Repetitious content refers to channels where the difference between the videos can not be determined easily because of too much similarity.
This policy is taken from AdSense program policies and applies to your channel as a whole. If you have many videos that violate the guidelines, monetization may be removed from your entire channel.
What can be monetized
You can create videos that follow a similar pattern but the substance of every video should relatively vary.
Same intro and outro for your videos, but the bulk of your content is different
Similar content, where each video talks specifically about the qualities of the subject you’re featuring
Short clips of similar objects edited together where you explain how they’re connected
What can't be monetized
You can't monetize content that’s created using a basic template. You can't spam the platform with copies of the same video and earn revenue from them - it will not help you get more viewers and subscribers, too.
Content that exclusively features readings of other materials you did not originally create, like texts from websites or news feeds
Songs modified to change the pitch or speed, but are otherwise identical to the original
Similar repetitive content, or mindless content with low educational value, commentary, or narrative
Templated, mass-produced, or programmatically generated content
Image slideshows or scrolling text with minimal or no narrative, commentary, or educational value
