“We highly recommend Promoted to top marketplaces and e-commerce apps. Promoted extends and compounds existing engineering investments in search and discovery to directly increase profitability at a reasonable cost. The Promoted team is a very good partner with us.  They are a delight to work with, are very responsive and transparent, and carefully explains all technical issues, giving our internal team full control of the Promoted integration.”

“Outschool chose Promoted because they weighed the costs and risks of building an order-of-magnitude greater infrastructure investment with working with the highly experienced and recommended Promoted team to get a working, managed solution that they would benefit from now.”

— Erwin Alberto

Outschool’s mission is to inspire kids to love learning. They believe the best way to do that is by linking learning to interests and giving kids the autonomy to pick their own path. To do that, Outschool wanted to better match learners with educators to increase search conversion rates, total GMV, and profitability. Existing recent investments in search quality were promising, and Outschool wanted to extend these investments to further increase conversion rates.

These investments had already brought Outschool search conversion optimization to the state-of-the-art in terms of systems and practices. Any further improvement would need to be an order-of-magnitude investment in a combination of user metrics collection, data processing, modeling, and real-time serving.

Outschool primarily compared Promoted to building search and discovery improvements in-house. Outschool chose Promoted because they weighed the cost and risk of the aforementioned infrastructure investment against working with the highly experienced and recommended Promoted team to get a working, managed solution that they would benefit from immediately.

Structurally, Outschool is a complex p2p marketplace with non-fungible, unique, and variable inventory. Its web app combines Segment for measuring user engagement with in-house search retrieval solutions.

Promoted maximized conversions (+11%) in search by applying the state-of-the-art in conversion optimization ads engineering to the problem of marketplace search results. We created a unified organic and promotion system for Outschool in three steps:

1Collect and join metrics

Outschool installed the Promoted client and server SDKs to collect more, higher quality metrics like insertions, impressions, and clicks. Then, they merged existing third-party event systems like Segment to add conversions. Promoted’s Metrics system automatically joined and aggregated these event streams in real-time for use in optimization and reporting.
2Re-rank search results

Outschool sent its search results to Promoted's Delivery system for optimized re-ranking and blending. Promoted and Outschool ran A/B user studies to measure progress and total impact.
3Continuous optimization

Metrics and Delivery create a feedback loop to continue to optimize and improve results over time. Through this framework, Promoted can support new allocation rules, product logic, and data. Outschool has the flexibility to add new listing types, cross-promotions, and internal promotions to its feed and search at any time, and Promoted's optimization will continue to work automatically.

Our Client Metrics Libraries integrated with Outschool's web app to deliver the real-time data that powers Promoted Delivery. When integrating web frontends with Promoted, you can use our state-of-the-art client libraries to get up and running quickly and correctly. Our libraries are tailored specifically for Promoted Delivery.

The Promoted Delivery API optimizes listings in search, feed, or paid promotions. Call our Delivery API where you would call a database or a search service like Elastic. We re-rank on every request to deliver the best possible listings, personalized to each user and context in real-time. To get your marketplace optimized faster, use shadow traffic to safely train and test our Delivery systems so you can be confident before live production.
