The question above says it all really.
I've used the scroll interaction with much of the content on my website (it is initially set at 0% but once you have scrolled it appears). I was using the data highlighter in Google's Webmaster Tools and noticed that all of the content on my website that is initially set at 0% opacity didn't show up on there at all. Which made me think, when Google crawls the website, does it 'think' that there is no content? Therefore my Google ranking is handicapped?
Hope this makes sense?!
