There are two posts that work endlessly on Instagram, and they
work better than you would ever believe.
They are:
- "Double tap if you X!" e.g. "Double tap if you need pizza more
than a relationship in your life" (a double tap on Instagram likes
a photo).
- "Tag someone who Y!" e.g. "Tag someone who needs this in their
life" or "Tag someone who is a great artist"
It doesn't make too much sense, but people will like and tag
those posts all day. Yes, this works.
