<b>SERP teardown: which niches are most volatile, and what that means for strategy?</b>

Ranking stability varies wildly by niche, yet advice is one-size-fits-all. I measured volatility directly to see how strategy should bend.

I tracked daily top-10 composition for 240 queries across 8 niches for 90 days, scoring each SERP's churn (positions changing day-to-day).

— Most volatile: health/supplements and "best X" commercial SERPs — top-10 turned over ~30-40% within a month.
— Most stable: technical/definitional and B2B SERPs — under 10% monthly churn.
— In volatile niches, fresh-published pages broke into the top 10 far more often (the door keeps reopening); in stable niches, incumbents sat for months.

Strategic implication: in volatile niches, frequency and freshness pay — the SERP rewards new entrants, so keep shipping and refreshing. In stable niches, a single excellent asset can rank for years, so depth and link-building beat cadence.

Applying "publish constantly" to a stable B2B niche wastes effort against entrenched pages; applying "build one perfect pillar" to a volatile health SERP leaves clicks on the table during every reshuffle.

Method note: daily desktop scrapes, single locale, non-personalized.

Confidence: medium — locale-specific, 90-day window may miss seasonality.
