I've heard a lot of people complaining of decreasing (sometimes dramatically) Adsense earnings over the last two months since May 1. Wondering if anyone else on here has been seeing anything similar?

I have not noticed this. The site is still getting the same amount of traffic each day, and the payment seems to be flat. Granted... it was climbing for a while, but it was in direct relation to the number of visitors. My impressions have also flattened out a bit, so driving fresh visitors to the site will help pull me out of this rut.

Granted... I am not pulling in the big triple digits some claim to be getting, so Im not sure how it looks in those situations.

Yes, it seems to be the people who are affected are the most vocal about it from what I've read. Guess not to many people have been affected though (or aren't making enough to notice a difference)

Im down to 75,000 impressions per month from 113,000 last winter. In the winter I usually see a spike. This might be what people are complaining about. I think when the weather is bad, people tend to do a lot more browsing rather than hanging out outside and enjoying the sun. I see this trend every year. My impressions are a roller coaster. You cant judge the earnings on a monthly basis. You really need to view them on a anual average to see if you are starting to drop off.

They need to shut their eyes, take a deep breath, and ride the dips out. It always returns just like the stock market.
