Under delivery of contract Campaigns

[Dharmesh Maniar]

Hi,

I have created 2 contract campaigns on one ad zone with daily limit of impressions per day.

So the 1st contract campaign is created to deliver 300,000 impressions per day with priority as 10. 2nd contract campaign is created with 100,000 impressions per day with priority as 10.

I have also created 2 remanent campaigns for the same zone.

We receive total 850,000 impressions per day for the zone.

Now the contract campaigns are underdelivering by 50%.

1st contract campaign gets only 150,000 impressions per day and 2nd contract campaign gets around 50,000 impressions per day.

When I check probability of the zone it shows 1st contract campaign  around 16% and 2nd contract campaign around 5.47 %.

Which according to 850,000 impressions per day comes to the delivered impressions of around 150,000 (16%) for 1st campaign and 50,000 (5%) for 2nd campaign.

The scheduled maintenance also running every 1 hour properly. Checked the debug.log and there are no errors in it. 

Am I missing something.

Hi @Dharmesh Maniar,

Thanks - this is a terrific question, with some excellent detail, which makes understanding your problem easy!

You've inspired me to write a new troubleshooting guide - please take a look at https://documentation.revive-adserver.com/display/DOCS/Contract+Campaigns+Under-Delivering and see if this is of any help?

Thanks!

Hi Andrew,

Thanks for providing detailed troubleshooting guide.

I went through the guide and checked it thoroughly. We do not have any delivery options or any delivery capping for these contract campaigns.

I doubled checked the total impressions we get in a day are around 850,000 and out of that around 650,000 impressions are going to remanent campaigns.

One point I want to add is that traffic on the site is mainly between morning 9 to evening 6. After 6 in the evening traffic drops drastically.

So around 500,000 impressions on the site comes between morning 9 to evening 6.

Is there any impact on delivery because of such traffic?

 

Thanks!

Hi,

Can anyone help on this?

Hi,

Okay, good news that there's no delivery capping or delivery targets for the contract campaigns - that rules out one possibility.

The fact that the traffic comes in during a time window of 9am to 6pm should not matter too much - Revive Adserver has a relatively simplistic way of predicting the volume of traffic expected each hour, which is needed to calculate the probabilities, but that should not be causing an issue with this type of traffic pattern.

I think if we want to go any further with debugging this, we'd need to get information about what the "maintenance priority engine" is actually thinking is going on, and what it's deciding to do.

In your config file, under the [log] section, can you please change the priority value to 7? (It would normally be 6.)

Then empty our your debug.log file, and wait for hourly maintenance to run. Then we should have a complete view of what the MPE is doing...

Thanks.

Sorry to interrupt, I have similar case, underdelivery in the first day of campaign. My understanding is that based on inventory, probability % was calculated but then banners were excluded because of targetings (capping & site-variables) which is fine.

But, my questions is, will Adserver increase probability in the next days, as learned from first day that initially calculated probability % was too low?
