a major drop in EPC occured

I have seen a major increase from the 22nd onwards in my EPC.

big drop here starting on the 21st,too.

[Annii]

dramatic decrease here starting 21st and getting worse....

[europeforvisitors]

No change here, except that yesterday's EPC was my best since April 1. (It was back up to March levels, which was probably just a fluke.)

[Kimkia]

I've seen a nice recovery, back to pre-April rates, with higher CTR and higher EPC. Ads are highly relevant now, with a huge improvement over the beginning of the month.

An EPC recovery started for me on April 21.

EFV, I've had a good EPC yesterday as well. There are some sites that seem to have similar fortunes in terms of the big turns in tide. Though our IT related sites are on a subject widely different to yours they seem to generally mirror what's happening on your site, whether it's on earnings, targeting or PSAs.

I have another smaller site that is seeing the same 21/04 problem posted here. In fact that site has mirrored the same rise and fall in fortunes as some of the other posters here.

Anybody for a theory that there are two major categories in Adsense?

[Annii]

Here's what's different for me:
I introduced channels to my ads.
Earnings per click have dropped most dramatically on 1 particular site (by almost 80%) since 21st April.

Here's what's the same:
Targeted content
Relevant ads (as far as I can tell - I can only see UK targeting.... anyone know if there's a way to see what is seen by a US visitor?)
Impressions (this one site gets about 3000-5000 per day)
Click through ratios

Any ideas what it could be?

[moftary]

In my case I have noticed this major EPC drop while preserving the same CTR, targeted ads and no PSAs.

I have checked Ads on my site(s) from where I live in Egypt, and from my dedicated server in Texas, US - no difference.

That might be an idea for annii on checking Ads from outside, AFAIK, there is no other way.

Regarding the problem, I can guess that Google has implemented a new technique that caused this major drop in EPC for some of us and caused also the 23th of April PSA disaster.

[JinxBoy]

More EPC for me...

[keypclkn]

Day 6 - still tons of PSA ads [ that dilute ctr].

EPC is decent but # of clicks is small.

<snip>

Anyone else still serving lots of PSA's on important pages? [ high PR, updated daily, many backward links from sites with similar content]

Thanks because Im sweating it out here.

Yep saw exactly the same, clicks static, impressions static, earning way down since 21st (approx 60% drop). Up until the 21st April had been our best month, we saw a massive increase in revenue at the beginning of the month when others saw a drop. We're in the UK.

We're in UK also and more or less the same experience as you. Excellent month up until around 21st. then all sorts going on.

I'm just a Google toy
A little part of the big ploy
They toss me up and down and round
I hope they dont miss...
It hurts to hit the ground

fasteddie:
our experience has been just like yours

[icedowl]

In my case I have noticed this major EPC drop while preserving the same CTR, targeted ads and no PSAs.

Ditto.

An indicator of ongoing results and tweaking from 'black thursday'? I wonder if adwords advertisers are now seeing the cost reduction.

[Never_again]

EPC has be rock steady all year.

Now, if my math is correct, there have only been four working days since the 21st. Certainly not long enough to establish a trend. Wait a couple of weeks that then post your results.

[ScottM]

EPC has gone back to pre-April. Looks good on my part for the past couple of days!

[valeyard]

My figures continue to swing wildy, neither much better or worse in the last few days.

Annii:
To view your site as people in another country would, set your browser to use a proxy server in that country. There are lists of these around. I'm probably not allowed to post a link so do a Google search for "public proxy server"

My US ads tend to be a lot better targetted than my UK ones, possibly because there are more advertisers.

My EPC is way up, going to buy Mercedes S600 2004 soon... :)

[creative craig]

I am on target for the Mercedes SL55 AMG :)
