Example 1: Small Channels have different rules, they don't perform the same as Larger Channels
Examples: If you're uploading a 4k video onto a larger channel it takes about 2 minutes to upload & if you're uploading a 4k video onto a smaller channel it takes about an hour or two to upload.
Example 2: this comes from multiple clients channels, I have seen the behavior over and over again, publishing a video have a spike line & a flat line meaning that the algorithm is to test the video & then stop giving impressions to the video for a period and sometimes that pattern will repeat.
Example 3: Give the YouTube platforms more data! Give more videos / more content!
No matter where you are with your channels whether you have a larger channel or a smaller channel If you find ways to give YouTube more content, it's almost always a positive thing as long as those more videos are quality videos.
