PageRank » Return to site
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.

Pay for Performance » Return to site
Payment structure where affiliated sales workers are paid commission for getting consumers to perform certain actions.

Publishers publishing contextual ads are typically paid per ad click. Affiliate marketing programs pay affiliates for conversions - leads, downloads, or sales.

Penalty » Return to site
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.

Precision » Return to site
The ability of a search engine to list results that satisfy the query, usually measured in percentage. (if 20 of the 50 results match the query the precision is 40%)

Search spam and the complexity of language challenge the precision of search engines.

Profit Elasticity » Return to site
A measure of the profit potential of different economic conditions based on adjusting price, supply, or other variables to create a different profit potential where the supply and demand curves cross.
Proximity » Return to site
A measure of how close words are to one another.

A page which has words near one another may be deemed to be more likely to satisfy a search query containing both terms. If keyword phrases are repeated an excessive number of times, and the proximity is close on all the occurrences of both words it may also be a sign of unnatural (and thus potentially low quality) content.
