An impact does not the equivalent of visualisation.
Impacts are the number of times an advertisement is played. The number if impacts does not mean the quantity of people listening to your ad, neither to the number of plays you are getting in your song. Your song will get a stream when the person who listens to the advertisement clicks on it (and if your linked URL is a song inside Spotify). Despite this, impacts actually involve a very important value for the increase of the plays of a song in Spotify.
Spotify is a powerful prescriber, as it dictates and directs the tastes of users eager for new sounds. Therefore, advertising on Spotify is an element to take into account. The La Cupula Music team specialized in advertising on Spotify can advise you to optimize the type of campaign that may be best suited to your interests. In addition, from La Cupula Music, you can distribute your videos to YouTube and have your own VEVO channel.
