For the past month and a half Adsense stats such as CTR, CPC and RPM have been down dramatically. They are finally beginning to return to normal, but my page views are still much lower than they have been in the past, is there any reason for this? Is anyone else noticing this as well? Is this just happening because January and February are slow months? I haven't done anything different to my site so there's no reason this should be happening. Please help if you've experienced this with your site or Adsense in the past. Thank you.
