Admob: eCPM - $0.11, CTR = shitty always, due to bad text adverts
Millennial: eCPM - 0.12 CTR = 0.64%
Leadbolt: eCPM - $0.02 CTR = 1.1%
Jumptap: eCPM - $0.10 CTR = 0.5%
InnerActive: eCPM - $0.08 CTR = 0.3%
mind:
Yes, I am seeing the same drop in eCPM with Admob - from a high of $0.45 during Christmas/New Years holiday season to a steadily declining (nearly linearly) down to $0.2.
This prompted me to give banner inventory to Millennial Media (mmedia.com) - which I had earlier scaled back because it was earlier giving same eCPM as Admob so I chose to consolidate revenues in Admob.
However mmedia.com ALSO seems to have low i.e. $0.06 eCPM (!?) - or maybe it is just starting up since I had been giving it very few banner ad impressions last many weeks.
So it seems all ad networks giving low eCPM.
HOWEVER, there was another change I did that MAY have changed things - I had noted that my Admob mediation “auto-refresh” settings were set to auto and not 60 seconds etc. I had then set that to 60 seconds.
I had attributed that to maybe mistakenly having set that to auto during testing some time back (?) - however eCPMs were fine during Christmas/New Years - so that couldn’t be it (?).
But after setting it back to 60 seconds - I saw that Admob eCPMs jumped slightly.
Maybe you can check your Admob refresh rate (for each app) - maybe there is a possibility that some bug at Admob caused all users to have their settings set to auto for some reason (?). If not (i.e. your auto-refresh is set to 60 seconds etc.) then just ignore this suggestion.
mind:
Regarding other revenue for Word Hero - have you considered Leadbolt AppWall as interstitial full screen ad - or Leadbolt’s new dialog ads - that may suit as it shows the background and overlays a dialog box with Yes/No (I think - I haven’t tried it).
Another option is StartApp - per download revenue.
There may however be an issue with whether you need to cut out other revenue if users click - or offer a totally ad-free version.
AppBrain at end-of-app is the other option (either once every 3 days as they suggest or every time app exits).
In-app billing if you have access to Google Checkout in your country.
GetJar gold coin payments - or Sponsorpay.
I am in the process of evaluating GetJar - however the advantage of these methods are that they are “orthogonal” to the other revenue streams i.e. whoever pays this way will not be cutting into your other revenue - so it doesn’t hurt to include that.
And I am going to be implementing Leadbolt AppWall (as David and Magnesus say it outperforms AppBrain) - also my current interstitial Greystripe is very low paying.
In any case - the BENEFIT of these appwalls - is that you most-of-the-time get paid for installs - and this revenue will not be seasonal - i.e. while banner ads etc. ARE dependent on ad SUPPLY - with appwalls you generally get paid per install (for example for AppBrain it is $0.18 per install or so) and it all depends on USER-INTEREST in new apps.
If your app is a new app - with high churn (i.e. lots of new users try it) - then appwalls may also be suited - as new users tend to click all over the place - recurring users tend to tune out the ads.
