Relax is a free specialized web server log analysis tool for referrer information processing. It answers the question: "Which search engines, search keywords and referring URLs led visitors to your site?"
Relax reports tell you quantity of visitor you are getting from the leading search engines, as well as the most popular keywords being used. In version 2.50 Relax recognizes 262 most popular search engines.
Relax generates lists of URLs directing to your pages with a count of the number of times each referring URL was detected.
Relax can be integrated with Etsin to make it easy to use other web based keyword analysis tools. With these tools it's easy to check how different keywords are positioned in different search engines, and get information about related searches.
Relax can help you to track down bad links, measure the success of banner ads and affiliate programs, improve your understanding of your site's clientele, and track down potential intellectual property infringements, as well as to improve site's position in the search engines and to increase traffic.
Relax supports logs in RefererLog, NCSA extended/combined TransferLog, and WebSTAR format. Relax is distributed under GNU General Public License (GPL).
