> Search ads work because they're largely indistinguishable from the organic content. I'm not sure this is true. Surely they are more lucrative when they are indistinguishable, but for a lot of Google's history they were very noticeably different, a fact Google even prided itself on, and bragged about. Seems like it was growth requirements that changed that, not whether the ads were originally lucrative when people could tell they were ads.
