worldwide ad campaign

[ElManu Initiation Find all posts View Profile Close ElManu]

I live in Germany and want to start a worldwide ad campaign (conversion) to promote my band's single.
I'm wondering at what time I should start the ad. I want to start the campaign on midnight (German time) but I'm afraid that many countries (like USA) won't have excess because of the time delay.
Do you have any experiences? Should I start the ad after all countries have access to the song?

Brother, first of all.
Worldwide targeting, if you are trying to get Spotify streams, is not the best move. Not every country has Spotify available, you can search up the list online
