SEOENGBot™ is an automated computer program which visits Websites and takes a snapshot of the content on those Websites. Commonly called a "Robot", this computer program is actually run across many servers, and can support crawling millions of Websites per day.
If you have access to your Website logs, and SEO Engine™ has crawled your Website, you will see a signature similar to this:
SEOENGBot™ adheres to the Robots.txt standard, and will throttle requests as necessary to prevent the triggering of bandwidth filters on the Websites that it visits.
You can always see the status of SEO Engine™ by visiting the Status Screen either from a Website Dashboard, or a Webpage Scoresheet.
