pretty simple as to why your earnings dropped. There is more competition for those keywords (from other sites showing the ads) and thus the payout is lower since there is lots of people showing those ads. Also there is not enough advertisers paying more into adsense to help support all these new google adsense users. I am guessing this trend will continue. You are now going to have to bring in more visitors to make up for the lost revenue!
Nov/Dec was about $25/day for me ... now it's about $13/day in January. Same amount of traffic... I see I'm not the only one.
There have been several threads pertaining to the drop in earnings; and yes - I am experiencing it as well.
Not great but hope to get better by getting off the Google SERPs farm with my own custom web browsers. If I can get webmasters to use BigBadBrowser.com to distribute their own web browsers, I can split the ad revenue with them and not depend on SEO, link building, Google, or Yahoo. Would be sweet if it works. May not help with eCPM but at least you can monetize loyal members. My January 2008 earnings seem to be consistent. But the big dropoff came in August 2007. I wonder what happened?
I've got one site that averages 0.02cents/click and is making xxx/month. Doesn't even require a lot of maintenance, but I worked hard at getting traffic a couple months ago and it obviously paid off.
My Adsense has got nailed as well. My link units REALLY suck now...went from around 8-10 cents a click to 1-4 cents...
same with me too my adsense earning really sucks it thought it ll back to normal after christmas but it didnt
with clicks in three figures I am earning less then 25$s per day Previously the earnings were in 50$s area with clicks in 2 figures. New Year till now is not that good for publishers
I hope so it is my first january with adsense is Jan earnings suck usually? first time less than 1 cent per click !!!
December was worst for me, most of my sites gave around 0.01 per click. But it changed back here in January, now I'm getting 0.1-1.5 per click again on almost all my sites. ;-) Anyway it really seems to jump up and down, really weird by the way.
I get almost $.50 per click on one site lol , but on others the rate is between $.02 - $.20 . It depends on your keywords and seo .
