'Relax' is a multi-platform Web server log analyzer written in Perl. It can be used to track which search engines, search keywords, and referring URLs led visitors to the Web site. It can also track down bad links and analyze which keywords to bid for at pay-per-click search engines. The parser module in Relax recognizes several hundred search engines and is capable of extracting the keywords used. Generated HTML reports can be configured to include links to other Web-based keyword analysis tools, making it easier to further improve the ranking of web pages in search engines.
