Using the time-varying behavior of links to (and/or from) a document, search engine 125 may score the document accordingly. For example, a downward trend in the number or rate of new links (e.g., based on a comparison of the number or rate of new links in a recent time period versus an older time period) over time could signal to search engine 125 that a document is stale, in which case search engine 125 may decrease the document's score. Conversely, an upward trend may signal a "fresh" document (e.g., a document whose content is fresh--recently created or updated) that might be considered more relevant, depending on the particular situation and implementation.

Link Buyers beware. You cant go on increasing your links artificialy forever.
