    Why SDK Integration is Ideal for In-App Advertising

    Whether you’re deciding to integrate a new ad network, ad mediation or ad exchange, it’s important to understand what integration options you have. SDK integration invariably ranks #1 for mobile publishers. On average, an app has 15 integrated SDKs: analytics SDKs, attribution and engagement SDKs and advertising SDKs.
