Is there a way to automatically append an identifier to a page URL when it is bookmarked in the browser, perhaps something in the document head that gives the browser a directive or an onBookmark JavaScript type of event? I’m looking for ways to further segment my direct traffic in Google Analytics (if you have other ideas for doing that not related to bookmarks, please share them as well).
Example:
http://www.example.com/article
When bookmarked becomes:
http://www.example.com/article#bookmarked
I don’t think you can reliably do what you’re describing. The best you could do is have a button on your pages that uses window.external.AddFavorite, and then specify your hashed address. It will work for the people who use the button, which may be better than nothing.
