It does not follow that people making more searches means people are having more successful searches. If google found the exact thing you were looking for and put it top centre in the results, would the number of human searchers stay the same but the number of human searches drop?
Again, then why are people using Google more than ever?
I don't really see how "dead internet theory" explains that. If it were as bad as you claim, surely usage would be plummeting? But it's just the opposite.
The policy described in my link is literally about making each user search more to get the results they want in order to drive more ad revenue. That would create more searches and a less good user experience.
AI is not and cannot be search. Search is dead and has been for a few years now. Search has seemingly been subsumed into the LLM monster, considering how "fuzzy" queries have become (probably because they're not hitting the search algorithm without being massaged by "something else"). Significant portions of the web have been purged from Google's index, which means that neither Gemini nor Search can present those pages to users.
When people say "search is dead", I feel like you and I live on different planets.
If I have an idea of what I want, Google search works great. On the rare occasion I don't know the specific thing I'm looking for, Gemini points the way.
It had never ever been easier for me to find what I'm looking for on the internet, since 1993-1994.
I do wonder how much browser, location, and language plays into this.
I believed these sorts of statements a few years ago, but not anymore. Results were hit-and-miss enough to give the benefit-of-the-doubt. They're now so bad that I assume bad faith, either on the part of the speaker or Google.
Instead sites adds Gemini integrations, which are targeted based on prompts. When you pay enough, Gemini recommends your shop and AI buys the stuff for the target audience.
Google considers the consumer's side, not just the publishers. Users often don't want to visit someone's website (and then dodge ads and cookie/newsletter/notification popups). If the query can be answered without veer visiting a website, so much the better.
