Notable pages are pages from your top 20 most popular pages that have something unusual about them. It might not necessary mean that this is the page with the most concurrents on them. This is a place for us to show you that something cool is happening there and it is worth checking out.
Maybe a page has 100 visitors and 90 of them came from Twitter. Maybe people on a page are much more engaged than on your other ones. Or maybe more people on this page go on to read other pages on your site.
This kind of information can be super interesting, but it can also be pretty useful. If you’re getting a ton of social traffic on a page but not a lot of internal or traffic through links, it might be worth putting this page on your homepage or reaching out to your link partnerships.
