Ultimately, the process resulted in 516 changes that were determined to be useful to users based on the data and, therefore, were made to Google\u201fs algorithm.  Most of these changes are imperceptible to users and affect a very small percentage of websites, but each one of them is implemented only if we believe the change will benefit our
