Let's be real - this is probably a fatal blow for anyone who makes their living monetizing from search alone. Clicks from keywords with informational search intent are not reliable anymore.
At the same time, you must have known that you were operating a little like a Pirate. Or a fisherman with a great lure. Yet you were always on rented waters. Every few years Google would come along and change the rules to improve the quality of links it served.
Real businesses build their own ponds. Many of them in different places. As was said somewhere else in this thread, you have to offer the user something they can't get from AI. In other words, you have to build a brand, which is a lot harder than being good at keyword research and on-page SEO.
I check the NY Times probably three times a day because I like what they offer and how it gets presented to me. I could get that same news from a Chatbot or Google AI Overviews, but I have no interest in doing that. You don't have to be the NY Times to make a living as a publisher, but you do have to offer something that deserves a loyal following.
This sucks for a lot of people, but hang in there and adapt. And remember, short cuts will always burn you.
