This got too long, but to summarize my point there's a vast amount of content on the internet and those people feeling that someone not finding them via google is a cheat are over-reacting. The world is so big that there are lots of people no one ever hears about, who may be doing interesting stuff. Feeling that people don't find your cool stuff is a complaint you can make against google, facebook, instagram, maybe bing if anyone used it, any indexing site.

For every person that youtube or whatever other ranking site give them lots of viewers, there are millions of people posting stuff that hardly anyone ever sees. It's not a conspiracy that no one really watches my son's youtube game discussion site. There are thousands of videos every day created with similar content.

So all these people mad that they don't have lots of viewers, a bunch of that can be explained because there are lots of people doing the same thing.

Now for the people who used to get lots of views and then things drop off after a google ranking change, sure, the change must have had some impact. So your site with videos in say Farsi about how to exercise with a particular style of workouts, probably there are 100 other people doing videos for working out in Farsi or whatever. There's basically no way google or anyone else can balance it out. They make changes that they think will serve their users. Google works for a lot of people because it's a good clearing house. But it's good for people cause they can find things they want. Google cannot show all the thousands of videos every day on say fortnight. But my son's video game discussion site hardly gets any views. but thats because he's not famous and he's not doing anything that other people are.

I also think people try to make their site go higher by paying for links to their site. In a previous job, (I heard) they paid someone who was a wikipedia editor to create entries for their company and the founder, of course this is a known problem.

I think I'm sounding like a google or big company apologist. I have seen a similar issue in phone apps. My friend had a bunch of android and ios programs for tracking various things that he sold for a dollar, and the ideas got copied by people doing similar things multiple times and now he's just one person is a sea of solutions. He used to get a few $100 a month from people buying his $1 software, now he gets $5. It's not a conspiracy.
