Ranking pages: Hubs and Authorities

This week we are still talking about web architecture, and how we can work on it through Safecont.
One of the least known parts of our tool is the page listings of a domain by Hub or Authority scores. Although we do not usually mention them much in our videos, these scores also serve to measure the importance of the pages of a domain and improve the architecture of a site in an alternative to the typical Pagerank algorithm.

While Pagerank focuses on sorting the pages by the probability that they are visited at random, the HITS (Hyperlink-Induced Topic Search) algorithm is based on the idea that there are two types of pages on the Internet:

Hub-type pages are those that, although they do not provide much information on a topic, link to the pages that do.
Authority type pages are those that contribute content on a topic to a website and are therefore linked by many Hubs pages related to that topic.

It is necessary to emphasize that the two types of value (Hub and Authority) are not exclusionary. The main page of a site usually has high scores in Authority (it is linked from the whole site) and Hub (it links to many pages with high Authority scores). Let’s see how we can use these scores to improve the structure of our site.
We have placed the page listings by their Hub or Authority score in the “Architecture” tab of our tool. In that section you can find two links to the lists of URLs ordered by their weight as Hub and as Authority. Let’s see some examples:
Example: eu.billabong.com
This website is the online store of one of the surfing fashion brands. If we look at your list of Auths we see the following:
As you can see the root has a high Auth weight, this is logical because it is linked from most pages of the site. However we see a curious thing, the Hub score is very low.
Normally it would have a score close to 1.0 because the usual in an e-commerce is that this page
