<b>The rank trackers everyone watches during volatility</b>
This week on the radar: where pros look first when SERPs start shaking.
Confirmed
— <a href="https://www.semrush.com/sensor/">Semrush Sensor</a> — daily volatility by category; the 'High' band above 8.0 usually precedes a confirmed announcement by a day or two.
— <a href="https://algoroo.com">Algoroo</a> — tracks ~17k keywords, plots a 'roo' score; useful for a second opinion when Sensor and Mozcast disagree.
— <a href="https://moz.com/mozcast">Mozcast</a> — the original 'weather report', reported in degrees; long history makes baselines easy.
Read this
— <a href="https://www.rankranger.com/google-algorithm-updates">Rank Ranger Risk Index</a> — splits volatility by niche (Health, Finance, Travel), which matters because updates rarely hit every vertical equally.
The takeaway from watching all four: agreement across three or more tools is the real signal. One spiking tool is noise.
One to bookmark: Semrush Sensor's category view — it tells you whether your vertical is in the blast radius before you panic-audit your own site.
