Welp after over a week I have talked with as couple legitimate/respected SEO firms and both confirm a penalty.
I am a little bit in shock as I really have babied this site. Never bought a link, all my own content, no tricks and so on.
It appears I have "trademark" penalty in which even when you search my domain name with out the TLD. From what I have gathered it is from being non-compliant as well as deceptive in some way in Google eyes.
I am not completely sure what could have caused it because I have been doing the same things for over 5 years which continued to grow me Google traffic. I do run 2 sites, one is just a database of products, these are affiliate products but the database, checkout and all is set on my own domain and hosting. I use the site which has the penalty as a place to write articles and so forth with links to my product site without. Google never had a problem with this before, but somehow I feel the problem may stem from this.
I recently created a new banner for my site when I redid it a couple months ago, on it I use the name with both the .com and .net on it because I wanted to have visitors feel more comfortable knowing both sites were owned by me.. Could this be a problem in Google?
My backlinks appear fine, never bought a link, I don't see anything that looks suspicious.. 1200 backlinks all from decent sites, all but 50 one-way links no red flags and all with varying anchor texts.
I am looking for any advice as to what to look at the resolve this from anyone who has been through it and knows what they are doing.
Thanks for any help I really need it!
