Developers and businesses use Actors to discover, combine, and automate **ready-to-run cloud applications** for web scraping, browser automation, data extraction, and **agentic coding workflows**. With **more than 50,000 Actors** available and thousands of new ones added every month, helping users quickly find the right Actor has become a critical part of the platform experience. As the marketplace expanded, Apify needed search and recommendation capabilities that could scale with its **rapidly growing catalog** while delivering personalized discovery from the very first interaction. +15% Actor Runs (existing users) Personalized Search +6% Subscriptions (new users) Personalized Search +9% CTR on First Four Search Results (existing users) Personalized Search +12% Overall CTR Actors For You ### Situation Apify's marketplace was growing rapidly, expanding from thousands to **tens of thousands of Actors**. Existing discovery relied primarily on **keyword search**, making it increasingly difficult to surface the most relevant Actors as the catalog expanded. At the same time: * Search infrastructure **limited personalization** * Dynamic ranking at scale became **increasingly difficult to maintain manually** * Recommendation experiences were missing entirely * The team needed a **solution that continuously optimized recommendations without manual intervention**, while still allowing **full control over business rules and personalization strategies** ![](https://www.recombee.com/img/case-studies/apify-situation.png) ### Objectives * Deliver **personalized search results** at marketplace scale * Introduce **recommendations across key discovery journeys** * Increase Actor usage and subscriptions * **Reduce engineering effort** required to optimize ranking * Support rapid marketplace growth without sacrificing relevance ### Solution **Personalized Discovery at Scale** Recombee combines behavioral signals, real-time interactions, and contextual relevance to personalize search results and recommendations across the marketplace. As users explore more Actors, personalized suggestions continuously improve, making discovery more relevant with every interaction. **Search and Recommendations in One Platform** Apify uses a single platform to power both personalized search and recommendations. This enables a consistent discovery experience across search, homepage recommendations, similar Actors, and other touchpoints while simplifying implementation, configuration, and ongoing optimization. **Flexible Configuration Without Heavy Engineering** Using Recombee's Scenario Settings, Apify can independently configure ranking logic, filters, boosters, and recommendation strategies for different search and discovery experiences. This gives the team the flexibility to experiment, optimize, and adapt individual user journeys as the marketplace evolves without extensive engineering effort. **A Collaborative Partnership** Beyond the technology, Apify valued Recombee's hands-on collaboration throughout implementation. Direct access to the engineering and support teams enabled rapid iteration, quick problem solving, and continuous optimization as new discovery challenges emerged. ### Benefits & Results Personalised Search #### New Users **+3%** Actor Runs **+6%** Subscriptions **+7.5%** CTR on First Four Results **+4.5%** Overall CTR #### Existing Users **+15%** Actor Runs **+9%** CTR on First Four Results **+5%** Overall CTR Similar Actors #### New Users **+8%** Actor Runs #### Existing Users **+6%** Actor Runs Actors For You **+12%** Overall CTR \* Results were measured separately for **new users** (with limited behavioral data) and **existing users** (with established interaction history). The primary KPI, **Actor Runs**, measures how often users execute an Actor, making it a key indicator of successful discovery and engagement. ### Recombee’s Solution in Action ![apify](https://www.recombee.com/img/case-studies/scenarios/apify-1.png) #### Search Personalization Personalized Search Instead of returning identical search results for every user, Recombee personalizes ranking using **behavioral signals, user preferences, and real-time interactions**. As users continue interacting with the marketplace, search results become increasingly relevant while still respecting textual relevance and business rules. **Key Benefits** * **Personalized homepage** discovery * **Faster exploration** of relevant Actors * **Better engagement** with recommended content * **Higher** click-through rates ![apify](https://www.recombee.com/img/case-studies/scenarios/apify-2.png) #### Similar Actors You Might Also Like When users open an Actor detail page, Recombee recommends relevant alternatives and complementary Actors based on **behavioral similarity and content understanding**. This helps users quickly discover **better-fitting solutions** while **increasing exploration** across the marketplace. **Key Benefits** * **Improve** Actor discovery * **Surface** relevant alternatives * **Increase** Actor usage * **Reduce** dead ends in user journeys ![apify](https://www.recombee.com/img/case-studies/scenarios/apify-3.png) #### Dashboard Personalization Actors For You The personalized homepage recommends Actors based on **user interests, previous interactions, and evolving usage patterns**. **Recommendations adapt continuously** as users explore new Actors, creating a tailored marketplace experience for every visitor. **Key Benefits** * **Personalized homepage** discovery * **Faster exploration** of relevant Actors * **Better engagement** with recommended content * **Higher** click-through rates “As our marketplace grew to tens of thousands of Actors, delivering relevant discovery became increasingly challenging. With many Actors matching the same search queries, we needed more than keyword-based search. We needed smart personalization that could scale. Recombee helped us roll out personalized search and recommendations across key discovery journeys, and we quickly saw measurable improvements. Among existing users, Actor Runs increased by 15% and click-through rate on the top four search results increased by 9%, along with a 6% uplift in subscriptions from new users. Beyond the technology, what really stood out was the collaboration. The Recombee team genuinely cared about helping us solve difficult problems, worked closely with us throughout implementation, and was always willing to explore solutions together.” ![Jan Kuzelik](https://www.recombee.com/img/case-studies/testimonials/apify.png) **Jan Kuzelik** Product Manager ![Apify](https://www.recombee.com/img/logos/apify.svg) ### About Apify Apify is building the world's largest marketplace of **tools for AI, known as Actors**, powering the next generation of **AI agents and autonomous AI applications**.
