Here is an interview with Alex Goad which may give you some insight into the latest “Google slap” which hit the web on Wednesday the 21st.
Initially I thought that just fake blogs, review sites and thin affiliate sites were getting slapped.
As more information comes to light it seems even well constructed sites and blogs with valuable content are being hit and to be honest that is what happened to us with the Golf Blog.
We were using a traffic lab redirect link which pushed the click through to our testing lab before re-directing to an affiliate offer.
Even though we had it re-direct at the first level we still got slapped.
The common variable tends to be a naked affiliate link that kicks in the slap but again as always there are other complexities involved which of course makes it more challenging to reverse engineer.
Again there are other factors relative to your market.
