Just wondering if Anyone else noticing a sharp decline in overhaul Adsense performance.

Jan was my record month with earnings well into three figures per day.
I am notice a sharp decline on all fronts since the beginning of Feb.

Page impressions are right on daily average target (+-5%) while CTR is down by approx 1.2% and “effective CPM” is down by almost 40%.

I have a network of sites (7 sites) on a wide range of topics. The traffic on the sites hasn’t changed much since the begining of Feb +- same number of daily viewers across the network , while earnings continue to slide daily (adsense alone, other aff products i have linked continue to sell well).

I did notice very poor ad targeting on a few pages recently. Pages which used to display very good targeted ads and this may explain the bad CTR and “effective CPM”.

Is there any major adsense update going on?….anyone else noticing this happening since the start of Feb?

I did not update any of my content recently to warrent such update.

Maybe this helps to explain?

Market Watch notes double digit drop in price of ads this quarter, while downgrading Google and Yahoo stocks.

Well that's not very encouraging. But I suppose it might help explain what the deal is.

Price of ads is not as important as how many they sell (get clicked). Earnings are they key. They could have the same number of highing paying ads, but if more lower paid ads appear (meaning higher overall ad volume), the average is going to drop, but this will increase revenue.

Overall averages may be important to someone who's keeping statistics, but they don't necessarily have an impact on the individual. What matters is the average price of the ads that appear on your site.

Agree with Dark and EfV however this thread some 400 :) posts ago started with looking for a change. The above posting clearly finds a reason for dropping revenues across a broad spectrum of the adsense network. Ad prices drop...cost per click down. Google will be feeling the pressure this quarter to keep stock watchers happy with expected growth in revenue and profit. Not much they can do with revenue (market controlled) but profit is another story.

Well, I expect this to be MY last post to this epic thread, at the risk of returning to the original topic of this thread. As you may recall, I was one of the early reporters of pathetic PPC and CPM. Around Feb 2 the decline in PPC started, and eventually bottomed out at around 42% off Jan AVERAGES around the center of this month. Well what a roller coaster this has been. Beginning last weekend and strengthening to the point of a real recognizable trend THIS weekend and this Monday morning we are now back to about 95% of our prior Jan PPC, and CPM and CTR are at new all time highs! Based on 1/3 day of data I'm anticipating an all time high earnings day.
Some continue to insist this is just a "natural" advertiser/rates/randomly driven phenomena. I find the sharpness of the changes, the simultaneous changes in CTR and PPC and the fact that the large moves consistently seem to start on Friday or Saturday hard to construe as a "random event". I still feel that what we have seen is the result of a, probably still ongoing, set of manual adjustments and/or experiments in algorithm changes by G whose most apparent results were to cause wide fluctuations in stats. A benefit, at least to me, seems to be a massive reduction in traffic sucking (scraper) and affiliate ads.
We prviously had over 180 URLs filtered. We are now down to about a dozen and none of the old off topic and cr@ppy ads have returned yet. This algo change seems to have acted like revving a car engine that had been abused or sitting too long to "blow out" the buildup of deposits. I just hope next time they decide to do it, it doesn't impact our earnings as drastically.

My EPC was down noticeably on Friday. CTR was also a bit lower than usual, and effective CPM was only 79% of my average for February. It was my worst day of the month (not terrible, but not good, either).

Then, like you, I had a great weekend. EPC, CTR, and effective CPM have received a nice boost, with CTR being especially high in the last 2-1/2 days. Maybe ad targeting has improved?

Mike, earnings here have normalized as well, my feeling is that targeting was somehow off during late jan and early feb and they have been working on a fix that came into effect around the end of the 2nd week of this feb.

It would be nice if we could somehow accumulare statistics to support such statements. Right now it's just a trend that most of us seem to detect.

Does anyone know if this is typical for this time of year. I would imaging that Christmas has a good 2 or 3 month build up, so that would have inflated the money being spent on ads. Then sales in January.

It would seem Feb would be the month to expect a drop down again, but this is just my logic talking, is that a statistic?

I think the internet has had a good run of profiting from marketing. I don't see that trend as continuing as strongly as it has, although of course I would like it to.

I've pulled AdSense from about 75% of my digital properties, so I guess I can't really comment accurately on whether there has been a drop for me.

The one big drop I did notice was with the last Google update, and I find it very very ironic that this thread was started not even 2 days after that update. That last update plummeted my revenue from AdSense by about 50%, and even though the extra income is nice, I think until it performs like it did before, it's just a waste of space to my users and so it's been pulled.

Like Google say, do what's good for visitors... for me in this case it meant pulling AdSense because the disadvantages outweighed the advantages.

This has definitely been a strange month. For the first week all the strangeness was 100% externally caused. The whole month gave lots of ups and downs, quite a few of which were a direct result of my own tinkering after that first week. A site redesign launched on the 8th, followed by much dinking around with ad styles (size, colors, locations), and many pages of newly added original content have all contributed to the wild ride.

Overall, this month has been my best month since I began using Adsense a year ago. Definitely an E-Ticket ride however. I'm still waiting for targeting to recover from the site redesign, but it's slowly getting there.

Depends on the topic. Traffic and revenues for my travel-planning site drop late in the year (when consumer widget sites are going like gangbusters), then pick up dramatically after the first of the year and remain strong into October. That makes sense, when you consider that most European leisure travel (other than skiing) takes place from spring through fall.

BTW, I've had the same basic traffic pattern since 1997, with only slight changes. (The dropoff occurs later than it used to, and peaks and valleys have become less extreme in the past few years. Also, revenues are stronger in the off-season with AdSense than they are with affiliate sales.)

I just wanted to report that my earnings FINALLY seem to have normalized to about 90%, after being down to 40%-60% for most of february....

The decline starting February brought me to 3 major actions

1.) URL filter now filled with 80 domains
2.) change of colors for the ads
3.) Improved code to improve ads targeting

Each action brought an improvement, despite only 28 days, February is my highest paying AdSense month.

So the niche that my site is in, February is the busiest month of my year. The last week in February is the busiest, as people rush to meet a deadline. Advertising rates go up across the board, as advertisers try and reach people making that last minute deadline. What did I see on AdSense? Some days my EPC was triple what it normally is (this would be expected for this time of year for my site) and sometimes it was 1/5th of what it normally is (totally abnormal for this time of year).

I hope next year Google chooses March or April (which will not be busy for me) to experiment with things, and let Feb. run its course -- I had mostly good days, but there were 3-4 days where the results were totally anomolous: radically lower than the days before and after at a time when they should have been radically higher than normal CTR's.

As an advertiser I can confirm that rates went up at that time in AdWords, as expected, so I dunno what happened. Certainly none of my ads were making it into the top spots, as others were outbidding me on the same keywords that should appear on my site.
