To calculate RS / KD , Ranktracker first collects the top 10 websites that rank organically for the keyword on the first page of Google.
Then, it calculates the ranking score for the first domain and the score for its page ranking for the keyword. These scores are based on the number of backlinks pointing to the domain and its page. They range from 0 (no backlinks detected) to 1,000 (highest rank).
Once it's done, the domain rank is multiplied by 0.1, and the page rank is multiplied by 0.9. The resulting values are added and then divided by 500.
((domain rating * 0.1) + (URL rating * 0.9)) / 500
The same calculation is performed for each of the ten domains and their pages.
After that, the Ranktracker sorts domains by rank value in ascending order and finds the median value.
0.2 is subtracted from the median. The resulting value is divided by 0.8
(median value – 0.2) / 0.8
The resulting value is multiplied by 100 to convert it to an integer (e.g., 0.6 * 100 = 60). If the value is greater than 1, it's truncated to 1.
