A logarithmic scale based on link equity which estimates the importance of web documents. Since PageRank is widely bartered Google's relevancy algorithms had to move away from relying on PageRank and place more emphasis on trusted links via algorithms such as TrustRank. The PageRank formula is: PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn)) PR= PageRank d= dampening factor (~0.85) c = number of links on the page PR(T1)/C(T1) = PageRank of page 1 divided by the total number of links on page 1, (transferred PageRank) In text: for any given page A the PageRank PR(A) is equal to the sum of the parsed partial PageRank given from each page pointing at it multiplied by the dampening factor plus one minus the dampening factor.

Google uses a weighted form of link popularity called PageRankÂ. Not all links are created equal. Google differentiates a link from an important site (such as CNN.com) as being better than a link from Jim-Bob's personal home page. The Google Toolbar (which is a free download from http://toolbar.google.com) has a PageRank meter built into it, to see which web pages are considered important by Google and which aren't. PageRank scoring ranges from 0 to 10, 10 being the best. PageRank scores get exponentially harder to achieve the closer to 10 they are. For example, increasing your own homepage's PageRank from a 2 to 3 is easy with not a lot of additional links, jumping from a 7 to an 8 is very difficult to achieve. The higher the PageRank of the page that's linking to you, the more your site's PageRank will benefit. The better your PageRank, the better you'll do in Google, all else being equal.

The process of analyzing input to determine its grammatical structure with respect to formal grammar. A parser is a computer program that carries out this task. Parsing transforms input text into a data structure, usually a tree, which is suitable for later processing and which captures the implied hierarchy of the input. Generally, parsers operate in two stages, first identifying the meaningful tokens in the input and then building a parse tree from those tokens.

Search engines prevent some websites suspected of spamming from ranking highly in the results by banning or penalizing them. These penalties may be automated algorithmically or manually applied. If a site is penalized algorithmically the site may start ranking again after a certain period of time after the reason for being penalized is fixed. If a site is penalized manually the penalty may last an exceptionally long time or require contacting the search engine with a reinclusion request to remedy. Some sites are also filtered for various reasons. See also: Google -30 rank penalty - an example of a penalty
