I am pretty new when it comes to Android App development and started developing apps recently in January this year. Since my apps are all free, the only way left for me to monetize my apps was to integrate an Ad Network. After doing my own bit of research, I started off with Admob, the most popular and trusted Ad Network. The reason I chose Admob over any other network like AirPush, Mobiclix, Buzzcity was solely considering my App target region. My apps so far are only targeted for Asia Region and based on the reviews; Admob provides the highest fill rate worldwide. After 4 months since the launch of my first app, I can definitely vouch for that. Admob has been providing 99.99% Fill Rate consistently.
The eCPM is however a different story altogether. My average eCPM with Admob so far has been $0.35, which is way too low. I understand that this is also related to my apps being for the Asia region. I am sure that the eCPMs for other regions especially Americas and Europe are much higher. One month into the launch of my apps, I started looking at various other ad networks to experiment and increase the eCPM. I zeroed on LeadBolt and decided to give them a try.
Leadbolt offers various types of Ad Formats like AppWall, Icon, Notification and of course the Banner, which meant that I could integrate LeadBolt in my apps without doing away with Admob. I must say that I made the right decision and the results so far have been pretty impressive when it comes to eCPM. An eCPM of $1.20, which is almost 4 times that of Admob! The best part about LeadBolt is that you do not even need to integrate the SDK for their AppWall and Banner ad format. Personally for me, Banner Ads of Leadbolt did not perform as well, so I let Admob take care of the Banner Ad slot in my apps. The format which has worked best for me is the AppWall and Icon.
I strongly suggest that you integrate LeadBolt in your apps. Trust me; it is one of the best paying Ad Network out there.
Another interesting Ad Network which you can try is StartApp. These guys pay you for every install. I would definitely recommend you checking out StartApp as well.
