Google's ad experience is
night and day different than it was 15+ years ago, and IMO what they do now is much more 'evil' than what they did back then:
1. One big reason that Google became so popular is they clearly delineated ads in the top bar and siderail, but the vast majority of search results were 'natural' search. Google even touted it back in the day: https://www.google.com/about/honestresults/ . TBH I'm surprised that page is still up.
2. For many of my searches ads now take up the ENTIRE front page of content, especially on mobile. It's virtually impossible for any business to survive by SEO alone, because Google has ensured that virtually all "commercial terms" get a ton of ads first. Paying "the Google tax" means business need to buy ads on their own name lest another business bid more and rank higher.
3. In the early days, Google was much less reliant on their "surveillance capitalism" because they already had a great signal to show you ads: what you searched for. Of course, the way capitalism works is it demands they squeeze every additional dollar where possible, so keeping track of everything you do allows them to make more money.
4. One small example, enough has been said regarding AMP and its negative impact on the web and small publishers on HN many times over, so no need to add more here IMO.
