Comment, read and appreciate OTHER member's blogs. This is definitely important. It gives you more "Face" on others pages, thus individuals can visit your page when they see you post or see that you are a "follower". NOW before we get the wrong impression, I DO NOT recommend doing this purely to just become a follower of everyone and leave non-substance comments on their blogs, this might feel great in the short-term, but for Long-Term sustainability, it just will not work.
Have pure interest in the blogs that you read, follow the blogs that tend to your interests and send messages/comments on how you felt about them and how it relates to you. Having this will allow more traffic to your blogs, more connections to receive advice, guidance and tips on what you are doing wrong, right and what to improve upon.
In conclusion, be nice and open to fellow members on blogger and other blog web-pages. Show genuine interest and display your feelings in a kind post/comment. Rewards will come if you follow this and appreciate others work on their blogs. This is yet another step to create passive income online from the blogging-point-of-view. Thank you for reading and best of luck.
