What you get
- Daily volatility score per keyword (0–10) computed from top-20 URL churn — not a global weather index.
- Automatic overlay of Google confirmed algorithm updates so you can attribute drops to a specific update.
- Alerts when a tracked keyword's volatility spikes 2σ above its own baseline — no false positives from a noisy neighbour.
- Volatility timeline sits next to rank history in the same view, so cause and effect line up on one chart.

Frequently asked questions
What does a SERP volatility score of 7 mean?
7/10 signals major reordering — at least four of the top-10 URLs shifted position or disappeared in the last 24h. Treat it as "your ranking is not stable, do not push new content yet".
How is this different from MozCast or SEMrush Sensor?
Global weather indexes tell you the internet is stormy. LemRank scores each of your actual tracked keywords, so you can act on the ones that matter to your revenue.
Can I get alerts only for algorithm updates?
Yes — filter alert rules to "volatility ≥ 6 AND known algo update overlay" so you skip the day-to-day noise.
