Easy answer? When you put the happiness of someone above your own.
Yes that is love but is it healthy love? Someone said to make a person happy, be happy yourself. That works if the love is mutual. So the deeper your feelings are linked the deeper the love?
The love of a parent for a child can be very one way. The elder living a vicarious life through the happiness of the younger. The young seeking approval and direction to be happy but unaware of the needs of the adult, giving happiness just by being happy.
The love of friendship? Just shared interests and experiences?
The love of an object or place? It makes you happy or thinking about it makes you smile.
Love is giving smiles or making happy? I know it’s more complex than that. I could write many more words and still not get there.
