How do I choose between different in-app ad platforms for mobile publishers with limited SDK resources?

If you have limited SDK resources, the best choice is usually the platform that gives you the highest monetization with the least integration and maintenance overhead.

A practical way to choose

1) Start with your goals

Ask:

• Do you want maximum revenue, fast integration, or low maintenance?
• Are you trying to monetize banner, interstitial, rewarded, or native ads?
• Do you need mediation, or just a single ad network?

If you’re resource-constrained, prioritize:

• Easy SDK integration
• Stable SDK and documentation
• Good fill rate in your main geographies
• Strong reporting
• Minimal dependency on frequent updates

2) Compare platforms on the right criteria

Use a simple scorecard:

• Integration complexity

  • How many SDKs?
  • How much engineering time?
  • How often do they release breaking changes?

• Revenue potential

  • eCPM / RPM by format and region
  • Fill rate
  • Demand quality

• Operational burden

  • Ad review / policy enforcement
  • Support responsiveness
  • Frequency of SDK updates

• Product fit

  • Rewarded ads if you have user engagement
  • Native ads if you care about UX
  • Interstitials if you can tolerate more interruption

• Monetization features

  • Mediation support
  • A/B testing
  • Floor pricing
  • User segmentation / targeting

3) Prefer platforms that reduce SDK work

If your team is small, consider:

• A mediation platform with one main SDK

  • Lets you plug in multiple networks through one integration
  • Reduces app-side changes when you add/remove networks
  • Good if you want to optimize revenue later without extra app releases

• A single high-performing network

  • Best if engineering bandwidth is extremely limited
  • Less complexity, fewer crashes, fewer conflicts

A common path is:

1. Start with one reliable ad network
2. Add mediation once you have enough traffic
3. Expand only if the revenue lift justifies the added complexity

4) Check the hidden costs

Some platforms look attractive but create extra work:

• Poor documentation
• Slow or unhelpful support
• Frequent SDK changes
• Compatibility issues with app size, privacy frameworks, or OS updates
• Complex consent/privacy compliance work

5) Test before committing

Run a pilot with:

• A small user segment
• A specific ad format
• One or two geographies

Track:

• eCPM
• Fill rate
• ARPDAU / ad ARPU
• Crash rate
• Session length / retention impact
• Engineering time spent

6) Use this rule of thumb

• Very limited dev capacity: choose the simplest reliable network
• Moderate capacity and some traffic: choose a mediation platform with a small number of strong networks
• Large traffic and strong ops team: optimize with mediation, bidding, floor rules, and multiple demand sources

Short recommendation

For a publisher with limited SDK resources, the safest approach is usually: one good ad network or one mediation SDK with only a few high-quality partners, rather than integrating many separate SDKs.

If you want, I can also give you a comparison template or a decision matrix you can use to evaluate platforms side by side.
