Show overview

Adam explains that statuses like “URL unknown to Google” can mean Google has deprioritised and effectively forgotten pages, and that Search Console may misreport or fail to alert when pages are actively de-indexed.

He describes a “130-day rule” for indexing, where low page quality can affect the status of existing pages.

They also cover index bloat on large websites, the importance of long-term indexing, and practical steps like segmenting sitemaps by site sectioning or seasonality.
