I noticed a couple of my sites have been filtered down to a #6 SERP ranking for primary keyword (and domain name keyword). Page one, position six.
I remember receiving the same filter about 7 years ago on one of my sites. If I recall it lasted for 3 months.
Does anyone know of the problem to this filter/penalty?
It was first written about here.

Prior to this the sites were ranking well, #2 or #3 for most keywords with only minor, non intrusive link building. Nothing that competitors don't do X10 and rank in top spots.
