Content production is a lot like music in the sense that not every song is a hit.
You need to have a firm grip on reality to understand that some of your content is a flop.
Also, sometimes, the content you post isn’t worthy of promotion.
Save your money and promote only what you feel is the best content.
Sometimes you’ll know what content is worthy of sponsoring by the time you’re done creating it.
There will also be those times when a piece of content unexpectedly takes off, and that too is a good candidate for sponsoring.
The entire purpose of sponsoring your content is so that it gets in front of as many people as possible.
