so if not clicked on the content is not visible
Yes ok visually, but what you see in the html source code? Are you using ajax to pull the content right then, or is just some css/js that hides it initially. These are 2 different things. If the html source shows the content 2 times, the spiders also see it 2 times while regular viewers see it one time.
