I have breadcrumbs on my site, and the anchor text for the links are an exact match for the keyword I want to rank for. So in other words, it's "rich" anchor text.
An example of my breadcrumbs could look like:
Home > Apple Cheats > Apple Points Cheats > Apple Seeds Game Cheats
Well I've also used RDF markup to construct my breadcrumbs (https://support.google.com/webmasters/answer/185417?hl=en#) which will allow Google to recognize it.
So overall, do I need to worry about exact match anchor text that will get me penalized by something like Penguin? If so, I can remove the breascrumbs easily.
