My impression is that the decline of search engines has little to do with search ads. It has more to do with a decline in public webpage authoring in favor of walled gardens, chat systems, etc.: new organic human-written material that once would have been on a public forum site (or home page!) is today often instead in an unindexable Discord chat or inside an app. Meanwhile, spammy content on the public Web has continued to escalate; and now LLMs are helping make more and more of it.
But most of LLMs’ knowledge comes from the public Web, so clearly there is still a substantial amount of useful content on it, and maybe if search engines had remained good enough at filtering spam fewer people would have fled to Discord.
