There are a number of ways to get followers...

But there are only a few 'good' ways to get followers.

A way that I recommend is 'building your personal brand'.

As you continue to post "good stuff", people will slowly start to notice you.

Another way to gain attention is to visit other people's posts and leave thoughtful comments on them. This will get people interested in you too.

Asking for followers is not usually good because they might not even like what you post... and vice versa. :c)
