Hi Lori
There are generally two types of ads provided: banner ads and interstitial ads. Banner ads are small, generally around 50 pixels high that can usually be placed at the top or the bottom of the screen. In many games, banner ads are ineffective. Imagine a fast paced game where the player is constantly doing something. They will never interact with the ad and if they do, it breaks the flow of the game. But people use them anyway. Interstitial ads are full screen ads that are designed to run “in between” other screens, for instance after your menu screen but before the game actually starts. These full screen ads earn more money but you have fewer of them.
Next, there are multiple ad providers that you can use. They all have their pros and cons. Some people will use multiple providers to make sure they are always getting ads. Many ad providers don’t have the inventory (sold ads) to always have ads for you. It can take time for your ad to earn enough reputation to get their available inventory. Because of that several developers will support multiple ad providers to try and make sure they get the ads needed to always show them.
All Corona ads are done through plugins and most are available to Starter accounts. Occasionally there will be an update that requires a daily build to implement, but usually the next public release catches up. This will involve adding some code to your build.settings for each plugin you need.
Each ad vendor will require you to setup information with them including how to pay out to you, etc. They all will be different. You will create an entry for your app and in many cases you may have two or more per app (one iOS, on Android for instance). You will need the ID number they give you (and they all call them something else).
In your Corona SDK code you will require the plugin in, then call
ad.init()
with some parameters and some listener function and the ID you got for the ad provider. after that you can call ad.show() to show the ad (it needs parameters too).
As far as In App Purchases, you will need to be a Basic, Pro or Enterprise subscriber to use IAP. Google’s IAP v3 is implemented as a plugin but Apple’s IAP is built into the core with the store.* API.
