Yes, Spiderline does honor the robot exclusion protocol. Our spiders will not index directories or follow links that have been disallowed in the robots.txt configuration file located on your server. Learn more about Robot Exclusion and robots.txt
Spiderline also honors META tags that designate "noindex" and/or "nofollow".
If you have a robot.txt file or Robot META tags for other robots and want Spiderline to ignore either, you can change this in crawl settings. Default is to honor all robot exculsions.
