Temporarily or permanently becoming de-indexed from a directory or search engine. De-indexing may be due to any of the following: Pages on new websites (or sites with limited link authority relative to their size) may be temporarily de-indexed until the search engine does a deep spidering and re-cache of the web. During some updates search engines readjust crawl priorities. You need a significant number of high quality links to get a large website well indexed and keep it well indexed. Duplicate content filters, inbound and outbound link quality, or other information quality related issues may also relate to re-adjusted crawl priorities. Pages which have changed location and are not properly redirected, or pages which are down when a search engine tries to crawl them may be temporarily de-indexed. Search Spam: If a website tripped an automatic spam filter it may return to the search index anywhere from a few days to a few months after the problem has been fixed. If a website is editorially removed by a human you may need to contact the search engine directly to request reinclusion.

A link which is no longer functional.
Most large high quality websites have at least a few dead links in them, but the ratio of good links to dead links can be seen as a sign of information quality.
An internet link which doesn't lead to a page or site, probably because the server is down or the page has moved or no longer exists. Most search engines have techniques for removing such pages from their listings automatically, but as the internet continues to increase in size, it becomes more and more difficult for a search engine to check all the pages in the index regularly. Reporting of dead links helps to keep the indexes clean and accurate, and this can usually be done by submitting the dead link to the search engine.

High quality directories typically prefer the description describes what the site is about rather than something that is overtly promotional in nature. Search engines typically use a description from a trusted directory (such as DMOZ or the Yahoo! Directory) for homepages of sites listed in those directories use the page meta description (especially if it is relevant to the search query and has the words from the search query in it) attempt to extract a description from the page content which is relevant for the particular search query and ranking page (this is called a snippet) or some combination of the above
Descriptive text associated with a web page and displayed, usually with the page title and URL, when the page appears in a list of pages generated by a search engine or directory as a result of a query.

A categorized catalog of websites, typically manually organized by topical editorial experts. Some directories cater to specific niche topics, while others are more comprehensive in nature. Major search engines likely place significant weight on links from DMOZ and the Yahoo! Directory. Smaller and less established general directories likely pull less weight. If a directory does not exercise editorial control over listings search engines will not be likely to trust their links at all.
Human editors group websites into categories and provide site descriptions or edit descriptions that are submitted to them. With a directory, picking the right category and composing a description rich in key phrases will ensure maximum visibility. Contrast this with a search engine, which is unedited and concerned primarily with the HTML of a site's constituent pages.
A server or a collection of servers dedicated to indexing internet web pages and returning lists of pages which match particular queries. Directories (also known as Indexes) are normally compiled manually, by user submission and often involve an editorial selection and/or categorization process.

Scheme used for logical or location organization of the web. Many people also use the word domain to refer to a specific website.
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. .ar, .ca, .fr, .ro 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.nativetongues.com) will often achieve better positioning than web sites which exist as a sub-directory of another organisation's domain (e.g. http://ourworld.compuserve.com/homepages/tijana/).
