I blocked them all, so I am no help to you.

I blocked them all also.

I'm very curious about what the "Google Testing Network" is? I have not seen an explaination of that one anywhere, maybe I just missed it.

Beyond that, they (ASA?) said this was going to be rolled out slowly, so who knows if it's even affecting a given site yet?

Anyone know a way to tell for sure?

I haven't done as poorly in years as I have since this new network thing came up. Yesterday I blocked the external Ad Networks and my results were even worse. The worst earnings in several years!

My site has continued to grow and grow, but my Adsense earnings have been less and less. VERY frustrating that I am giving Google more impression now than when I was earning much more money.

My stats are doing ok at the moment - nothing spectacular, and not necessarily outside usual fluctuations, but - well, it's fluctuating up for a change. What that's down to is anyone's guess . . .

I haven't blocked any of the networks - don't block anything at all, for that matter.

Why do some of you block the ad networks?

How can you tell if your ads are coming from one of these new networks? I haven't been able to see a way.

Good question. Anybody know the answer?

The only way I know is to check when the destination URL doesn't match the display URL, type the destination URL into Google and if it is from an ad network usually there will be some posts about the URL somewhere.

Can someone please explain this?

"Allow advertisers to use their audience information to deliver more relevant ads to my site."

Does this mean more targeted ads or more interest based behavioral ads?

Why do some of you block the ad networks?

For me, two reasons...

1: If Google cannot be bothered to inform us what each of them target/cater for, then I cannot be bothered to accept them.

2: Sites that were previously banned by Google can now appear via the backdoor by using one of the other networks. No thanks.

could this explain lack of targeting in the recent week?

I had three consecutive days where my eCPM doubled and one day even tripled for one site. The ADS were great and relevant to my niche. Now I am back in the dungeon.

Maybe a new Ad network kicked in for those days, maybe Google was testing something. My CTR was a half a point higher too.

Adsense needs to be more user friendly.

It looks like the ad networks are frequently changing. A week ago I had nine listed, now it's just the Google Testing Network and one other. Anyone else notice a smaller list? I've seen steadily increasing earnings in recent months with roughly the same click counts, but of course there's no way to know what correlation might exist.

Same for me. I had all the networks blocked, there were 9 if I recall right, now just 2.

What is the Google Testing Network anyhow? Anyone know for sure?

I blocked interest based adverts for two days and earnings went up for a few days. But then earnings fell dramatically. When I reenabled interest based adverts only two networks appeared (Google Testing Network and another one) reappeared. I'm not sure if Google has "fixed" something again.

I've blocked them from the very start and not looked back.
Good earnings. Smashing my baseline everyday. Old code used. Veranda Large. Adverts at bottom rather than above the fold.
