I think talking about adsense earning is allowed so I want to share you my observation these couple of days with my adsense account...

I usually receives around $15 to $25 daily but yesterday is my worst... I got $0.98 for 23 clicks and I don't know what is happening... anyone can explain?

people no longer want to go to your site.....?

No, my site is a forum and the clicks are not only coming from one site... I have 5 sites sharing with my adsense account...

Your comment is too far and is out of topic...

Seems like Adwordtisers pay less for the keywords and keyphrases your website is about.
Keyword prices (bids) are highly dynamic, I suggest that you just wait.

you were smartpriced, go to http://www.adsblacklist.com/ , find lowpaying sites and put the list in adsense competitive ad filter. Than wait for 3-4 days

Adsence will observe our account anytime so they can choose you the lower price.

Agreed. Low conversion leads to smart pricing.

how long have you been running the sites?
and if the keywords for each page keep changing,

you need some time to let it sink in,
not to mention the usually compare the number of clicks with page impressions,

if your clicks are high,
and your page impressions are low,

they'd probably give you a lower cpc,
but sometimes,

it depends on your keywords and how much bidders bid for it,
heck, i even had a $1.50 per click ad before,

but my pages keep changing keywords so they fall gradually through time,
that is why Adsense prefer Family sites,

rather than dynamic sites that keep on changing their content and keywords over time,
for people that have sites that have circulating contents,

it's best to settle for your OWN ads,
like TG having their own banner ads,

sorry admin if that offended you,
never take adsense as your main Income,

take it as a side income focus on what you do,
and Never loose track of your main goal when you started the site,

as i seem to find alot of sites that driven solely on adsense,
which is bad to my opinion,

cheers mate.

I have 5 sites sharing in the same adsense account and my CTR is 1 to 3% (pretty fair)...

oh, that pretty good considering it's 5 forums,
and it's around 1% wow you must have like 10k impressions...

imagine the Chng Chng~ $$
