When will my Tumblr activity become "noticeable"?

[Sam]

1. Tag your posts.

2. Reblog and like posts.

3. Post quality material.

4. Follow lots of other people, especially those who have blogs similar to yours.

5. Have your friends follow you.

6. Post pictures. Most people are more likely to follow you if there are colorful images on your blog.

7. Put your Tumblr URL on other social networks like facebook, twitter etc.

8. Be on your blog as often as possible.

9. Always be respectful of your followers.

10. Get a nice theme and customize it; most people with lots of followers have aesthetically appealing blogs.
