How does SERP Seismometer help me?

Similarweb’s SERP Seismometer Tool identifies and analyzes the ranking patterns of Google algorithm changes, in order to help you avoid ranking earthquakes. Every year Google launches many updates and although you'll see lots of buzz online about the big ones like Broad Core Updates and Product Review updates, but the smaller updates can also leave your rankings in a constant state of fluctuation.

So how can you tell if there’s an earthquake coming or if you’re on steady ground?

We developed the SERP Seismometer to provide you with comprehensive daily monitoring of ranking fluctuations and Google algorithm changes so you don't have to wait for the press to tell you that an update is rolling out.

Reading the Graphs

The numbers displayed on the SERP Seismometer graphs represent the change in rankings on a particular date; the higher the Risk Scale, the more Google's rankings have fluctuated. For example: yesterday's volatility level was 61 and today it’s 61 - so we see it has stabled, and take action if needed.

The colors indicate the level of “earthquake risk” to search engine rankings - when you see orange, we think you should check your rankings and take precautionary measures; red means there’s an earthquake coming, and it's time to check your website's traffic and take more serious action to protect your rankings.

  • Today's earthquake risk level is A slight tremor
  • The average risk level this month was Stable ground
