Web search has been revolutionized by popularity algorithms like PageRank, performing a better sorting phase than ever before.
A side effect of popularity-sorting is to leave millions of less popular sites in the last pages of search results; among them are valuable pages/content we miss in our regular search sessions.
Only a very small % of users are browsing results after page 1 or page 2 of the search results pages. The result of this search behaviour is that we mostly navigate across a small set of sites with high popularity: most of the web exists in the dark. Millions of interesting sites remain hidden at pages 10, 50 or 100 of the results of a web search, because of their low popularity.
The idea we started with was to present the web in a new way, removing the 'popularity' criteria from the search. We wanted to bring that sea of hidden websites into the light of day: Similarity classification was a way to re-map internet to let people discover and search a larger portion of the web. In order to make this a reality, we developed PageAffinity a set of algorithms to identify and calculate the degree of similarity between webpages, bringing to light the ‘long tail’ of the web.To create a new Internet map based on similarity, we crawled a large portion of the web. PageAffinity analyzes both the content of pages as well as the linking structure of the web to determine the level of similarity between webpages. The SimilarPages Sidebar is a brand new browser add-on that dynamically provides immediate access to similar web sites and empower your Google daily search sessions.
