Here's the situation: I browse Tumblr, and then I go to, let's say, Youtube. What is the word for the action? The noun? It's not conversion, or click-through, I just move from one website to another. I don't think it is browsing. Browsing is when you surf the web, and I need a noun for the single action of shifting from one website to another.
Mind you, a NOUN is needed. There are many verbs for this action.
