now we have all these annoying site with the endless scrolls such as facebook and tumblr. i see that my link will show up only after 1 scroll (i.e., on 2nd page). if I look at the page source, I will not find my link. So how does google find the link? reason I ask: I am trying to backlink my backlink. if i backlink to the page with endless scroll but my link is not in the page source, how is it going to work? somebody help?
