Is it a free boost or a paid boost when it comes to getting orders?

Is the Free Boosting on Seocheckout is so important or not? I usually do Free Boosting regularly but not at the same time. That's why my viewers are not growing nowadays. So, it arises a question in my mind that - does really this free boosting is so important for marketing on Seocheckout??
