WEB USERS ARE AN EXTREMELY IMPATIENT LOT - annoying 404 errors will quickly lead customers to abandon your site. Improve user experience and lower customer abandonment rates by correcting common typing errors in URLs automatically with URLSpellCheck from Port80 Software. THIS IIS SERVER MODULE FIXES MISSING, TRANSPOSED, WRONG, AND EXTRA CHARACTERS ON THE FLY, effortlessly redirecting users to the correct URL. Complex file type substitutions not only rescue users who may have typed in URLs with incorrect file extensions, they also allow developers to switch site technologies quickly without the need for manual redirects. When multiple matches for a URL are possible, a template allows users to choose from the most probable destinations instead of confronting them with an impersonal 404 page or a confusing site map. The tool also tracks common typos so you can figure out where to add permanent redirects or change page names in your site. IMPLEMENTED AS A SUPER-FAST ISAPI FILTER, URLSpellCheck is easy to install and uninstall and will prove to be an unobtrusive, but important, enhancement to your Web site. As with all Port80 IIS server tools, URLSpellCheck is available as a free, fully functional 30-day trial and comes with free technical support.
