I would argue Google also focuses on large corporations. I have a post on my blog that ranks really high (currently spot 3 for its keyword) in the bing/yahoo/ddg world but ranks after stack overflow, medium, reddit, youtube, etc. on google for the same keyword. (I did nothing to on this post for SEO it just organically showed up high on bing/yahoo/ddg)

I should also mention I have no ads of any kind on my blog.
