Google isn't trying to sell you the best site. They're trying to sell you – ok well your click to the highest bidder.
Which explains why they push an AI Summary to the top of most searches which discourages clicking on any of the search results.
Or not.
AI summary seems like the same play, even if it hurts their current ad business some. After all why search for stuff when a chatbot can just tell you? Makes sense they'd view it as an existential crisis and push their AI.
Google will be well positioned when ads start being added to AI for most users.
