Couple of weeks back, I purchased one website with 100 subdomains. The idea is to earn $1 a day from each website. So, what tool is best recommended for promoting 100 websites easily. Would prefer advise on a tool that doesn't have a recurring cost, but will consider good tools with recurring cost if you think it will help me achieve my target. If you have some success story to share with the tool that you are using, do share your story.Thanks in advance for the answers.
