Adding the tones (positive, negative, neutral) and emotions (joy, fear, anger, sadness, surprise, anticipation) to the headline and output content. It will help to create the empathy and captivate the audience.

Adding "Ah !", "Oh !", "Hooray !" etc.

Tones will have slightly different purpose than emotions, explained as follows:

"negative + joy" sometimes indirectly means "disappointed"
"negative + surprise" sometimes indirectly means "hate"
