A WebBot is a web-based robot program capable of performing certain automatic operations. FrontPage WebBots are used by Microsoft to invoke many of the interactive features built into FrontPage. Those features are added to your site through the FrontPage Editor.
Some, such as "Include" and "Substitution" allow elements of your site to be entered once and included in any or all of the pages by inserting the Bot component referencing that element (e.g., a logo or navigation bar). Changes made to the "master" element are made automatically to any page containing the referencing Bot.
Other Bots, such as Search, Table of Contents, and Timestamp, control dynamic browse-time features. These Bots work behind the scenes to make it easy to keep your site current and consistent.
