Distribution of SEOMOZ Ranking Metrics across all Monitored Websites

[James77]

Hi,

I'm looking into building a tool which would incorporate SEOMOZ ranking metrics and I have a few questions with regard to the ranking data which will help me develop it correctly.

I have done a few searches, for the information but haven't found an answer to these questions on seomoz - if they exist somewhere then I would be grateful if you could point me in the right direction.

1/. When looking at the values of metrics such as MozRank and DA, is there any information on how this values are distributed amongst the ranked website - EG The mean / median values of DA and MozRank etc of all websites monitored is X & Y . If there were any distribution graphs for these values then even better.

2/. Along the lines of the above - are there any online resources showing similar information for google PR?

3/. What is the calcuation used in the scale of MozRank and DA  - ie We have a scale of 1-10 for these values - be we also know the scale in not linear but logrithmic - ie Double the Links of a DA 5 website and you would not end up with a DA 10 website - so what is the calculation which defines the scale. A WBF about google PR by Rand indicated that a value of between 8-9 is used in Google PR - but what about the values used for DA and MozRank etc?

Many thanks for your help

Hi there!

I apologize for the late response, I had to do a little research on this question Here's what I know--

1-- We don't track data on the metrics across all ranked websites on a regular basis. Although we have an interesting blog post by our resident "numbers" guys with distribution from our last index.

2-- I don't know of any online resources that show this information for GA

3-- I was going to explain how we calculate MozRank and DA, but these blogs do a much better job than I could: MozRank & Domain Authority.

I hope this helps. Let me know if you have any other questions!
