google display network question

Hey guys, I have weird issue on display network. I was getting cca. 1000 clicks a day for one ad, those were coming from 1 anonymous placement. However today I don't see traffic anymore from that placement, what could it be? Bidding too low, site owner blacklisted my ads?

Placement may also have been dropped from the network for various reasons, e.g. they could be monetising with another platform.

Or their anti performance marketing algo at work

Things are getting weird like I have 600$ daily budget and I'm bidding 0.15 CPC, I was maxing that budget last week, and this week I can't get over 300$, CTR might have dropped from 0.5% to 0.41% but that's it, is that normal and what would be the best solutions for this? I'm targeting very broad

A CTR drop of 20% also means an eCPM drop of 20% in the eyes of the ad server. This could be enough reason to see your campaign degraded to a lower ad slot (and other advertisers taking over your position), resulting in less volume.

Fail to understand, how a CTR drop would imply eCPM drop? Do you mean to say eCPC drop instead?

I can as well maintain the same eCPM but still the CTR can be low due to may be banner blindness or low ad positioning etc., Hence a drop in CTR doesn't imply that there is drop in eCPM.

Somehow I have this problem too. Maybe the site owner blacklisted your ads? Or maybe Google retrospectively rejected your ads. I have 100% of my running ads rejected by them.

Had a 3 hour sleep last night, so correct me if I'm being blurry here.

Assuming the OP his av. CPC remained the same during the CTR drop he experienced, this could have caused a lower eCPM - again in the eyes of the ad server - so perhaps RPM would be a more appropriate metric here.

To clarify: every 1k impressions on his former 0.5% CTR would have gathered 5 clicks x 0.15 CPC = 0.75 eCPM. Do the math on a CTR of 0.4% and you'll get an eCPM of $0.60. Since it's the ad servers only mission to achieve the highest eCPM/RPM for the publisher and its employer (in this case G.), this might have been the reason for the volume to go down.

Notice the huge IF in this asumption: IF the av. CPC remained on the same level...

If CTR would be the problem then why after creating new campaign with new ads (0.5% CTR) gives same problem, 600$ budget spending like 100$

Well, the eCPM issue only comes in to play if bidding in a CPC mode - as when bidding CPM the revenue to the ad server/publisher is not dependent on CTR.

But imdutch is correct, a lowered CTR will influence eCPM and thus delivery algorithms.

If your CTR was the same and delivery volume went down there are several possibilities:

1. You are being out bid
2. The publisher is providing less traffic.

If your CTR decreases then it will lower eCPM which will change your standing relative to other advertisers.

I'm not entirely sure what's happening in your case, but my regular suggestion is to just bid higher. It's a simple test to do and will likely answer your question. Really, you should do such a simple test as part of sensible problem solving habits.

I tried bidding higher but that didn't bring much more traffic, anyway gonna test more and if I found a solution I post here. Today I tried with new domain campaign, if that doesn't work I Will also try with new adwords account (in case some websites banned my pub ID for ads).

Great, sounds like sensible further tests to do. Let us know if you get a breakthrough!
