AdSense パブリッシャーの間で懸念されている別のトピックがあります。多くのブログでページ CTR が劇的に低下しており、それが直接的に日々の収益に影響を与えているようです。

先月、上位の収益を上げるブロガー数人がこれを私に伝えてきましたが、私はそれが何かの holiday 前の広告による一時的な変動だと考えて無視していました。通常、10 月と 11 月は一年で最も低い時期ですが、それはブログのニッチにもよります。

この下落は、直近の月と比較してページCTRを最大40〜60%低下させる影響を及ぼしており、結果として日次収益のおよそ半分が失われています。私の管理するブログの一つでも、CTRに突然劇的な下落が見られました。具体的な数値は共有できませんが、この下落と減少したCTRの一貫性は、単なる偶然の可能性をほぼ排除しています。

これは、AdSenseが広告のクリック可能な領域を縮小したという最近の変更による直接的な影響でしょうか。おそらくそうでしょう。これが永続的な効果をもたらすのでしょうか。 hopefully ではありませんが、傾向はそれを示唆しています。

他にもこの現象を経験している方はいますか？

My ctr is 0 from two month I linked analytics to adsense. They are linked now. What a horrible experience. Glad I am not the only one seeing this happen. My impressions and clicks are 0 earnings . Doesn’t make any sense

I discovered that my CTR dropped exactly in november/december 2007. It never got back up again in all these years. What about you? Do you have any explanation?

Mike · 18 years ago

My ctr dropped 2 days ago about 80%, the same day I linked analytics to adsense. They are d-linked now. What a horrible experience. Glad I am not the only one seeing this happen. My impressions and clicks are up but earnings down. Doesn’t make any sense.

Same experience having a big drop on CTR this December. Experimented on many things like using manage ads, not using manage ads changed ads colors, etc. I’m not sure if the reduced clickable area is the culprit because when it was implemented my CTR is still normal. The worst lowering of CTR and eCPM happened during the third week of December until the now.

Also wondering why when my PR increased on my other site on the recent update, the traffic decreased and also the CTR.

There’s no change in my PR but my CTR dropped to 40%

Alfie · 19 years ago

Yep slightly lower CTR but slightly hight eCPM.

Harrison · 19 years ago

My CTR, CPM and also revenue have dropped. However, my traffic also slightly lower compare to last few months. Maybe most of my visitors spend their time on their Christmas preparation rather than sit in front the computer and read my blog. :)

Connie · 19 years ago

I’m getting a dramatic high. Higher CTR; higher eCPM.

leo · 19 years ago

my CTR is slightly lower but the CPM dropped significantly, and to make the matter worse, the dollar is still on a freefall against peso.

otoy · 19 years ago

earnings dropped by almost 30% last november. But the way December started looks very promising.. sana tuloy tuloy na :)

Kiven · 19 years ago

same CTR. higher eCPM.

Mr.Pinoy · 19 years ago

Im still new in blogging but im using Adsense too. If Yuga is correct, I hope it will back to its normal CTR conversion soon.

noemi · 19 years ago

Mine dropped on October-November but it’s picking up this December.

Agree with you bro! iâ€™m also experiencing drop in my adsense CRT…

eric · 19 years ago

my CTR dropped for oct-nov. but december looks very promising.

boddah · 19 years ago

no effects on my sites too, in fact my CTRs for November is actually higher than previous months.. and i thought most clicks from my sites are accidental ^_^

marhgil · 19 years ago

no change on CTR for me. it even improved after a redesign.

Showbiz Intriga? Get It From Boy! · 19 years ago

my earnings dropped 85% sept. and october was record breaking for me though..but i think its not because of the clickable areas but because of the Manage Ads feature..it messed up everything in my adsense code, and channels are not working. i suddenly got a lot of PSA’s.

Its now back slowly but surely to normal though..thank God!

jhay · 19 years ago

Same thing happened to me right after my PR was slashed. Traffic went down considerably and so did the CTR. It became worse when the click-able areas shrunk.

I really wonder why Google has been acting up lately. Maybe they’re up to something big yet again. (Like world domination? :P)

Mindanao Bob · 19 years ago

I’ve seen small dips in CTR starting back in June, and every month since then. It’s not a huge dip, though, and doesn’t concern me too much.

AnnaE · 19 years ago

Dunno about Bidvertiser. Their ads don’t appear that related to the content of the page. Chitika is okay, though.

Half the daily income? With the slumping dollar, is the income drop approaching 70%? Haynaq….

Hezron Mariano · 19 years ago

Agree with yuga, i’m also experiencing huge drop in my adsense CRT. This might be the effect of Adsense reducing the clickable area in the ads. Hope Adsense will do some moves or else…Hello bidvertiser…Hello Chitika.

Rickey · 19 years ago

Nope. CTR is relatively in the same level, no dramatic drops or increases.

James | PinoyMoneyTalk.com · 19 years ago

I saw this happen in one of my experimental sites (a short story-collection site). CTR dropped by 50% leading to a 40% drop in Adsense income from last month.

As for my main blog at http://www.pinoymoneytalk.com, CTR and Adsense income dropped by 10% in early November after my site’s PR was reduced from 4 to 2 (then back to 3). Since then, however, CTR and income have stabilized.

I think the income reduction was caused by a lot of factors. First, the PR penalty caused some of my pages to be moved to later pages in Google’s SERPs thereby causing less visitors to the site. Second is the shrinking of the Adsense ad unit which you mentioned. And the third, I also agree that the 4th quarter is a slow quarter for advertising. I’ve seen that happen in my site for the past 2 years now.
