Yes. So it's not only me. It started 9th November (QS for content effect?) The ads used to be quite consistent on my homepage which used to be the biggest earner with the highest CTR.

Now lots of low paying ads are appearing, many of them affiliate links. I'll wait and see if the ads go back to some stability. If not, I suppose I have to get used to using the filter list which I hardly used before 9th November.

I'm not seeing this. Same ads, similar perhaps slightly higher EPC....

I've been seeing intermittantly whacky targeting for a few weeks now. I'd see ads that were not mfa's, but just hopelessly wrongly targeted.

It's pretty stable at this precise second though.

With a night's sleep I'm now seeing what is really happening.

Seems like they've made significant changes to the matching of keywords to pages. With marginal results.

If I had page about trials for database use. I'd be getting ads for court room trials.

And if I talked about microsoft access I'd be getting ads for accessing things.

I'm seeing this on the adwords site too.. different ad groups within a campaign are popping to the top of the list based on clicks.

Some adwords people maybe cleared out their negative keyword list in order to get more visitors.

Maybe it will turn out to be good once G has statistics to show better performing ads again.

They are just shuffling the deck.

Any one else noticing a bunch of new ads on their sites?

Yup.. clicks have fallen, CTR has fallen, eCPM and earnings have nearly doubled though. I don't have the slightest clue what they just did but I hope they leave it like it is. I almost love you again Goog.. almost...

My head is spinning.

Overall low ctr/cpm however...

Pages that used to get penny clicks are now getting $ clicks and vice versa.

Any one else noticing a bunch of new ads on their sites?

As accurate as always however my EPC is recovering to "normal".

I'm seeing a regular deep-pockets, branding-minded advertiser all over the place for certain keywords categories, but in fact there was nothing ever wrong with the "regular" smaller advertisers for that niche. Maybe because it's the weekend.

I'm seeing a big change in adsense somewhere around the 6th till the 9th.

- I seem to be getting much better ads, far less scammy in nature
- I get about the double of impressions on adsense.
Now my traffic is up as well, but proportionally I get more impressions, so I think they show less alternate ads (would need to verify much deeper), or they are faster in delivering it to the browser missing less impressions.
- CTR is lower, but eCPM more or less fluctuates within it's normal range, resulting in a very nice increase in the $ amount.
- hence, CPC is up as well (and that I do like a lot) as I hate giving away visitors that are only worth a cent to the advertiser.

But as I said I have an external event causing a significant increase in traffic as well and it more or less started on the same moment as what you report just for adsense, so it's hard to separate the two events.
