Rate Limit Reached for Facebook Audience Network

[minas90]

Hi, We were getting rate limit reached messages from Facebook AN. We reported the bug to Facebook, after their investigation they concluded that it's caused by the implementation of AdMob mediation.

Here is the reported issue for more context: https://developers.facebook.com/support/bugs/1057131381115364/

Please let me know if it's something that you can fix on your side or Facebook has an issue at the moment.

Regards, Minas

Do you enable Ad network optimization within AdMob for Facebook Audience Network? If so, we have been seeing some rate limiting errors as part of this ad network optimization integration that sounds consistent with this context. We'll reach out to Facebook for guidance on how we can resolve this.

[minas90]

Hi @ericleich Yes I enabled ad network optimization. Please contact to Facebook to figure this out. As Facebook refuses to address this issue and claims that it's caused by AdMob.

Hi again, We disabled optimization, removed all the mediation related stuff from AdMob and added it back few days later. We started to get rate limit reached messages again.

Hi, I am also getting this Rate Limit issue and had the same experience with Facebook - they pointed me here. Revenues are being affected :(

If there is a temp fix I can implement I am all ears.

Thanks!

No progress made since last week since it was Thanksgiving holiday, but we expect to get in touch this week.

Workarounds for now:

1) If you also use Facebook's API directly for things other than AdMob ANO and it's breaking that workflow, I'd recommend turning OFF ANO in the short term to fix your other workflows. 2) Make sure the manual eCPMs set in your AdMob account are accurate for the Facebook Audience Network line item, as AdMob falls back to the manual eCPM value you set when ANO is not working.

Thanks Eric, Happy Holidays! I'm only using Facebook's API for ads so I think only #2 applies to me. Should I leave the AdMob setting on automatic or set it to manual myself?

Thanks again!

@danzada1 Apologies for not responding to this earlier. I think there wouldn't be any functional difference here if you kept the automatic setting on or not, other than if you kept it on, it could automatically resolve itself once we fix the reporting API issues.

In other news, we were able to get in contact with Facebook, implement some of their suggested changes, and are seeing error rates going down. It would be great if we could get a confirmation from you or @minas90 if you see the issues resolved on your side.

Thanks Eric, I have not gotten a Rate Limit error since November 25th. However I'm noticing pretty strange behavior regarding the mediation of my interstitial ads. The network requests for Facebook interstitials is only about 7% of the total, and I'm only using Admob and Facebook to serve ads. My banner ads are split 50/50 so I expect the same for the interstitials. Facebook interstitial mediation also shows that it has not been optimized in more than 7 days with a bit red !. Any idea what could be at issue?

Thanks!

Hi Eric, were you able to look into my last question? I am still seeing the same issue and actually it has been happening since before the rate limiting.

Thanks!

[danzada1]

Hi Eric, I'm still seeing this error. Is there something I need to change on my end? I have a feeling this is drastically affecting my revenues.

Thanks!

@danzada1 The rate limiting problem has been resolved, so I'm closing this particular issue on GitHub. If you're still having issues, it's a different problem, possibly related to the credentials you've entered. Can you follow up with this on the Google Mobile Ads SDK developer forum?
