What would proof be? Over a period of time, they have clearly de-prioritized organic search results by pushing them down the page with ads, widgets, and so on. They used to engage more directly with content producers. Matt Cutts was often called the "Head of Web Spam". When he left, they dissolved his role and spread it around to several other people.
"Deprioritized" means moved down the fold of the page. Like, for example, the 3-4 ads at the top that used to not be there. And various other widgets that used to not be there. Ads in SERPS started out in the right hand sidebar only. Such that organic results were at the top. They were slowly moved down over time by a slow rollout of more ads and widgets. There are many queries now with ZERO organic results above the page fold.
None of this is in dispute, so I don't feel compelled to dredge up old screenshots or examples.
Comparing the page layout to competitors isn't especially helpful when Google has 90%+ market share in search. Google is defining the standard for others.
Why don't you give any examples of these queries? There's no point in comparing to say, 2008 Google, there are many of orders of magnitudes more sites. You can't expect old algorithms to keep up. The main thing that matters is how long it takes to find what you're looking for.
Can't say I really get your point. You're willing to complain and go on this long tirade, but not to give a single query example? The one you gave in your original post was already debunked easily enough. You're saying these things as if they are a fact - I disagree with you, it is in dispute. If we're going to just take random claims are facts, then I'll say Google's results are better than ever.
Google's market share isn't really relevant. It's very easy to just use Bing or any other search engine. I actually use Bing half of the time since it offers rewards.
I didn't give any query to be debunked. I gave an example of a query to see the copycat sites. It does that just fine. Re-read it with some benefit of the doubt maybe? Your rant seems to be based on the idea that my upthread post was something that it wasn't. I did note that one copycat site was ranking above SO, but that was secondary.
As for a query with a shit ton of ads and widgets? Try vegas hotels, or anything else with lots of widgets and ads. The travel space has a lot of them.
Would you please make your substantive points without degenerating into the flamewar style? You did it repeatedly in this thread, and worse each time. That's the opposite of the direction we want things to go here.
Proof of what? That google didn't used to have ads above organic results? That they added more and more over time? That some queries (vegas hotels) have no organic results above the fold? Those are all common knowledge. Burden of proof of the opposite would be on you.
I don't happen to have a historical screenshot history of SERP results specific to StackOverflow copycats, no. I'll concede that.
