Top 10 SSPs (Supply Side Platforms) with High eCPM and Ad Fill Rate

Why settle for minimal earnings from your app when there are alternatives to monetize more? To make this happen, you must act strategically and choose the best SSP (Supply Side Platform), the platform where you can make your ad inventory available to the global demand.

While there are numerous SSPs in the market, some with defined niches (such as gaming apps), we can't just choose at random or leave everything to chance. We should aim to use platforms that connect with multiple sources of demand and offer the best effective cost per mille (eCPM) for every thousand impressions.

Which SSPs are right for you? What things should you know before choosing one? These are some of the things we'll break down in this article. Additionally, we'll present a top ten list of the best Supply Side Platforms for you to choose the one that suits your needs.

Key Characteristics of a Successful SSP / Supply Side Platform: What to Consider

An SSP, also known as a Supply Side Platform, is a tool that helps publishers manage, coordinate, and make their inventory available to advertisers.

In essence, an SSP serves as the main interface to connect with Ad Exchanges and, consequently, negotiate ad spaces with advertisers who manage their purchases using Demand-Side Platforms (DSPs).

In this context, every publisher's concern should be to find an SSP that possesses the following characteristics:

# 1 Integration with Multiple Platforms: Before choosing an SSP, you should research the types of integrations it offers and whether it can connect with various sources of demand to secure the best advertisers and achieve a high fill rate.

# 2  Real-Time Auctions: If the SSP you're considering doesn't offer real-time auctions, it's better to seek an alternative. Real-time auctions in SSPs create an environment where supply and demand prevail, leading buyers and sellers to compete for ad impressions, thereby increasing the chances of finding advertisers who maximize the value of each impression.

#3  Effective Inventory Management: Apart from real-time auctions, one of the most valuable features of an SSP lies in the autonomy it provides to the publisher. You should aim to join an SSP that allows you to manage, organize, and categorize your inventory seamlessly.

#4  Data Analysis: In the realm of programmatic advertising, performance analysis is crucial for making informed decisions. An efficient SSP should gather and analyze user information and ad performance data, including metrics like clicks, conversion rates, and other key performance indicators (KPIs).

#5  Audience Segmentation: Ideally, an SSP should understand audience behavior and preferences. This helps publishers segment their inventory to specific and potential advertisers, providing a win-win situation where publishers make money and advertisers gain greater visibility.

Additionally, you should choose an SSP with an intuitive interface that's easy for making adjustments, managing inventory, and simplifying other tasks related to programmatic advertising.

Advantages of Using an SSP / Supply Side Platform

It's challenging for an app to achieve higher monetization levels without the right SSP and proven tools for maximizing earnings.

But what are the benefits of having an SSP with the characteristics we've described above? Here are four advantages:

  • Attract the Right Advertisers: An ideal SSP allows you to optimize your ad inventory and attract users who are compatible with your content. This is crucial for achieving a better eCPM.
  • Improved Fill Rate: Connecting with advertisers whose products align with your audience ensures higher acceptance and a greater percentage of effectively displayed ads. Metrics will reflect the progress made.
  • Flexible Inventory Pricing: Having control over your impressions is an advantage that enables you to set a minimum price for your ad inventory and adjust it according to market behavior.
  • Avoid Repetitive Ads: Seeing the same ad repeatedly in an app can lead users to become disinterested and either skip or, in the worst case, stop using the application. With an SSP, this is mitigated as the system sets an ad frequency cap with DSPs.
