I’m subscribed to a YouTube channel that’s fairly new but it has around 50K subs. Two guys are making niche websites together, putting ads on them for profit, and then selling them. So they have a lot of tutorial style videos and giving tips on SEO optimization. They both claim that Google’s algorithm doesn’t work like before and say you really don’t need optimization these days. They even claim that some of their websites are even not published in Google’s search (are not submitted manually). What would you say about that? Do you concur?
