Google and the Web are tightly coupled. The old contract of if you wrote good content, it would rank highly on Google, was a convenient, organic economic one. You would be rewarded with visitors to your site. Google rewarded with better search results. Readers with good content.
This unfortunately created a race to the bottom.
The intense, years-long effort to DDOS Google search with spammy, low quality, but seemingly good looking SEO-curated content has destroyed the Google and Web experience. I'm not sure Google can ever truly keep up with the volume of spam and low quality. Google tried to react by putting more information on its search results page, but alas, this just meant the content creators valued their destinations that much less.
The prevailing digital marketing firm wisdom created a tragedy of the commons and a crisis in quality web content. "Put a pop up here".. "Add 3 pages of boilerplate to mention all the right keywords" etc etc. When people really want to read informational text in a non-obtrusive format.
ChatGPT does this simple thing well (informational text without the glaring headaches of random websites). So it wins in these contexts.
