There may be lies, damned lies and statistics, but search engine optimization without statistics is like root beer without sassafras (for root beer novices, sassafras is the primary spice in root beer).  Fortunately for PHP-Nuke webmasters, great tools are available for viewing important statistics that can impact site design and choices for search engine optimization.  Unfortunately, these tools are included in the standard PHP-Nuke distribution.  MatyScripts' MS-Analysis provides many functions that can be used with nukeSEO to enhance SEO efforts, including powerful reporting for referrals, webcrawlers, search engines and search words used to find your site.
