Google's demise is self-inflicted. They broke search by prioritising ads, then trusting the wrong, big publishers (eg every listacle from a big media network), broke their advanced search controls (domain blacklists, quotes that mean quotes, plus-and-minuses to alter things). Then they added their own LLM's analysis to searches, admitting that that their SERPs are dead. They were in this death-spiral well before LLMs…
Roughly 30% of the YouTube ads I get served recently are 10minutes long or more. At least once a day I feel like I'm reporting some 50+ minute long alternative medicine scam ad.
