LinkAlarm is an online tool for checking links on web sites.
It is a commercial service, but it can scan up to 100 pages for free during a 14-days trial period.
The tool can be adjusted to the user’s needs. It automatically checks links on a web site once a week or once a month, for example.
The user has to register, enter the web site for checking, and in a few minutes LinkAlarm sends the detailed report to the user e-mail that indicates the number of checked internal and external links, and what links contain errors.
