The bot enters these pages one by one and keeps a record of each of them so that they can be visited later.
The pages collected by thespider web they are saved as you can see them when you navigate through them normally, but they are stored as "snapshots", as screenshots so that navigation can be faster. However, even though they are incredibly efficient, they need human help in order to deliver accurate results, as there are many things that can hinder the judgment of these bots.
Sometimes URLs that appear to be duplicates are actually different formats of the same site presented as individual links.
