• Make great posts and even better comments
• Follow those bloggers who want to reward your good comment or post
• Participate in competitions, be active
  Be honest and do things with a pure heart
• Try to make your own style, you make a brand of yourself
• Ask successful bloggers to give you advice on how to make a real post, contest or some idea
• Be disciplined in your work, write comments and posts every day of the week
• Make your own strategy and success plan

You have said it all basically but if all this are been done and yet nothing to show for it, remember never give up winners never give up.
@dobartim am inspired by your words.
