They bleed traffic over weeks, and by the time it shows up in a monthly report the rankings are usually gone. The point of this skill is to catch that while the page is still on page one, when a refresh still works. ## Finding candidates 1. Call `list_gsc_sites` and confirm the property. 2. Call `gsc_decay`. The defaults (28-day windows, 100 baseline impressions, 20% decline) are a reasonable start. - **Short windows are noisy.** A 7-day window will surface normal week-to-week variance as decay. Prefer 28 days or more unless investigating something specific. - **Raise `minDeclinePct` if the list is too long**, rather than cutting it arbitrarily. A shorter list of worse cases is more useful than a truncated list of mild ones. The tool compares the recent window against the equal-length window immediately before it, with no overlap. ## Reading the results `lostRank` is the field that matters most: - **`lostRank: true`** — clicks down *and* position slipped. Competitors are outranking the page, or its content has aged out of relevance. This is the actionable case and is where a refresh pays. - **`lostRank: false`** — clicks down at flat rank. The page is still ranking where it was, so rewriting it
