Umbrella pagerank is not Google pagerank #60

Closed jedisct1 closed 10 years ago

The "pagerank" value returned here is not Google's PageRank.

The algorithm is similar, but it uses only DNS logs. The ranking might be totally different from Google's pagerank. It is a popularity indicator, but only for DNS names.

A spam web site can have a very high Umbrella PageRank because of the amount of DNS queries observed, yet have a terrible Google PageRank.

Thanks for the clarification. I was typing faster than I was reading documentation.
