How is your EPC since the new Adwords change?

My statistics show a definite downward trend.

So, we are 10 days into this "new" system therefore I now have plenty of statistics to make comparisons.

Yes, it's near the end of the month however history shows my sites are not affected by such advertising dips...well, I hope they're not going to start doing this now!

My statistics are showing thus since the Adwords change:

Header EPC: -7.230%
AdLinks EPC: -13.058%
Overall EPC: -9.922%

Some AdLink days have been quite extraordinary with extremely poor earnings, on Friday my overall earnings were 30.58% less than Thurday with the same amount of clicks, both the header and Adlinks were down, for instance:

Site 1 Adlinks Friday -39.40%
Site 2 Adlinks Friday -26.74%

I've never seen Adlinks earnings vary so much, until now they have been usually pretty consistent however there definitely seems to be an overall downward trend.

Is anyone else seeing similar figures?

Reading through the AdWords forum doesn't exactly fill me with confidence that many understand what is occurring and how to get to grips with it.

In last two weeks my AdSense earnings are record high.

Most of my clicks are low, up to $0.05 per click, but I get good number of clicks that are valued around $1 and then my results are pretty nice at the end of the day.

You asked about EPC.

Ours over three sites and 161,938 page views is up 14.9%.

What we find surprising is that our CTR has fallen 11.5%.

I believe that this could be caused by a lack of inventory while advertisers adjust minimum bids. If they are showing the same ads to every page view then it would affect CTR. Coupled with this is the new AS program to only show one or two ads in a 4 ad ad block.

Whatever the reason - lack of inventory, poor relevance - the CTR is definitely lower.

Glad that the EPC is higher.

I just went back and checked the numbers just for Ad Links.

EPC up 15.2%.

CTR down 14%

These numbers are compared from Aug. 1 - 16 as against Aug. 17 - 27.

For the same two periods that Tropical Island mentioned, my CTR is up 3% and EPC down 3%. So effective CPM is stable.

I do however see much more weird days--both positive and negative--in the second half of this month. This is probably caused by keywords getting disabled and enabled again and advertisers playing with their keyword bid values to keep them running.

I haven't noticed any drop in EPC. (Yesterday I had what may have been the highest EPC since smart pricing was introduced, and my EPC in general is higher than it was a few months ago.)

I have experienced a slight drop in eCPM since August 19, mostly because the average daily CTR is down about 15%. Whether that's due to changes in ad targeting, the number of ads being served in my leaderboards, or seasonal factors is impossible to say. (Late August is a time when many people are on vacation or returning to their universities, so my audience could be in flux right now.)

I can barely make sense out of my numbers since the 15th, but my total earnings are up quite a bit.

EPC is apparently more meaningless than ever once they start mixing CPM ads in.

On sections where I have both Adlinks and regular ads and track them using seperate channels for each, Adlinks is more than holding it's own.
