I have several sites monetizing through Adsense and none of my other sites have had this happen. I never use any black hat or grey hat SEO tactics and my site is based on the same subject matter as the rest of my sites. Traffic is increasing consistently and I started using Adsense for it around January 1st. Since then, I've watched page views and impressions go up in Adsense reports until about four days ago. I'm using the same ads.txt I use on the rest of my sites...
I still see Adsense ads when I browse my site. I have to guess that the page views over the past few days are only mine. I'm very active on the site. What could be happening here?
