However, I noticed a massive spike of 404 errors in Search Console.
I sampled a bunch and the issues and they all seem to be the same – Google indexed non-hyperlinks as if those were links.
Here is an example of reported 404:
https://glama.ai/docs/phoenix/use-cases-evals/rag-evaluation
Search Console says it discovered a link to this page on: https://glama.ai/mcp/servers/@Arize-ai/phoenix/blob/4f076b41f023e7e90c98ff7aece47bd1f1f5ebce/docs.json
If you inspect the source code of the page, there are no hyperlinks to that resource.There are now hundreds of thousands of these cases reported in GSC.
I cannot even think of where/how to start troubleshooting this.
