@fyrstikken, if I want to sure to avoid confirmation bias in my search results, i make sure to be logged out of my Gmail and other connected services when using Google to do any searches. People forget that Google will keep track of the pattern of your search history for the sake of convenience. I usually use DuckDuckGo: https://duckduckgo.com/
As for YouTube, the best bet is to use your channel to direct traffic towards your own website for the products and services that you're selling and not to rely on making money through AdSense...
