One section of my site features quizzes (on a few different topics).
The index page for each individual topic links to its 3 to 5 quizzes. This topic index page also contains the study materials (text) for the quizzes.
The quiz pages themselves would be classified as thin content. They don't really exactly duplicate the content of their topic's index page (study guide materials) but clearly the content is similar.
It seems that I have (sometime in the past) placed a canonical tag on each quiz page (using the URL of that topic's index page). Evidently I have also placed a <meta name="robots" content="noindex"> directive on each quiz page also.
Now I'm not so sure I've implemented things properly.
My goal is simply to state to Google that I realize that the content on the actual quiz pages is thin and very similar to the topic index pages. I don't care that they (the individual quizzes) are not in the Google index. However, I would like any inbound links coming to the quizzes to pass link juice to their topic's index page.
What's the proper way to do this?
