Relax for Windows is a free GPL licensed web server log analyzer. This tool analyzes which search engines, search Mots-clé and referring URLs led visitors to the web site. Frequently updated parser module recognizes hundreds of search engines. HTML reports can be configured to include links to other web based keyword analysis Outils, thus making it easier to try to improve the ranking of web pages in search engines. Relax can natively read log files in RefererLog and Apache combined log formats but it can be configured to read virtually all other formats.
