Nothing special according to Algoroo also
In all honesty, nothing really noticeable here.
But many people in some groups talking about this Issue. Their Ranking Declined, Some saying they can't find their site in first 100 but they were on the first page. But they all are doing Amazon affiliate with a micro niche site.Most websites I run got declined by .002% or .020% I wouldn't say it's that big of a deal currently.
