I built a website out around two and a half months ago and have been drip feeding it PBN links (quality domains that I found myself - healthy link profiles + no previous PBN history) over the past month.
Between the 9th and 12th of May I saw a very strong uplift in rankings (from position 35 to 15) for a very high volume term (see: http://imgur.com/QsHXJ0b), however after some days at this position it suddenly dropped back to where it was previously... Crucially, no other keywords saw any form of initial ranking uplift or subsequent decline during this period.
I currently have around 8 PBN links pointing to this domain and 4 exact match anchor texts - I realise that this ratio is horrendously over optimised at the moment and I intend on reducing this with brand/URL based anchor text moving forward.
My question is: Is this a penalty, or was it simply a ranking fluctuation?
