Site Explorer allows you to explore all the pages in a particular site – when I did a lookup on this site, it found over 800 pages! I must be a lot more prolific than I thought!
Some observations – by exploring on this site, I was able to quickly ascertain that the most linked to article is the one I wrote on how to stop comment spam without using comment spam plugins (it is no. 2 in the results). By then clicking on “Explore the url” – I was able to see all 77 inward links that this page has.
The site also provides access through web services APIs and the ability to export the data to a TSV file for further analysis.
This is definitely a useful little tool – and it will be fascinating to watch what applications people develop for it using the APIs.
