Hi Baden, Excellent plugin, just what I have been looking for.
I did a test and it worked out just like you said, google crawling and indexing fine.
I made a dumby post with some random letters and words(something unique that isnt on the web) within a collapse-o-matic expand element. Got post indexed using the video sitemap trick (gets it indexed within 5 secs)then did a search for my unique content. And it is indexed in google.
Thanks again.
