Have interest-based ads gone live yet?

[londrum]

just wondering if anyone has done any testing to see whether interest-based ads are live on their site yet?
i know google gave a date for it going live a while ago, but apparently it only affected the select few, and i don't think the lowly guys (like me) got drafted in.

but i've just had probably the worst week and a half that i've had for ages (dropped by nearly half), and i can't find a reasonable explanation.
i know the economy's bad, but i've had a dip over several months which i am blaming on that. but this new dip is a sudden thing that happened overnight and hasn't bounced back.

it's pretty tough to tell whether interest-based ads are live on your site, because you don't know whether they are just untargeted ads.

Same thing here, I wonder if interest-based ads are the culprit. May has been terrible. If it's the economy, why now suddenly, why this month when the economy looks a lot better than it did in the months before? I have been affected since September but never to the degree that I am this month, a few weeks after their announcement.

I disabled interest based ads on my account, I will see if this helps anything out

instead of having interest-based ads competing on equal terms with targeted ads, they should do it so they only display when there is no targeted ad available. that way everyone is happy.
google gets to show more ads, and we get the possibility of extra clicks where there might not have been any.

if you've got a page, or a channel, that's been selling some high price tickets for years, and they end up clicking on an interest-based ad for fluffy socks on that same page, surely that is going to drag down your eCPM.

It's very hard to tell. I had just a discussion with a friend in Thüringen Germany about 600km distant.

We looked on the same page, but 80% of the ads had been different.

Same themes, but different companies.

I have since 1997 a statistic of different search queries leading to my sites. (referer log file evaluation)

The statistic shows more than 1 million differen search queries.

I would be curious how many different ads are appearing on my sites.
Maybe even more than different search queries?
