Adsense - 85-90% from July avg
Adx - 100% from July avg

Some positive results so far, better than yesterday. Fingers crossed.

Its better today. We will see.

I am seing super high RPM numbers for the first hour of the day. Almost too good to be true. I am just hoping they have fixed something. Will report back later.

Yesterday finished with a late surge and ended up about 15-20% better than the day before. Still abysmal by normal standards though.

All three of my Gmail inboxes have just been hit with offers for reciprocal-spend Adwords vouchers. Makes me wonder if this was purely and simply caused by a slump in inventory.

I also received Adwords voucher. Maybe it's a compensation for the bug :D

I would agree with you trebuchet. But then I saw a few ads in simplified chinese and other totally unrelated trash. Personal targeting seems to have worked somehwhat ok, but site targeting (inkognito mode) was awful. That much inventory just gone in one single blow would be something alright. Affecting websites in all fields, making all of our coverage drop. Must have been some big advertiser or two if that is the case. Who knows, that might acutally be the case.

Don't know if it affected all markets. One denominator seems to be that the major drop occured on english language sites.

Me too. I also got the AdWords discount voucher from Google Analytics. But the amount is nothing, lol.

Maybe it is their way of filling up inventory :D

It's off to a better start. We'll see how the day goes.

I asked an AdSense employee on Twitter. Here's what he said [twitter.com...]

Somebody on twitter posted a reply they just received from the AdSense team: [mobile.twitter.com...]

Seven hours into the day and it's more of the same, unfortunately.

Some reporting of the CPC plunge here:

[seroundtable.com...]

I am now seeing averts on my sites instead of alternative adverts that I made.

Thanks HereWeGo. Unusual for Adsense to admit a problem. I'm not seeing backup ads anymore, ad quality has improved and RPM is good... so far.

Barry Schwartz just posted on twitter that he reached out to a Google employee and will get an update from them.

Also, just checked and things appear to be 90% recovered today! This is a good sign for everyone.

No major recovery here yet :(

Update: 70% recovered. Some hours left for the day to end so I'm hoping for the best now :D

Well, I think it's a matter of time at this point. Hopefully Barry Schwartz will get a good answer from Google DIRECTLY soon. Once he does, I'll report back here.

Major recovery going on here! RPM is up over 100%. Coverage back to normal!

I wouldn't go as far as saying spectacular, but yesterday was extremely good, into double figures actually.

It seems that one particular responsive unit which is placed either under the heading, or on the the first paragraph is starting to pay off. I made £6.70 p ($8.70) from just three clicks on this responsive unit.

The page RPM was £2.63 and impression RPM £3.11. These are the figures I was seeing when the really good money was coming in for five years ago.

Today has started off quite well so I'm hoping for another good day

Hey, I just wanted to post my experience on this issue. I have been here on the forums on and off all day yesterday trying to find out what the heck was going on. I see some of you saw this drop a few days ago, I didnt start seeing anything weird for my account until yesterday. The weekend was pretty normal, Monday was pretty normal then yesterday BAM! I knew from previous Tuesdays something was wrong as early as 7am. It was way far behind where it normally would be. Definitely saw a drop in earnings by over 50% yesterday. I have seen something similar in the past, but it was a little different this time around. In the past I would start out normal then as the day went on it would slow down to a crawl then by night I would hardly get any clicks, but by the next day everything would be back to normal. Yesterday the main difference was, it started right off the bat and continued all day long. I got fed up trying to figure it out and said the heck with it and just went on and worked on other stuff while this issue ran its course. Now today Im crossing my fingers hoping there was actually an issue and that Google will fix it and things will get back to normal.

But anyway, hope everyone is seeing things get back to normal. Im going to wait until the end of the day before I determine if things are back to normal for me or not. With regards to the money lost yesterday, I will just mark that as a loss and hope for the best. But yeah it was a lot, the biggest drop for a single day in my adsense history.

EPC is still below normal but CTR is up, so overall RPM is good. I'll feel better if/when the EPC comes back up.

It's back, AdSense is almost back! :D Around 10-20% drop and it is acceptable.

Is there a site out there that shows common reports we can run to help determine how good/bod Adsense is running? I understand they have their own documents, but just was wondering if there was a site that provided how tos on learning how to read your adsense data to help better improve etc.

I find [adrevenueindex.ezoic.com...] is pretty good to determine average revenue performance. Notice the big drop sunday :D

@Sillysoft it is difficult for one report to provide a meaningful response to everybody. Basically the dashboard does that, but, as you are noticing it is not fulfilling your specific needs.

Here are some basics that might help you.
The king of all metrics is impression RPM (not Page RPM). Impression RPM shows you how much each 1000 ad impression earns you. It is a standardized figure, and thus allows you to use it to compare value across devices, bid types, day, years month and so on. So say your impression RPM for the past 30 days was $1.00 and your impression RPM for yesterday was $0.50. These numbers are comparable and thus you can see that yesterday was well below average.

The interesting thing is that you can use it compare CPM (cost per 1000 impression ad bids) with CPC (cost per click). If you go to Performance reports> Advanced reports > Bid Types. Then click on the bar chart logo in the top right corner of the chart. You can will see by default the earnings. You likely see that CPC bids have earned you far more than CPM bids. So you think "why waste my time with that crap", You then click on the clicks box (sub-tab) and then see that CPM earned zero clicks. Which should be expected as CPM ads can't be clicked. So you think "What gives?".
But if you click the impression RPM box (sub-tab) you will see the impression RPM for both and now you can compare. In my case I something like a 2:1 difference in RPM. CPC earns me double what CPM does. But this will vary depending on niche and day and other factors.

You can repeat this by comparing other feature, such ad-units, creative sizes and so on. It all depends on what you trying to determine.

A quick note about Page RPM, page RPM is interesting as well but the metric is at the page level, so a page with 2 ads will be biased to a lower value as compared to one with 3 ads. But the interesting thing this is that you can use this metric to see which pages are performing best. Within Adsense the will only really work for you if you are using custom channels or for comparing sites at the page level. But if you have your Analytics account linked to your Adsense then the Publisher Pages report in GA will give you page level data under the column eCPM which is in most case the same as Page RPM (just named differently to confuse people, I guess). Comparing individual pages to the overall value in Adsense will allow you to see which pages are performing best.

I hope this helps, play around, you can't really break anything. If you have any questions post them here and I or someone else more knowledgeable will answer.

Note to Mods: Maybe we should break this out and start a thread Tips and Tricks for using Adsense Data and Reports.

Its a little after 10am here and Im already almost at what I finished with yesterday. So I think its getting back to normal :)

Mine has recovered but only slightly. That could be because the bulk of my traffic in late July/August is Australian, and Australian CPCs have been in the doldrums for 1-2 weeks. RPMs for other traffic sources look OK, I'm just not generating much traffic.

Anyway, hopefully the Adsense phoenix rises from the ashes for everyone today.

I was at a number higher than yesterday's by 8AM and with four clicks. That's how bad yesterday was. Today looks much better.

I am able to report that my today looks pretty much normal now. While I don't write down my numbers hourly each day, I can't compare exactly, but at 11:30am today so far with about 850 ad clicks my total revenue, CPC's, CTR's and RPM look about right. My visitors are almost all US, both display and text ads.

Crossing my fingers that this will keep up.

I doubt any of us will be seeing any recompense for this.
