I'm getting more spam than visitors and orders to my sites. I thought it was temporary, but it's getting a little unnerving now.
Did your site rank change or results in search change. That can cause it to slow down and time of the year can slow sales for some products.
Actually my keywords have moved higher in the SERPs. I'm seeing slowing on Amazon and the ecommerce site. I think the kids are going back to school and people just have their attention on other things. I know it'll turn around, but I didn't think it would drop off this much. Then again, if I had a perfect understanding of the market I'd be a billionaire.
