With search engines directing a substantial fraction of the traffic to
many Web sites, the ranking of one's pages and their standing compared
to offerings of others is of acute interest to many site operators.
This Perl utility allows you to query Google's ranking of any page on
the Web, either from the command line or via a Web query form
submitted to a CGI application on a Web server. In addition, the
utility can display a graphical “page rank meter” which
shows visitors the instantaneous ranking of pages on your site.
Security features allow restricting access to the Web query facility
to keep your site from being submerged by requests by third parties.
Note: As of April 2016, Google has discontinued their public
PageRank query facility. This code will no longer work and is
obsolete.
