WTH: Adsense expert

[daytona4me]

Want to hire an a adsense pro.

I'm a decent size forum with January's pageviews at 1.7 million.

I've seen my Google adsense revenue drop significantly since the beginning of December to the point that it's 20% of what it was all of last year.
I'm not an expert and I'm sure I don't have a great strategy, but I am struggling to understand why the significant drop or what I should be doing to reasonably maximize ad revenue.

Your not the only one... I have had the same exact issues, I have been trying to figure out if this is some thing that has to do with Adsense, my server, Xenforo or a combination. I went all the way down to less than a dollar a day revenue after 25 years of successful advertising success. The only thing that changed was that I upgraded to the newest version of PHP and the newest version of Xenforo. According to SEO sites my server is configured almost 100% for all categories so not sure what to do. It's just not sustainable. I can tell you that Google changed the model from CPC to RPM for payment so you don't get paid per click but how many thousands of impressions.
