Site Targetting vs Contextual Targetting

Now we know the truth, how do they compare?

[vincevincevince]

The new adsense reports, when you select to view by Ad Unit, allow you to show the Targetting type.

Waits while everyone runs to check...

What I want to know is how well the ad unit eCPM compares, like for like, between your Site and Contextual targetted income.

For me I'm seeing that Site targetting is giving less than 10% eCPM compared to Contextual targetting in all cases.

Aircut, you should make sure your reasoning is correct before blocking advertisers willy-nilly. I'm pretty sure AdSense has other ways of targeting ads to your site (given that many sites are not targeted and CPM ads are a recent introduction anyways). Plus I'm not sure whether site-targeted ads even show up in the preview tool.

i am not blocking willy-nilly as you said.

i blocked a bunch of MFA sites, and couple of others that were site targeted.

48 hours has passed and the 30% drop in ecpm i was reporting in other thread which i experienced the entire month of february, resolved to normal healthy earnings.

i know and understand that google makes money from those sick MFA sites, but i am for one wont send my users to these dead-ends, and i am sure that repeated visitors will avoid clicking on google ads if they learn that all they find behind it is a junk mfa site.

sorry for the rant. back to the point. i am considering every site for its value for my users and its value for my earnings before putting it on the limited 200

I'm just saying the the technique you gave for identifying site-targeted ads -- that test you described involving the preview tool -- doesn't appear to work.

When I tried it, the preview tool brought up lots of ads that do not appear to be site-targeted. In fact I'm fairly sure they aren't, because I did the test on a lesser-known site that according to Google's reports has never had ANY site-targeted impressions or clicks. The ads appear to be simply targeted to the general theme of that site.

[....48 hours has passed and the 30% drop in ecpm i was reporting in other thread ...]

I am expecting 50% drop for the first day income after having my targetting and advertise on this site resumed, impressions and CTR are just normal, it is the drop of EPC.

AS algorthm in most are conservative and always starting from the negative side, it looks like always go with a "reset" effect and then start to recover steadily, let see if it can work out or it will go to my toliet ... :P

I have over the past 12 months trimmed back my percentage of pages running adsense on my site. Partly because some were so low CTR wise that I felt it was the right thing to do. Partly because I had some now resolved ranking problems and I had to focus my limited traffic towards the paid advertisers on many content pages rather than letting the clicks go to adsense. When I saw how this was helping my bottom line I continued to do so.
The site that is receiving enough site targetting to be statistically reliable get .5 the eCPM as the contextual for that site. The site targetting ecpm is very near the contextual ecpm for my entire account however.

i don't know if it is because or despite my filtering. :-D but my ecpm has climbed back to normal and click through has become more realistic.... my earning are back to the 200-250$ a day from the low 160$ before the filtering.
