On one of my websites, which according to the adwords pricing tool should be receiving clicks worth $5.00+ (without Google's cut) has received 10 clicks today, totalling $0.12 in revenue. This is a new absolute low for this website, on weekdays it receives about $0.10 per click. I just wish there was some more contextual advertising opportunities, quite frankly im going to jump on MSN or YPN as soon as its released worldwide. Anyone else seeing this sort of downwards trend? Im really not seeing adsense as a viable or reliable revenue source anymore.
Try filtering out some ads that you see that have nothing to do with your niche. I did that and noticed that I was getting higher paying keywords.
