Is anyone seeing a drop in Earning per Click?

Our EPC tends to be fairly stable with about a 10% variation from day to day. Broadmatching made it go up a bit for a day or two. But over the last 3 days it's dropped by about 50% from the previous norm.

I've checked all my sites and it seems none of them have been down. I've excluded factors like weekend etc as I'm comparing with similar periods in the past. It's not the end of the month, so it can't be budgets. My impressions and CTR are normal so it can't be the IE problem and/or ads not being seen by visitors. But I've "lost" a three digit sum so far as a result of this reduced EPC.

I know it's a small sample and all that but our daily clicks are in the decent three-digits - so not that small a sample.

Anybody else noticed a drop in EPC?

I have seen a drop of 40% since the beginning of the month as well.

Don't know the reason ...

I cannot say that I have noticed a change, but then again I have been changing my pages a lot to be more google friendly.

One thing that I have noticed is with this broad matching there is not the same subject relevance.

By example a page that talks about cleaning a home would now show many more ads about home loans than cleaning.

The broad matching could therefore give you a reduced CTR but on that same note you could see an increased or decreased CPC due to the new variety of ads being shown. It all depends which way the cookie is crumbling.

Maybe this is why google is keeping us in the dark with CPC and limited reporting. Once all these trials have been dealt with they might start letting us know what is going on

I've been charting EPC over the last 6 weeks or so, for a site that gets roughly 25000 impressions/day. The minimum EPC has remained constant, with variations up to 4X the minimum, and an average of about 2X. The number of clicks that the site generates is relatively stable, but because of the big variations in EPC, daily earnings are also quite variable (although they are relatively stable on a 7-day average basis).

Up until a few days ago, the overall trend for EPC had definitely been downward. However, that seems to have reversed now, at least temporarily.

Sense_able, nope not seeing a reduced CTR. Perhaps the less contextual ads they are serving are also lower priced.

Sharky, I must admit that over a 7 day period it works out OK - about average. I suppose the good start to the week kinda had me fooled. I wasn't expecting that they'd drop my earnings to make sure the average per week was maintained ;-) Seriously, though I think you may have a point there. Maybe they do try to ensure the average per week does not go up too fast.

You do seem to have much higher variation on EPC: 1X to 4X. Mine tended to be much, much tighter. Perhaps that's why this drop is so much more noticeable.

Not disclosing numbers, but as an overall comment, yes.

I have a spreadsheet with CTR, CPM after CPC, EPC and I've noticed a little drop in EPC (consequently CPM). The CTR is constant for my site and impressions in the last three weeks went up a little (thanks to some articles I've posted that attracted lots of readers).

"Saturdays suck" --- not to mention that it's a long 3-day holiday weekend in the US and Canada. Our impressions and earnings are way down.

I recommend charting a 7 day running average. That will filter out the variations that should be expected over the course of a week.

since last week my earnings have been $20 lower on a daily avg. this new thing google is doing is no good to my per click avg, i have almost exactly the same number of clicks everyday.. i see ads less targeted as well...

Nope. Last three days have been right on target (=/- 5%) for my average CPC.

As for weekends, for some reason Sundays are great days for my sites... who knew?

OK, thanks for your replies guys.

To summarise it seems that the drop is not universal - not everybody who's posted here has admitted a drop. That's what I was trying to establish.

Also, I was not aware that it was a long weekend in North America (though that would affect mainly the impressions and consequently the click-throughs ...but not the EPC).

I hope it gets better this week for ALL of you :-)

I see the same. My take on the matter is that for the last 2-2 1/2 weeks, Google has been using an older index that has fewer of my pages indexed, so that is, I believe, why I'm off by about 1/3rd.

Things were great up to October 8, but there was 45% drop starting Oct 9. The earnings have been consistently low since then.

My earnings are also low... but this is usual for me... :(
However, I intend to place the google code on some password restricted pages also. This way I will have a lot more impressions.
Is there an easy way to let search engines to spider my password protected pages? If I have a list of IPs that are used by search engines, I can simply code the site to not ask for username and password on restricted pages if the IP address is in a certain range. Any pros / contras on this change? Is this advised?

I saw a drop in CTR (about 20-30% drop) starting Oct. 9th, along with a drop in impressions.

There is something odd going on.

Also, I was not aware that it was a long weekend in North America (though that would affect mainly the impressions and consequently the click-throughs ...but not the EPC).

A long weekend could result in lower payments per click if advertisers suspended their ads for the weekend, or if advertisers with a day-trader mentality went to the beach instead of bidding.

In any case, I think it's hard to discern trends on the basis of limited experience and anecdotal evidence. There are just too many variables. Take my category, European travel: As we get into the low travel season, demand (and therefore bids) are almost certain to drop for some destinations, products, and services; but in some cases, demand and bids may go up. Who can say, for example, that hotel demand in Venice during Carnival or in Switzerland during the ski season won't offset the off-season drop in demand for Eurailpasses and camper rentals? Experience with affiliate sales may provide some guidance, but only some, because AdSense can provide targeted ads for so many topics that affiliate programs don't address--e.g., Greek yacht rentals, mail-order alphorns (the ideal Christmas gift for the adventurous tuba player), or naturist resorts in Croatia. Even if advertisers' bids stayed the same, seasonal changes in user demand (a.k.a. the "look-to-book ratio") would affect revenues and effective CPM.

We are seeing some of the items others have been noticing in the past few days. Have to think something has happened due to "broad" matching affecting what we are seeing.

One thing for sure this month will have to pick up substantially to fit the averages of previous months. It is still early, with all the changes, but will have to monitor it over the next few weeks.

With the number of posts on this, would have to think there is an underlying reason somewhere?

Aha, more people with the reduced EPC problem.

Things were great up to October 8, but there was 45% drop starting Oct 9

I saw a drop in CTR (about 20-30% drop) starting Oct. 9th

My original post said that my EPC had dropped by about 50% - and that was from about Oct 9. OK, with the Adsense user base being as big as it is there is always the possibility that it's a coincidence that someone else is experiencing similar figures to mine.

A long weekend could result in lower payments per click if advertisers suspended their ads for the weekend
. Good point. CTR may still hold steady if lower priced ads are used instead. We'll see how the rest of the week pans out. Not looking good so far though.

Unlike vacations and travel our field tends to be very stable through the year in terms of ad spend (obviously that history for ADSENSE adspend is not available). And we benefit from not having too many variables.

One thing for sure this month will have to pick up substantially to fit the averages of previous months

I agree.

My earnings at the end of the day are up about 20-30% since the start of the month, but my CTR is all over the map on any given day.

>> CTR is all over the map on any given day.

Clicks and impressions usually come through out of sync.

I would hazzard a guess that clicks are being washed through their fraud algo hence delayed,whilst impressions are more likely to go straight onto your stats.

Hence CTR all over the map on a given day

I hope so. The truth is that yesterday I posted a scoop on a new product, and got listed in many other websites.

As a result I had 25,000 pages served from my site in the last 24 hours, instead of the usual ~10,000.

My CTR is the same as before, my impressions are up accordingly, but my EPC are 50% from the previous day.

I manage to increase the impressions ~130% and the EPC is 50% from a day before? :(

Ever since October started my EPC has been horrible, and my impressions have been a bit lower despite my webstats showing no decline in pageviews...

Something is definitely changing here.. I don't know if the cost of ads is going down or what, but for me there's a fairly distinct point where earnings drop off... it's sort of unnerving considering I was close to getting a check every month, and if things remain this way I'll be lucky to get one every 3... :(

Perhaps one of the others who are familiar with adwords might comment on the effect of broad matching starting up this month and the fixes applied by google on the 10th. Have to think we are seeing a side effect of this happening, at least in certain areas.

Last month it was high numbers of PSA's...this month seems to be replaced with lowing earnings in EPC. Have to think they got the ads serving improved through broad matching but getting lower paying ads as a result.

The seven day running average for my EPC has been very stable since the beginning of August (when I started Adsense), with a variations well under +/- 20%. This month seems no different to before, seven day average is the same as current long term average most days, with a reasonable sample size.

Day to day of course the figures are all over the place (3:1 ratio between best and worst) , although again nothing unusual recently. One reason could be my pages are very stable (no new pages).

I would hazzard a guess that clicks are being washed through their fraud algo hence delayed,whilst impressions are more likely to go straight onto your stats.

It looks the other way round to me, impressions lagging clicks as CTR drops during the day. CTR starts very high for the first 1000 or two impressions each day then goes downhill - can't just be click-happy people awake in Asia (start of PST day) and non-clickers in the US (later in PST day). My main audience is US, Canada and UK.

robho...agree with your statements until the last few days. Has been like a rock on a wider average, however have seen some of what is commented on above in this thread, especially in lower EPC last few days. Have not seen this throughout the time we have been tracking (3 months). Accounting for normal ups and downs, it is now approaching the lower limits set.

On top of that we saw a minor shift in ads served in the last few days, both in numbers (not full sets) and some lack in targetting. That's the basis of my "broad change" question above.

Another possible answer to the "mysterious" drop in EPC is that the big advertisers are perhaps opting out of having their ads shown on content based sites and are instead just showing them with the Google SERP's. Why do I say this? Well, it is likely that a BIG advertiser is aware of how well their ads are doing and where they are doing well. If their ads are NOT doing well on Adsense sites then they opt out. Small fry advertisers, on the other hand, may not be as "up" with things and may not realise that they are getting worse ROI on Adsense sites. Smaller advertisers tend to have smaller bids than larger advertisers too..thus more "cheap" ads are being shown and therefore your EPC is lower...Just an opinion here :)

Twiggy, I concur that something seems to be changing.

Some are still experiencing stable 7-day averages; I understand the point of looking at earnings over a longer time period as daily variations can be caused by a large number of factors.

However, I still believe that something has changed. I would appreciate if those of you not having any drop come back in a week to confirm that the 7-day average is still within normal variance of what you have experienced so far.

Seven day average is up over my last 62 day average about 15% in fact.
