What makes a good pop promo?

Any good pop promo has to be eye catchcing and memorable, to do this there are a number of things you can employ.

Font- You can use different sizes and styles for different needs for example if you were promoting an unkown rock band you would use sterotypicaly rock/grundgy fonts that are big and bold etc.

Colours- The same story goes for colours keep it simple there is no need to overcomplicate things, simple plain things often come over more stylistic so if you were promoting a classical album for example compaired to what you would use for pop.

Imagery- Imagery is the key to a pop promo, images and pictures stick in your mind much better than any word or lyric could, making the actuall video side of the promo the most important. The stlye and imagery of the video rely heavily on the genre so what makes a great video for a rap song could and probably would be terrible for say a heavy metal band.
