So it's just bad targeting, ad blindness, and financial crisis.

I don't think it is that either; at least not for those of us that have seen a sudden and huge fall in CTR.

My CTR is all over the place! Mostly around 1% but can be .25% either side of that which means I can earn 50% more/less from one day to the next.

Glad I'm freelancing this week!

Today is extremely poor. It couldn't have been more different to yesterday if I tried.

Same here. Abysmal results today.

I've had a click dump since then. Stange thing is, CTR is an awfully low .89% but CPC has gone through the roof - making up for the CTR %

Way off here too.

This October my earnings dropped. I guess the third party ads have something to do with it.

Did you block them, or allow them ?

I never accepted them from the start.
Today started off bloody awful, but by the 13th hour of the adsense day, I had already broken my baseline. And looking at the earnings right now, it looks like I will have my best day ever (or extremely close 2nd)... and the CTR is only 1.1% - way down on normal.
Strange day indeed.

That's good news Lame_Wolf -- I have a few hours left before it's the 14th for AdSense to rally, otherwise it's going to be the lowest earning day in several months.

Thanks Play_Bach. No idea why such a huge increase in CPC. Same adverts that I normally see, although I have not looked all over the site, but nothing out of the ordinary. Extra 1500 visitors a day, but I do not have adsense all over the site, just about 20% of it, and more visitors doesn't always mean more money.

I am puzzled, but pleased :)

Well, alert readers will know all about my earlier "screaming whinges" beginning this year about CTR down to almost zero [I'm now grabbing a piece of wood in the "touch wood context"]. OK I exaggerate somewhat. Actually I'm bloody not.

I can only report excellent results since dropping 728 X 90 "above the fold" in favour of the 330 X whatever - it is a rectangle thingy with large fonts. AND I removed "extraneous" junk nearby. God Bless whoever invented SSI. One file change site wide.

Php people can make their own arrangements.

Geez, I hope I haven't "Jonahed" myself with this post. Income is very, very nicely. NOT 2003 levels [or whatever they were back then] but definitley "nicely, nicely"

I, and I honestly believe this, no one can predict the right AdSense algorithms.

I know for absolute certainty the following:

a) A reduction of CTR since the "good olden days" of where CTR was "anywhere" is CTR is now down to probably a reduction in "hit area".

O.K. a no-brainer and a "free kick".

b) A "possible" nexus of clicks V's EPC. That is, better quality clicks, better quality EPC. I've in a "half baked" way noticed this over a long time. Same impressions, low CTR, low EPC - Same impressions higher CTR, higher EPC!

I can not sincerely give anyone good advice as what to do. AdSense has more "baffling" variables than I've ever encountered anywhere before.

The very usual:
a) FWIW
b) YMMV

No click dump for me :-(

Turned out to be the best day ever for me. (And that's for over 4 years).
Well chuffed :)
