in order to get a high ranking in the search engines. Also called gateway page, bridge page, entry page etc. Stay away from this type of search engine optimization techniques - these are considered Black Hat methods and will get you banned in the search engines.
Dynamic Content: Information in web pages which changes automatically, based on database or user information. Search engines will index dynamic content in the same way as static content unless the URL includes a ? mark. However, if the URL does include a ? mark, many search engines will ignore the URL.
E
Eric Ward: Eric Ward offers content publicity & link building strategies since 1994. He helped Jeff Bezos out with Amazon.com. See also URLWire.
Extension or File Extension: In Windows, DOS and some other operating systems, one or several letters at the end of a filename. Filename extensions usually follow a period (dot) and indicate the type of file. For example, this.txt denotes a plain text file, that.htm or that.html denotes an HTML file. Some common image extensions are picture.jpg or picture.jpeg or picture.bmp or picture.gif
F
Favorites: In the Internet Explorer browser, a means to get back to a URL you like, similar to Netscape's Bookmarks.
Field Searching: Ability to limit a search by requiring word or phrase to appear in a specific field of documents (e.g., title, url, link).
Frames: An HTML technique allowing web site designers to display two or more pages in the same browser window. Many search engines do not index framed web pages properly - they only index the text present in the NOFRAMES tag. Unless a web page which uses frames contains relevant content in the NOFRAMES tag, it is unlikely to get a high ranking in those search engines. To go BACK in a frame, position the cursor in the frame an press the right mouse button, and select "Back in frame" (or Forward). You can adjust frame dimensions by positioning the cursor over the border between frames and dragging the border up/down or right/left holding the mouse button down over the border.
Freshness: How up-to-date a search engine database is, based primarily on how often itsspiders re-circulate around the Web and update their copies of the web pages they hold, and discover new ones. Also determined by how quickly they integrate new sites that web authors send to them. Two weeks is about as good as most search engines do, but some update certain selected web sites more frequently.
FTP: File Transfer Protocol. Ability to transfer rapidly entire files from one computer to another, intact for viewing or other purposes.
Fuzzy AND: In ranking of results, documents with all terms (Boolean AND) are ranked first, followed by documents containing any terms (Boolean OR) are retrieved. The farther down, the fewer the terms, although at least one should always be present.
G
Google: The World's largest search engine.
