I see a few people selling these on BHW. Tried to ask the sellers these questions and no one answers so here goes: _Do you have to continually add content to the site to keep making money? Or is it really set it and forget? _ Will the site rank on its own? Or do you need to invest more $/time to make it rank / attract traffic? _ Is this method over saturated? _ Who is the best seller for these sites on BHW? Even some of the more popular sellers have horrid grammar on their sample sites... If anyone could share advice I would greatly appreciate it!
