Under the Bonnet

AccuRanker’s Google Grump rating is based on a unique algorithm, calculating the average number of rank changes, across the top 100 results per keyword.

It monitors:

  • 30,000 randomly selected keywords.
  • Split 50/50 between mobile and desktop.

Creating a result

  • We loop all 100 rankings and compare them to the previous day.
  • If the URL has dipped or fluctuated, it is subtracted from the position the day before.
  • The final index number for a given keyword is calculated by finding the sum of all differences - dividing this by the number of results (normally 100).
