Magic SEO Ball says: Ask again later.
Magic SEO Ball fundamentally accepts Google’s contention that a relatively high number of nofollow links won’t hurt your site’s ranking. But this acceptance is with a caveat: those nofollow links won’t necessarily hurt your rankings now, but this may be something that is addressed in future algorithm updates, whether by adjusting a current ranking factor like Penguin or by adding a new one. You need to ask yourself whether your backlinks profile is abnormal for your industry or niche; if the answer is yes, is that because of something dodgy that you’ve done or because you’re the only one building links the clean way while your competitors are all dodgy?
