Directory
definition: acompilation 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 Yahoo!, About.com, and the Open Directory Project. Directories are web page or an entire website dedicated to listing Internet web pages. Directories use human editors to review and categorize sites for acceptance and are compiled manually by user submission. Sites such as UKwizzhave their own directory that accept websites submitted from the general public. The biggest directory is the Open Directory Project, which has members of the public editing the categories. Many other sites now use a Yahoo-like directory including major portal sites. Submission to directories is important because they provide a long-term link to your site from a relevant page - it will increase your link popularity, and, as a minor advantage - you can expect some traffic from them. Each directory listing contains short, descriptive information about the site. Strong directory listings are an excellent way your company can increase its link popularity and its Google PageRank. However, a poorly written listing that is submitted to Yahoo! (and subsequently edited or run with ineffective writing or keyword research) can negatively influence a search marketing campaign.

definition: Every time a new domain name is registered (or an existing one is transferred to a new DNS), the information about the domain and the DNS that hosts it must make its way around the entire internet. This process usually takes around 24 hours, during which time the domain will be inaccessible to users.

Domain
definition: a sub-set of internet addresses. Domains are hierarchical, and lower-level domains often refer to particular web sites within a top-level domain. The most significant part of the address comes at the end - typical top-level domains are .com, .edu, .gov, .org (which sub-divide addresses into areas of use). There are also various geographic top-level domains (e.g. .ru, .ca, .fr, .ua etc.) referring to particular countries. The relevance to search engine terminology is that web sites which have their own domain name (e.g. http://www.webceo.com) will often achieve better positioning than web sites which exist as a sub-directory of another organization's domain

Domain Name
definition: the unique name that identifies an Internet site. Domain Names always have 2 or more parts, separated by dots. The part on the left is the most specific, and the part on the right is the most general. A given machine may have more than one Domain Name but a given Domain Name points to only one machine. Usually, all of the machines on a given Network will have the same thing as the right-hand portion of their Domain Names. It is also possible for a Domain Name to exist but not be connected to an actual machine. This is often done so that a group or business can have an Internet e-mail address without having to establish a real Internet site. In these cases, some real Internet machine must handle the mail on behalf of the listed Domain Name.

Either way it is not great practice to use this type of tactic.

F

Fake Copy Listings
definition: sometimes a malicious company will steal a web page or the entire contents of a web site, re-publish at a different URL and register with one or more search engines. This can cause a loss of traffic from the original site if the search engines position the copy higher in the listings. If you find that someone has stolen your site in this way, write to the company concerned and ask them to remove the stolen content. Also contact the hosting service used by the company, any company that benefits from the theft and any search engine(s) concerned. If the thieves refuse to remove the material or ignore you, obtain legal advice. It is also well worth having printed evidence to support your claim that your copy of the material was there first, and that you have the copyright! See also Mirror Sites.
