Why my sites have more unique visitors and the pageviews + Clicks increase 20-30% but the revenue decrease 20%. With that total clicks 1 month ago, I would get 60-70$ dollars but now I only get around 30-40$ I need your help to increase the revenue please, the source of traffic is still from SE and USA region
It might be due to running different ads on your sites. Adsense earning also depends on running ads and click ads. Some ads offers more earning while some less. In festival seasons, number of advertisers advertise their services and due to this more payable ads run while in off seasons less revenue ads.
If this revenue fall happened in the same blog, as you said, then maybe its Google AdSense smart pricing enforced on your blog. If the clicks in your blog aren't converting for the advertiser, Google may enforce smart pricing. Click values will decrease considerably. Other reasons, maybe you have changed your ad dimensions, colors or position on the page. Such changes can alter the revenue generation. Did you check if your blog is getting relevant ads or not? Revenue may fall in that case as well.
I don't know how strong your key words are? You should select such keywords which have good Estimated Avg. CPC. You can watch it from Adwords key tool. Placement of ad is also important. You may take help from Google support center for the right placement of Ad.
There are many things that can happen. Advertisers don't always pay the same amount for clicks and because of this the CPC you get can be seasonal - this is the most probably thing that happens. If you were smart priced, you would get only $0.05 and similar clicks.
my site is flash game and the Avg per click around 5 cents. but now it decrease below 5 cents per click. average traffic was 2k unique visitor (google analytics) , now 3k unique visitor and the click increase up to 1k5 clicks per day but earning is around 40$ daily...... Visitor come from mainly 80-90% from USA (CA, TX)
I think the ad publisher on your niche are paying low amount for their ad and that's why you are getting low revenue
