What is Supply-side Platform?

A Supply-side Platform (SSP) is an essential part of the programmatic advertising ecosystem that allows digital publishers to manage, sell, and maximize the performance of their advertising spaces or inventory. It’s programmatically connected to Demand-side Platforms (DSPs), ad exchanges, and ad networks, facilitating real-time bidding (RTB) for online ads.

The SSP assesses available ad inventories, categorizes them based on several parameters like visitor demographics, behavior, and context, among others. Then, it exposes those inventories to potential buyers (advertisers) who bid against each other in real-time. Once a winning bid is identified, the SSP ensures the ad is displayed on the publisher’s website or app.

Formula

The SSP doesn’t specifically operate on a formula, but its process can be simplified into three steps:

  • Analyzing and categorizing available ad inventory.
  • Presenting the inventory to potential ad buyers and initiating the RTB process.
  • Ensuring the successful display of the winning ad.

Example

Large-scale digital publishers like news websites, blogs, or social media platforms incorporate SSPs to sell their ad spaces. With the SSP, the publisher sets the minimum price for their inventory. Once the SSP analyzes and categorizes the available ad spaces, it opens them up for bids. Advertisers (through DSPs) that match the set parameters place bids, and the highest bidder’s ad is displayed to the end-user.

Why is SSP important?

  • Automation: SSPs eliminate the need for manual ad placements, making the process economical and efficient.
  • Optimized revenue: Through real-time bidding, SSPs ensure that each ad space garners the highest possible revenue.
  • Greater control: Publishers can set minimum price floors and control the type of ads that appear on their website.
  • Global reach: SSPs allow publishers to expose their ad space to advertisers worldwide, increasing inventory demand.

Which factors impact SSP?

  • Transparency: Clear communication around fees and charges can improve buyer trust in SSPs.
  • Improved Ad Quality: Ensuring the display of high-quality, relevant ads can enhance user experience and generate better revenues.
  • Advanced Audience Analytics: Incorporating advanced machine learning algorithms can help generate better insights about visitors, boosting ad performance.

How can SSP be improved?

  • Traffic Quality: High-quality, organic, and repeat traffic can attract better bids.
  • Website/Content Quality: Better website engagement can improve ad performance.
  • Technology: The SSP’s technology, especially its ability to categorize inventory accurately and attract better bids, significantly impacts performance.

What is SSP’s relationship with other metrics?

SSPs directly relate to the advertising revenue metric. The higher the bids an SSP can attract, the greater the ad revenues. Indirectly, through the display of well-targeted, high-quality ads, SSPs can positively impact user engagement and retention metrics. Therefore, SSPs play a crucial role in both ecommerce marketing strategies and revenue generation.
