> because they drive ad impressions. Could you explain why? If Google replaces SEO trash with decent results, the ads they will show on the Search page will remain unchanged. How would the impressions suffer? Or rather, since Google charges per click not per impression for search ads, how would ad clicks suffer? In fact, I thought low-quality organic search results are purely a negative for Google profits, since users (over a very long run) move their search elsewhere (Tiktok, Reddit, etc.).
