Google has this page of SEO case studies and success stories since 2019 and they’ve updated it a few times I think. Recently, a Mariachiara Marsella asked John Mueller if Google could add new case studies.
John Mueller responded at Mastodon, “I find it quite challenging for us to do these since search is so dynamic.”
I assume John is saying that since Google Search changes so often, not only the core locations but also the search functions, the production of these can often lead to results becoming out of date – quickly. So even by the time Google gets proper approval to publish one of these case studies, the results of the study may have gone the other way due to a ranking change or, a feature being demoted, or maybe even sunset.
This then makes me wonder if Google will drop these SEO case studies all together?
Here’s a screenshot of the page as I see it today, just in case (click to enlarge):
