How can I get followers on Tumblr?

[Stone]

Post original content, and tag it so that people can find it.

For instance, my last post was about that dad that refused to take his son to Mcdonalds...
I tagged it Mcdonalds, and bad parenting.

And then I checked out all the posts that people had written using those tags.

Once you have a body of work, you will see people that post similar content liking and reblogging your posts, and occasionally even following you.

Ok... That is how you get legitimate followers... there are ways to get numbers of followers... instantly... but I doubt that any of those will have any interest in your posts... And... I'm not sure whether those fake followers would be a violation of terms...
