Since the Penguin update focuses much of its energy on diversified anchor text, does anyone know the status of 'powered by' links? This is obviously a common practice and my company assists thousands of websites that use our themes which include 'powered by <company link>' so should I worry about getting slapped due to this?
This is not even completely in regards to the recent update. Anyone know if this is something that is at all frowned upon by google/yahoo/bing? Any suggestions if that may be the case?
