Dejan Authority Metric
Introducing a domain authority metric which balances popularity and centrality.
Today we're sharing an internal domain authority metric designed to balance popularity and centrality of a domain on the internet. For those of you who want to check your domain(s) feel free to jump straight into the public web interface:
The DAM database contains roughly 300,000,000 unique common crawl hosts, but most are concentrated at around 35-45 DAM. We can call this your "average web". Anything below 30 is of really low impact and influence as far as the web topology is concerned. In fact the scale really starts at DAM 20 as the rest has been filtered out to save compute resources and storage space.
The public authority metrics are log scaled for simplicity but they in range from 0 to 1,000,000 in raw metrics.
In practical terms, that means that the difference between 30 and 40 isn't as great as 40 and 50 and to get from authority 99 to 100 would be more difficult than getting from 0 to 50.
This also means that 31 is a little bit stronger than 30 while 81 is a fair bit stronger than 80. So higher up in the metric you go, more important are the granular values.
Example:
YouTube: 99.807016
Instagram: 99.737763
linkedIn: 99.330713
Since they all sit in the god-tier of the web, we're not paying closer attention to the values following 99 to get an impression of relative strength to each other (80, 73 and 33).

The Dejan Authority Metric (DAM) is a product of Harmonic Centrality (HC) and PageRank (PR) and balances the strengths of each in evaluating the influence and importance of web pages within a network. By integrating the proximity insights of HC, which highlights the closeness of a node to all others, with the influence propagation characteristics of PR, DAM provides a more comprehensive assessment of a page's authority. This balanced approach ensures that pages are not only important due to their structural position in the network but also accessible in terms of their relational distance to other nodes. Dejan Authority Metric allows for more accurate identification of key pages that are not only well-linked (as emphasized by PR) but also centrally positioned (as captured by HC).
