Anecdotal: My hobby tech blog went from 4k hits/ day (all cold Google search traffic) w/ top Google searches in 2019 to about 60 a day today. I still publish at the same tempo and I believe I improved the quality of the blog, but I suspect these days the search engine traffic pushes eyeballs to the walled garden "social media" apps.

If Google is relevant to it.

Google's relevance has been changing with alternate means to discovery (perplexity, chatgpt) than their search.
