I run a few sites that as well as other programs, also make money via Amazon Affiliates. Two of these sites, prior to Sep 16/17th, sent around 1000 clicks per day, and 400 clicks per day, respectively. Since the 16th/17th, both are down around 50% — down to around 600, and 250-300 per day. Traffic has been completely stable.
Has anyone else experienced this, and does anyone know the cause? Has there been a change to the way Amazon tags links that I haven't been alerted to? And have you managed to fix this?
