TouchGraph connects the dots of Google searches
The TouchGraph Google Browser is a new tool that visualizes the connections between web sites.
The TouchGraph Google Browser is in fact a marketing ploy of a company trying to sell its technology to companies facing information overflow. That’s fine with us, because nowadays most of us are struggling with too much information and too many search results.

If you do a search using the java-based Web service, it will give you the search results in a pane to the left of the web browser window and a graphic rendering of clusters of the same web sites to the right.
Topic clusters
The image above shows a small part of the clusters given by a search for the term “search engine marketing”. Yepp, the big P is Pandia.
If you let your cursor hover over a result (colored circle) a small box will pop up with the name of the relevant Web site. If you click on that site, the corresponding circle becomes the centre of that cluster, and you will see what other sites are related to that site.
Clusters of conceptually related websites (where every site is related to every other site) are given one color. You may change this color if you feel like it.
If you turn off your pop up blocker, a click will also open the the home page of the site in question. There are also buttons for changing the number of clusters displayed, filters and much more.
Similar pages
The presentation is clearly built on an analysis of web site inter-linkages.
The TouchGraph Google Browser actually uses Google’s Similar Pages function, helping TouchGraph identify network of similar pages on Google.
Mutual links can contribute to two pages being identified as similar, but frequent third party mentions of the two web pages together will also mark them as related.
Analyzing one site
You can also enter a URL in a search field in order to analyze the neighborhood of one particular site.
