1, i am sorry here is no such a function in TrafficBotPro. But right now, you can set the Hit to be 100 per day, then software will only run 100 times, then will auto stop running.
2,
Interval time to next page: the pause time to continue to search on next page in Google, Yahoo, Bing........
eg: if you want to search your website on Google, and here are 5 search reuslts. When bot finished searching your website at 1st page, then it will pause 2-5 seconds, then will continue to do the search on 2nd page.....
Search interval time: the pause time to re launch a new debug window to run.
3, Here is a tutorial for this software, probably you can have a look:
