Google Makes hundreds of algorithmic changes to their search engine each year. Tracking both documented and others that were not made public becomes difficult if it were not for the tools from MozCast and the SemRush Sensor.
For clients that have a strong (or primary) reliance on SEO to bring in organic sales, keeping track of the effects of Google' algorithm updates is paramount. Any update could significantly change the volume and/or quantity of the traffic their website enjoys. These tools allow us to measure how turbulent these changes are and they also provide a comprehensive timeline of changes in the past.
Any person with experience in SEO should be familiar with these tools.
