Google Secrets Revealed

A patent application from the Mountain View-based search engine company gives some insight into its PageRank technology. If you're a legitimate site owner, you'll want to register your domain for more than one year. Otherwise, the Google PageRank algorithm may rate your site lower than you may deserve.

There are several factors that may affect the quality of the results generated by a search engine. For example, some web site producers use spamming techniques to artificially inflate their rank. Also, "stale" documents (i.e., those documents that have not been updated for a period of time and, thus, contain stale data) may be ranked higher than "fresher" documents (i.e., those documents that have been more recently updated and, thus, contain more recent data). In some particular contexts, the higher ranking stale documents degrade the search results. Interested parties should visit here.
