Wow, there's a real pattern emerging because I just checked serpfox as well and the interface of all these 3 services are clearly powering via the same platform and software. Does anyone know what the parent program , service or software for all of them is and ...following on from that,do they have a reseller program because clearly there is either a reseller situation happening or else the software originator is housing the frontend signups on several different domains. I don't really care as I just want to get to the bottom of it so I can make an informed decision instead of wasting more time and money on different serp trackers.
