Google AdMob

Google AdMob is well suitable for small businesses however you must take into consideration that their payout is lower than other providers. It is a good app to generate revenue and it does pay out pretty quick however the payouts can sometimes vary.

Pros:
1. Best cost per click.
2. Best eCPM.
3. Ease of integration.

Cons:
1. Poor support.

Google AdMob is the best choice in my opinion for any developer or company looking for a reliable way to monetize their app traffic and generate revenue from relevant ads displayed inside their mobile app, and it can be easily integrated into any IOS or Android App.

If you already have an apps in the android and iOS environment. And then you want to add advertisement for gaining money through various advertisement type. (Banner, full page ad. And reword ad. Etc.) I think Goole AdMob is a great tool for setting that easily and makes money easily. It works well and is easy to use. One more thing if you're familiar with javascript, it's a really good chance for you.

Google AdMob is a powerful mobile app ad platform that provides tools to monetize and leverage mobile devices. One of its great benefits is being able to integrate it with Google Play Services.

It is extremely well suited for those that develop apps and are interested in promoting them and monetizing them too, particular in companies that are already confident with their apps functionality. Because the scenario where Google AdMob is less appropriate is when your app is still in an early stage, and you'll definitely get it noticed by using Google AdMob, but if the users download your app and it still has glitches, you lost user confidence and it will be very hard to regain it.

AdMob is suited well for mobile app advertising on Android for Google Play and Apple. AdMob is not very well suited for alternative Android markets. AdMob interstitials and reward video ads are much more efficient than banners.

As for technology and implementation... I think they are superb. But in today's world you can't go around doing whatever you want to stroke your own ego. You have to care for your clients & communicate with them. AdMob loses all respect there. I understand banning those illegal click farm guys in Asia/Africa, but banning a developer in Europe who has nothing to do with click farms, and then refraining to verify their own data collection is absolutely nauseating.

It is very quick to integrate with the application. You will start earning within a few days. It has a well-written API. You can go for it if you want a quick implementation but if you want to highly customize your ads then Admob is not a good [fit]. It has also less CPC in comparison to its competitors.
