Scalable Linkbot Pro investigates link rot, targets URLs

A wise Web site manager triple-checks links and other trouble spots, even if the site's authoring program has its own maintenance features.

''Link rot can result from external as well as internal file changes or movements. Linkbot Pro 4.0 from Tetranet Software Inc. of Ottawa troubleshoots link rot by crawling through a site and reporting conditions down to the desired level of detail. Its primary targets are the uniform resource locators that connect Web pages to each other and to e-mail, files and applets.

''Linkbot Pro examines both simple and complex links, including those in JavaScript and Hypertext Markup Language 4.0 code. To fix problems shown in Linkbot's report, a user clicks the bad URL and edits the source code in any HTML editor.

Potent package

''Tetranet claims the package is scalable enough to examine sites with hundreds of thousands of pages and those hidden within complex Internet infrastructures.

''Linkbot reports under the headings What's New, What's Old and What's Slow. It has more diagnostic options than midrange authoring programs'for example, graphical reports of site quality over time.

''The $295 package requires Microsoft Windows 9x or Windows NT, 16M of RAM and a 32-bit Internet connection. Download a 15-day trial version of Linkbot at www.tetranetsoftware.com/download/text.htm.

''Site managers can turn to the Web itself. Visit www.websitegarage.com for a free preview checkup by several in-depth online services, each of which costs $9.99 per month.

''Another free Web service, NetMechanic at www.netmechanic.com, e-mails back a report about invalid links, missing graphics, HTML problems and spelling errors.
