Lets look at some settiings, so you could enter a list of websites to crawl for expired domains on, or you can enter a search query say you're looking to form a pbn to boost your money site, that's about horse riding or something you could put horse riding down there and then it'll search, Google for horse riding and then crawl all the domains that Google brings back to you. Then we've got endless crawl and you basically you put in a few seed websites and then it will just crawl endlessly from those websites. So it will take all the domains off those websites. First they'll check whether they're expired or not. If they're not expired, then it'll start crawling them and then it will crawl the ones it finds from them and so on so on and so on. It will just keep going ok.
