Still I had this problem. If it’s resolved, my adsense revenue will increase alot. Recently we hits 600K pageviews, Discourse is just awesome but still the ads income is poor. 
Are these Pageviews Per day?
All time pageviews. Around 4 months page views.
If you don’t mind the asking, I don’t mind the answering 
For clarity, the pageviews of 600K are they analytics or adsense pagevciew metric?
What kind daily average for one or more: revenue, clicks, impressions or pageviews within adsense?
Yes but like most of Google UI/UX it’s incredibly unintuitive. I really don’t like their interfaces setup at all… but that’s another topic!
Auto ads > (click) NEW URL GROUP
Here you can specify specific URL’s and how the auto-ads appear or not! 
Ok cool, general stats are fine. Like week or month vs revenue.
Well anyhow. I had a look there at our stats for comparison.
April 12 (Pageview Stats)
22,325 - Discourse:
3,970 - G Analytics:
1,910 - Adsense
Never having forum pageviews from previous forum as we do with Discourse, not sure what to make of the massive difference between Discourse Vs Google/Adsense stats. Thus I can not draw no conclusions and only consider is:
A) Uh OH! Something is seriously not working!
B) This is normal, there is a technical explanation.
This is probably getting a bit off topic so to take it back. In my experience, auto-ads once you get them under control don’t always give a great return but it can help with keeping the total a little higher.
You have to observe how they appear. So far they are not so bad in Discourse. The mobile one are often the most invasion with full screen display, these can really annoy users. I generally turn these off.
Thanks for the insight. Can you clarify what is the duration covered for those stats, a week, a month, more/less?
All time i.e, 6 months.
Ok so your page RPM and Impression Rpm are very low. That doesn’t help but impression from our experience is key.
What I’ve found is our page RPM and impressions RPM has gone up since move to Discourse but the impressions have collapsed. Click are down a bit but not as much as impressions.
Red = Page Views
Yellow = Impressions
Pg RPM = Purple
Imp RPM = Blue
.
You can see the point where red/yellow hit the floor, and it hasn’t improved over time. It’s a big problem.
Perhaps we’ll try the other plugin but the only other option that we can see is to migrate to another platform.
You can see here, the Revenue pattern, Before / After Discourse, it’s not hard to tell.
Discourse is a great platform but if like many forums you rely on revenue to pay for maybe the cost to keep a labour of love alive, or actually make a living income from your online forum or website, then you should think very hard before you migrate to Discourse (or any platform for that matter!) until you have tested or are sure you are not going to see a 50-80% drop in your income.
We didn’t really come across this subject until too late, thus post this as a cautionary tale.
We don’t know what it is exactly that causes the problem yet, it’s been suggest it something to do with how discourse server up the pages, but nothing more specific than that!
Time has not solved it, even as user engagement and new signup is all trending in the right direction. Even if you loose 10-15% of your traffic it shouldn’t equate to 50-80% drop in revenue, should it? How then if so?
Yes there are also google whims but in this instance you can clear see the switch over point.
It’s night and day.
Just to focus on the impression point more, since we have the data from before and after, in simple number terms.
3 months Before switch = 2.2M (approx)
3 months Switched = 0.5M (approx)
The strange thing is Discourse gave us better mobile ad serving often where we had zero, and yet the impressions fell off the cliff! 
The question has to be asked:
*What causes Discourse to score such low impressions?
*adsense
How is AdSense measuring pageviews and impressions? Remember that Discourse is a single page app, so how does AdSense count a pageview? How do your ad placements and frequency of ads per page compare with what you’re showing in Discourse?
i think the problem is the Hot Reload, when a page is loaded you also load all the ads, but during surfing these ads are never reloaded, so you have 100 pageviews in Discourse but only 1 impression in Adsense.
Dato che dovremmo inserire il codice Auto Ads su ogni pagina in cui vogliamo che vengano visualizzati, come posso inserire il codice Auto Ads in tutte le pagine di Discourse?
Altrettanto importante è il fatto che il codice Auto Ads sia lungo come 7859204789981798 (non reale) (ed è esattamente lo stesso del mio codice Editore di AdSense), ma ho letto che Discourse si aspetta codici ADS di 10 cifre. Quindi, affinché Auto Ads funzioni, come e dove devo utilizzare questo codice a 16 cifre fornito da AdSense Auto Ads?
Esiste un modo per inserire il codice degli annunci Amp Adsense in Discourse?
A volte gli annunci non vengono visualizzati quando clicco sul prossimo argomento; devo aggiornare il sito per vederli di nuovo, poiché Discourse è una SPA.
Quali sono i vostri suggerimenti?
@Viki Non capisco perché vorresti mostrare annunci AMP in Discourse. Puoi spiegare?
Perché a volte gli annunci normali non vengono visualizzati quando si clicca su ‘prossimo argomento’ senza aggiornare il browser, quindi mi chiedo: gli annunci APM sono adatti per le SPA?
Google ha rilasciato un aggiornamento per Auto Ads a ottobre, ma sembra che non offrano ancora demo o screenshot chiari su cosa aspettarsi. Inoltre, secondo le note di rilascio, il codice può ora essere fornito tramite qualsiasi unità AdSense standard, quindi l’integrazione con Discourse è ora senza interruzioni?
Qualcuno lo sta già utilizzando in produzione? Sarei molto interessato a vederlo in azione.
