You are absolutely right. YouTube is the second most popular search engine after Google.
Thank you for the insightful information based on practical tips of advice on how to increase YouTube earnings. I believe the best thing is that your approach is supported by your own experience.
It would not be an overstatement to say that you've really hit a goldmine, since most YouTubers would not expect this CPM even in their wildest dreams.
I assume that this is not all due to good luck, since using the right keywords and making useful videos to offer value to viewers and answer their questions play a huge role in achieving this high CPM.
Well done!
