My site speed is around 75 to 77 according to various tools and 3 seconds load time.
Is there anyway I can contact the Adsense team to look into this? Otherwise what I will do is let adsense run the rest of today and also tomorrow and see if its gets back to normal. If not, I will put Chitika on the site from Saturday as the weekend is quieter. Chitika can take two days before showing regular ads.
Its very bizarre how earnings can fall 60-70% without good explanation.
I had a coder do some extensive work on the site a couple of months ago and I thought maybe some of revenues perhaps was being stolen, but then I can see my adsense code, and just to make sure no foul play, I replaced the code several times in the last couple of months.
