Anyone noticed a HUGE plunge in CTR?

I know a bad day isn't a trend... but is anyone seeing the same plunge? My CTR dropped by 32%. Could this be the PSA plague?

80% drop in CTR compared to a 6 month average. Lowest CTR for a single day.

That said, I don't think it means much. One day does not a trend make. Ads are as targeted as ever :o

Wide swings are normal. I worry more when I get an exceptionally high day, since I don't want my site to get undue attention.

I've seen a drastic drop. Part of that is probably because some sites/pages have been neglected, they need some updating and attention, restored, better and more rankings, while for other pages the traffic has taken a big jump but those aren't the type of pages on which people would be inclined to click on the ads displayed. It isn't because the ads aren't targeted correctly, they would just appeal to a different crowd.

If I removed the pages that aren't likely to generate clicks from the AdSense program and did something else with them, the total impressions would drop right now but the CTR would improve, actually giving a more accurate picture.

No, my CTR is up today, and my EPC is the highest it's been since April 1 (it's back at March levels).

Still, as Willyb. says, "One day does not a trend make."

Marcia, i did just that a week ago. After employing channels I found that my photo gallery pages were generating a whopping 0% ctr. I dropped about 400 pages and had 3 record days immediately following. Total daily revenue from the day I made the switch is double what it was the rest of April. It's like Google was saying "You're using channels, you know what's happening, lose the dead wood and stop wasting our precious servers and you will be rewarded."

What is "employing channels"? I'm wondering because I think I was majorly penalized by the search engines when I added a yahoo-like directory as www.myhomepage.com/index?viewpage=1. I have around 1000 pages of these viewpages which are simply directories. Are my directories considered channels? On around 20 pages I have outbound links with sites I've reciprocated links but the remaining 980 directories there are no outbound links. Could this be the cause of my penalization? I notice that when I create a new viewpage (i.e. directory) the pagerank is immediate and the same as the other viewpages thus I'm assuming google sees this as all one page. I'm thinking of discarding the other pages which have no outbound links and see what happens. Any feedback would be appreciated.

To find out the particulars about channels, just go to the AdSense Help page - there's a link to the Channels FAQ.

I'm sorry, but this makes no sense to me. If your total combined revenue of all pages was (let's say) $1000 and you removed all the pages that contributed nothing to the total, then the total still has to be $1000. That's like saying that you had one store that generated $1000 in sales and one that generated zero sales, and that closing the zero sales store caused the first store to double in sales.

On the other hand, if this can be proven then are you saying that Google reduces our payment if we publish too many dead pages? Or is your theory that we somehow get better ads if we don't show as many ineffective ones?

I believe your stats but I'd really like to understand what's really happening.

I think that may have something to do with it. On the other hand things have been screwy this month so its hard to tell what caused it. All the same, I do plan on keeping things lean from now on. If everyone did that we'd probably all do better in the long run due to a lack of fatigue (ad).

Perhaps if potentially high CTR ads for a site are also present on lots of pages where the CTR is very low, then the new algorithm won't be giving such a high CPC to them and might reduce the number of them as well. So if you remove the 'dead' pages, the algo sees the true CTR, increases your CPC and number of 'good' adverts accordingly?

whats an average click through rate on adsense? 5, 10, 20, 30, 40 %? More? Just wondering because you guys are discussing CTR's changes that are higher than my total CTR any day. Could I be making more? Am I doing something wrong? I thought I was doing pretty good.

I've given up analyzing AdSense anymore. It can just lead to confusion and heartache.

When Google first rolled out their changes on 4/1, I noticed absolutely no changes in my EPC or CTR while everyone else seemed to be complaining.

Then, on the exact same day that the post here was put up about "record AdSense revenue", I watched my earnings decline by around 1/3 or so. And along with it came some crappy ads to boot, too. This lasted for about 2 weeks.

Then, the last few days, CTR and EPC have all rebounded to early April and March levels. And Sunday was a record as far as CTR goes - way above the normal (although not hopefully too far so as to excite the people at Google unnecsssarily!) - and with a very nice EPC, too.

Jim, i had exactly the same run as you.... Yesterday was one of my best days ever, when those other days on which others got great best days, i had very low EPC.

Totally agree on the lean thing, I believe it might have some form of cumulative effect.

1. Less impressions higher CTR...possibly only the higher paying ads get shown

2. Better CTR and possibly improved conversions due to higher quality ads, leads to better ads...which leads to better conversions.....which leads to better ads.

The real unknown of course is how to influence the conversions on the target sites. The key maybe to really make an in depth assesment of sites who's ads your showing. Determine whether or not they are likely to produce a reasonable conversion rate and edit your url block accordingly.

One reason why I think the url block is limited is that if everyone were to start being very selective over the ads they show then, the publishers would start to control the market.

My CTR has been on the slide for a couple of weeks consistently - couldn't see why at first. Then I realised two effects were at work:

1) ad targeting is way off - on most of my major pages about a certain European country, ads were consistently for a different country's capital city (not mentioned on the page) or for various US cities (not mentioned on the page).

2) so when I blocked those ads, Adsense has failed to be able to supply more than two ads in the four ad skyscraper on my homepage for three full days.

It would be less strange if Adsense couldn't find an ad for a particularly obscure page, or for a particularly deep page, or for a short period of time. But when it's the homepage of a site that's very clearly branded on one major topic that's got plenty of ad inventory, it's somewhat frustrating.

It would be great if you could state your site's main topic in Adsense and have it hand verified by the Adsense team so that they could tie in adverts that were only on that topic. Or even better to state the topic by channel. If I've got an advert for a property that talks about its features, I want Adsense ads for other properties for sale or rent or attractions in the surrounding area, not adverts for garden sheds, staircases and laminate flooring.
