i don't really think this is the solution.
Other people will answer " do a better SEO" i guess.. that is not useful at all
The reason for my answer is pretty clear, I hope you can guess that for yourself. And yes the solution for his problem is that he needs to upload more videos without the lazy mentality. No one here gave a helpful answer, so I will do that really quick.
The algorithm: CTR and Audience Retention is the most important thing. Make clickbait or eye catching thumbnails that the viewer wants and make the first 5 minutes of the video as engaging and interesting as possible, the next 5 minutes you just stretch the content.
Your target CTR is above 10% and Audience Retention 4 - 5 Minutes.
Step 1: Keyword Research
You need to research when your channel is little! Find relevant keywords in you niche.

Use YouTube's search to get a picture on what is relevant at the moment.
Step 2: Video creation
Begin the video with a question etc. do not introduce yourself! Talk as simple as possible and with high energy.
Adobe.com, download premiere pro and photoshop, watch tutorials on how to edit the videos and thumbnails.
Step 3: Uploading
Write a description above 500 words, either post what you said at the beginning of the video with all the keywords or give the viewers the informations about what they are going to watch. Put some video links of competitors that are ranking for your keyword in there.
Make 5 - 10 Videos and you will get monetized in ca. 2 month, don't stop uploading.
