Welcome to WebmasterWorld Guest from 184.108.40.206
This morning I have been comparing the past few weeks metrics since yesterday, Thursday 17th December, heralded a new CTR low, therefore comparing recent metrics, and especially so since the introduction or personalised search, I have the following to report.
These figures are compared to 1st November 2009 to 4th December 2009
5th December to 14th December - Page Impressions normal average
15th December to 17th December - Page Impressions normal average
Obviously my eCPMs and earnings have reduced considerably, yesterday my eCPM was -24.5% but significantly earnings were -38% of 1/11 to 4/12 average.
How much of this is to do with personalised search as discussed in the search forum?
Personally it seems to be very coincidental how I have seen a gradual slide to this new low since 5th December and especially so when comparing AdSense metrics to previous Decembers.
Are personalised search results now serving non-relevant or garbage widget ads on my pages that I cannot see?
Has anyone else seen such a reduction in CTRs since 5th December?
I'll repeat, I did expect my earnings to go down in December however not the anhiallation of all metrics.
As for the CTR drop, are we talking about adsense CTR or something else? Because I don't think that Personalized SR will affect which ads are displayed on your site. It should only affect the SERPs and therefore the number of visitors you get. Unless that is I missed something here?
Like Husky Pup, I see pretty close to the same advertisers in search that I see on my sites. And I assume it's because those advertisers are getting conversions from both. That doesn't necessarily happen in every niche.
And, for what it's worth, you can't possibly know if the more lucrative ads are in search, because you don't know what those advertisers are paying at the given moment you see that ad.
Google actually wants to get more of them advertising on content--if you lurk on AdWords you'll see discussions from time to time about this, along the lines of "so I got a message from Google encouraging me to look at the content network. What are your experiences with it?" And that draws a wide range of responses!
