I can make this hurdle a quick one, because this has an easy solution...don't ask them to come, give them a reason to come. Clearly its more complicated than it sounds, and the way to achieve this involves a long term commitment.
Your first few weeks of blogging could be disappointing. You may only get a handful of visitors, no comments and even negative feedback. This is because it takes time for you to find your feet as a blogger, and it takes even longer for your reputation to become established.
Keep posting, keep positive, and keep evolving...success as a blogger takes time and commitment.
