Hello weemo, :)
Ranking is a complex operation with many factors, this software will definitely help you with the visits component of ranking. The software can provide visitors to your site, continuously, as real visitors, scrolling, and clicking etc.... You can also set the TIME of the visit to your site which will improve your bounce rate and help with ranking. You can use a VPN, but not at all necessary, nothing to be scared of, but you should ALWAYS be using a VPN anyway, the world is not safe for your business website information. If you have any more questions, you can leave me a message and I will do my best to help you including if you want to get a discount on the software and any set up questions you may have.
Thanks for your question!
Sonny :)
