Argh! Am I being smart priced?
eCPM has halfed from 1st December onwards

 11:56 am on Dec 4, 2006 (gmt 0)

Hi everyone,

For me November was a extremely good month. I was getting EPC in the $2.5 - $3 range, clicks were high, earnings were consistently at record breaking levels - life was good.

1st December rolls round and suddenly EPC drops down to the $1 - $1.5 range, yet traffic and clicks remain about the same (roughly).

What’s going on?!

I can take a look at the website with the preview tool, but the biggest country of visitors, isn't mine, so the tool only gives you an approximation of the ads being displayed. I can ban any known offenders (like ring tone ads etc) but would this just be filling up the filters unnecessarily?

Can you good people offer any suggestions?

Friday, Saturday, Sunday?


 1:08 pm on Dec 4, 2006 (gmt 0)

Could it just be one of those ups and downs? Three days doesn't seem like a long time and it was a Friday, Saturday and Sunday. Those can be very bad days.


 1:46 pm on Dec 4, 2006 (gmt 0)

If you're dealing with any kind of niche subject, weekends can swing all over the place, depending on TV schedules, events in your niche, or even the weather.

My CTR has gone down as well for the first four days of December, but I'm not going to worry about it unless it continues well into the week - and initial indications from this morning are that it won't.


 2:09 pm on Dec 4, 2006 (gmt 0)

Man quit complaining ;~) the best click I ever got was less than $1.50, most are in the .05-10 cent range.

Lovejoy -out


 2:16 pm on Dec 4, 2006 (gmt 0)

"Man quit complaining ;~) "

I second that. You got an excellent EPC.


 2:59 pm on Dec 4, 2006 (gmt 0)

As I understand it, the preview tool doesn't tell you the actual ads showing on your site - only examples of those that are availble to show.

To achieve EPC that you indicate, you must have very well paying ads on you site - I suspect that advertiser are not able to continue funding an unlimited number of clicks at those prices - maybe some have pulled out of the market - to be replace by more ordinary bidders, or possibly some have reduced what they bid.

To average the sort of EPC you state, I'd guess you have only a few diffferent advertisers - one or tow changes by them could make a big difference to your data.

excellent? are you kidding? that's way more than excellent!

I just read this topic in the Adwords section

AdWords: Quality Score Discussion [webmasterworld.com]

I noticed that late november ecpm's went down almost half way.... I feel this is the problem... one reasons google stock is over $500


 4:22 pm on Dec 4, 2006 (gmt 0)

My apologies, I mistakenly typed EPC, when I was actually thinking eCPM.


I'm actually in a low paying area, so I count on quantity of clicks rather than quality of clicks. The site itself is well respected in its associated niche, so I hope that its not a 'quality' scoring issue.

I understand the thing about weekends (and that usually is the case), it was just a bit of a shock when for the last 30 odd days every day was mega (including weekends), then come 1st December, earnings for every day have been halved.

Will have to see what the rest of the week brings, just hope it doesn't carry on!


 6:58 pm on Dec 4, 2006 (gmt 0)

eCPM is an excellent measure for comparisons between different sites or different forms of advertising even.

But it's not very useful when it comes to working out what is changing about a site and why.

eCPM depend on the Click Through Rate and the Earings Per Click.

A reduced CTR could occur due to Ads going off target (as has recently happened to me)

A reduced EPC could be due to smartpricing, changes in advertisers and their bids, or possibly be due to increased traffic spending all the budgets.

Work out what is causing eCPM to reduce in your case and it may help find how to fix it.


 7:31 pm on Dec 4, 2006 (gmt 0)

My CPM went down also 60% those 3 days, i had 80% the clicks i usually have, and is still like that today, i dont know what happened, my site was down for a few hours Sat and Sun, i dont know if that can hurt CPM, instead of a Big Mac, now i can buy small fries.

I hope this gets better.


 8:04 pm on Dec 4, 2006 (gmt 0)

Yes, today and yesterday my eCPM is 50% lower and my niche is stable (3 years experiente).

Is a google experiment going bad :(

Let's see how it goes..


 8:07 pm on Dec 4, 2006 (gmt 0)

our drop wasn't unexpected. we can tell there was a big change. last 2-3 days recovering a little bit but still out a few pennies....

One reason you should never put your sites income ALL IN ONE BASKET


 8:19 pm on Dec 4, 2006 (gmt 0)

What happened to the context vs site ratio? Most of the revenue on my forum comes from site targeted (CPM) ads and revenue generated by this category of ads varies wildly depending on which companies are targeting my site today.

whitenoise - be careful about posting your eCPM, I beleive it's against the Adsense TOS to do so.


 9:32 pm on Dec 4, 2006 (gmt 0)

I wouldn't panic, because when things like:

+ new month starts
+ ...with friday/saturday (low days)
+ Sunday is the first Advent
+ with xmas stress and parties
+ with part of U.S. being without electricity
+ etc etc

...accumulate at the same time some sort of downhill is very likely to occur.


 10:00 pm on Dec 4, 2006 (gmt 0)

My numbers were down the last 3 days - today is better. There was some bad storms in the country, I heard 400,000 people without power in the midwest - so maybe that hurt, holiday shopping too etc.

It happens....


 10:55 am on Dec 5, 2006 (gmt 0)

Thanks for the advice Pengi. My CTR remains about the same, traffic and clicks are slightly down, but not by much. So the only thing I can think of is that advertisers are not bidding as high as they previously were. So while everything remains roughly the same, the bids are probably 50% less than this time last month, consequently my earnings are 50% lower. Nothing I really do about this I guess, just be greatful for the ride ;)

Things are pretty much still the same at the moment, so I can only assume the factors that alephh and Huntster mentioned are also making an impact.

Message to Google : Are you conducting experiments? Please stop! ;)

I noticed that late november ecpm's went down almost half way

I can confirm that. Since November 20, we've had 50% lower eCPM after 6 months of incredibly stable income ($4000 per month). CTR and traffic are the same.


 7:34 pm on Dec 5, 2006 (gmt 0)

Ive also had roughly a 50% drop in cpm, its very frustrating because without some feedback from G,we always end up tweaking somewhat blindly. Adding to blocklist, removing from blocklist. ad placement, run of site ads, banning/unbanning certain ranges in .htaccess.
And SMART pricing. Why would i want the same advertiser again if they are'nt getting conversions? Why cant I be advised who is getting discounts saying they never got enough conversions and let there ads run on someone elses site since my site obviously doesnt work for them. Point being, why advertise on my site again then? Its no good for them or me. They dont get enough conversions, I,m displaying a link to someone i know isn't going to convert well. No thanks. Give me advertisers that are happy with the traffic i bring them, anyone else i do not want on my site. Adsense Advisor, if you're out there any reason this cant be done? Let us know who is getting smartprice discounts so i can add them to my blocklist or better yet some other means of preventing these under-performing ads running again.
On another note i am about to try G analytics. Wouldnt it be good if G advises us who to ban through htaccess etc, since they have better analytical abilities, thus reducing fraudulent clicks and protecting the reputation of the business.


 7:57 pm on Dec 5, 2006 (gmt 0)

the big question is since we are seeing big decreases in our ecpm... by 50%-75%

Did adwords advertisers see their cost per click go down, or is this a new more profitable formula for big "g"

Its nice that G analytics is free, but remember its all in all the same company... just watch out for your bounce rate


 8:32 pm on Dec 5, 2006 (gmt 0)

That is a great post and I only hope that AS Advisor takes it on board.

Indeed, Walrus made good points.


 12:48 am on Dec 6, 2006 (gmt 0)

>>>Why would i want the same advertiser again if they are'nt getting conversions?<<<

because for one thing, their competitive bidding for positioning in your ad blocks will increase your epc... assuming that you have blocked the mfa trash, of course.

if your traffic doesn't convert for an advertiser, it's their job to block your site in their ad campaign... and it's adwords job to provide the advertiser with an accurate method of defining and tracking what a conversion really is... most of us know that are issues with both of the above.

looking at it as a "50% drop in cpm" situation could be part of the problem, because adsense pays by the click, not by ecpm... so if you don't know where your low epc pages are, you won't be able to improve your average epc by removing adsense from pages that it doesn't perform on.


 1:31 am on Dec 6, 2006 (gmt 0)

Thanks Scurramunga and John!

Danimal, guess that makes sense, but when i block all the mfas that i'd like to, i end up with to many psa's, so i unblock a bunch again. Been a bit of a vicous cycle,(figure G's gonna get mad at me and tell me to stop fiddling with it.)

I've read about removing ads from under performing pages before but most low traffic pages get great epc and higher traffic pages get enough clicks that i dont mind the low epc so i'm not sure what to do.


 7:58 am on Dec 6, 2006 (gmt 0)

Murphy's law: just when I got my SERPs up, down goes the revenue.



 9:44 am on Dec 6, 2006 (gmt 0)

just when I got my SERPs up, down goes the revenue.

many have experienced the same, including me.


 10:36 am on Dec 6, 2006 (gmt 0)

Don't feel alone. I know I've been Spriced since November, but I do run a site that is quite seasonal. Once my season comes around I'm "hoping" the higher paying ads will come back. I'm not an Adwords buyer, but if I was I'd do the same and stop my ads on low conversion sites. Walrus seems quite right! Nice post.


 10:41 am on Dec 6, 2006 (gmt 0)

Bit late, but some good points you raised their walrus.

Danimal, I think it's a difficult situation when it comes to removing adsense from low performing pages. I have a large number of pages that have lots of impressions but a terrible CTR. However quantity counts, so while conversion on these pages is low, it still brings in a chunk of revenue. I have experimented with removing adsense from these pages, and sometimes (not always) earnings have gone up. However the problem lies in the fact that you will never know if the increase in earnings (because you removed adsense) is more, less or the same as earnings you would have got from keeping adsense on. There is no way to track this, so how can you know what the best option is?
