Google Update Radar

Is a major Google update in progress or are only my rankings affected? With our Google Update Radar you can see at a glance if there are major changes in the Google SERPs.

Today’s SERP dynamics: 6 (high)
The Google SERPs are churning! This looks like a major update.
Today’s SERP dynamics: 2 (increased)
We are measuring movements in the SERPs. Although not yet a major Google update, there is an increased SERP fluctuation.
Today’s SERP dynamics: 1 (low)
The fluctuation in Google’s SERPs today is about average. There are no unusual movements being measured.
Today’s SERP dynamics: 0.6 (below average)
Today, less happened in the Google SERPs than usual. The fluctuation is below average.

Normal SERP movement or Google Update?

Google’s search results are constantly on the move: new content is added to the index, others lose importance or are deleted. These movements are called Everflux – a continuous fluctuation of results and positions in the SERPs.

However, Google also makes major changes to the algorithm several times a year. In order to be able to distinguish such Google updates from the normal shifts, there is our Google Update Radar.

Based on daily updated data, we show you how relevant changes in Google search results are. You can see at a glance whether a general Google update is in progress or only your rankings are affected.

Google Update Radar: how to measure

For the daily updated visibility index we measure the rankings for many millions of keywords every day. We use this data for the Google Update Radar to measure both the extent and strength of changes in the Google SERPs.

We first check how many of all the domains recorded have experienced above-average changes in visibility (extent of the changes) and in a second step we look at how strong these shifts were (strength of the changes). On the basis of these two values we determine an index value for the display in the Google Update Radar.

This index value is scaled so that the average value over the last 90 days is one. Daily values of less than one therefore mean below-average volatility in the search results, values of over one mean above-average fluctuation. If we see a value above 6, we assume a relevant update of the Google algorithm based on past observations.
