Does blocking of Certified Third Party Networks increase revenue?

I stumbled upon this topic on webmasterworld where Publishers are discussing and testing

if blocking of Certified Third Party Networks will increase your revenue.

Back in October/November or whenever it was when people were reporting an invasion of unrelated ads, I blocked everything from the Certified Ad Networks.

I haven’t noticed much of a change since then in my revenue – except a slight increase.

I don’t know why, but it was for me. I can only assume having all that competition allows for sneakier tactics by advertiser to get low-cost ads. It was an immediate double to triple revenue change when I blocked them. Maybe not for everyone, but for me, it worked like magic.

All I can say, is try it for 3 or 4 days and see what happens. I think, now that I’m adding some back in- it’s like stock trading- I’m researching each company and deciding if I should give them an opportunity.

It has decreased my eCPM to 50%, since I have blocked certified ad networks.

At least it hasn’t worked for me in entertainment section.

I will unblock it all again.

There are many reports that differ in outcome which is nothing special for AdSense at all.

Like it is always with AdSense “what works on one site does not need to work on another”.

That is why I started a test of my own to see if blocking all Certified Third Party Networks will have an effect on my earnings.

So far I have blocked them for 2 days but I am not seeing any significant effects in neither direction.

I’ll wait a couple of days more and let you know.

What do you think about Certified Third Party Networks?

I don't know. It doesn't make much sense to block them due to how the adsense system works. The networks drive up the click prices at the auction block.

I blocked them only for a couple of days and earnings dropped dramatically. I lost a good chunk of money in those two days so I aborted the test.

Blocking google.com and groupon.com in the competitive ad filter might be a good idea. Those two are out of control.

Anyway, I am interested in knowing the outcome of your test when ready.

It never crossed my mind that blocking all would be a good idea but out of curiosity I just blocked them all and will see if I observe any significant difference over the next couple of days.

Will report back.

So far I am receiving a lot less 1 cent clicks while ctr remains stable and earnings seem stable too.

Too early to draw any conclusion but at least I don´t see anything negative, for now...

admin says:

So far after three days I see no difference either one way or another.

Earnings are stable. And because I wanted to see if there is a dramatic increase in earnings like some users reported on WW which did not happen to me I will reactivate the third party networks again.
