How to promoting your Art on Social Media?

I think almost all artist has Instagram and Twitter account but

we are struggling with promotion sometimes.

I found one tip for it so I would like to share it today.
When you post your photo or text, what do you write?

I just text like "New painting. Title is xxxxxx" or only title.
That's all...

However good attract attention words is "question" such as "New post, what should I title for this work?"
Something like that.

Or you put two paintings and text "which one do you like?"

Honestly, I have never tried it yet but I should try it.
