Onefootball provides three types of custom app content:\nraw data such as match scores; user-generated content (UGC), such\nas tweets; and content created by their newsroom and bloggers.\n\n*** ** * ** ***\n\n##### Challenge\n\nOne feature Onefootball tested was a Top News section on the app's\nNews stream. Before releasing it, they wanted to determine whether\nboosting engagement with a collection of news content above the\nfold might inadvertently lower revenues. Specifically, they\nworried that users would simply stop at the news they were keen to\nread, without scrolling further. If so, the app would see less\nrevenue from the digital ads that were critical to the business. \n\n*** ** * ** ***\n\n##### Solution\n\nOnefootball first wanted to test whether their Top News\nfeature would increase engagement, as measured by articles\nread per user. If the answer was yes, they next wanted to know\nwhat the feature should look like. What design was best---one\nwith a rich content UI, or one with fewer words and more\nvisuals? They tested the UI using three groups. The control\ngroup saw no Top News section. Variation A saw Top News and a\nteam-specific section, with more visual details on each news\nitem to attract more attention. Variation B saw only Top News\nand a team specific section.\n\nBy using Remote Config and Firebase Analytics, Onefootball was\nable to prove that higher engagement didn't hurt revenues and\nthat Variation B's cleaner UI worked best. \"Remote Config is\ncrucial for us because we can't really get meaningful\nconclusions without it,\" says Maxime Blanc-Strauss,\nOnefootball's head of product. The testing process took just\nseven days. Now, app users who see the Top News section read\nmore news than before. \n\"Testing features first using Firebase helped us to make the\nright decision, which resulted in an increase of user daily\nengagement by five percent,\" Blanc-Strauss says. In addition,\nthe number of Onefootball articles read per user rose six\npercent. These are excellent scores in any league.\n\n*** ** * ** ***\n\nResults\n\n5% higher sessions per user\n\n6% more articles read per user\n\n16% increase in high quality content consumption \n\n\"Testing features first using Firebase helped us to make the right decision, which resulted in an increase of user daily engagement by five percent.\"\n\n\n- Maxime Blanc-Strauss, head of product, Onefootball \nTry Firebase today\n\n\nIntegrating it into your app is easy.\n[Get started](https://console.firebase.google.com/) \n\n#### All Firebase products\n\n##### Build\n\n- [App Check](/products/app-check)\n- [App Hosting](/products/app-hosting)\n- [Authentication](/products/auth)\n- [Cloud Functions](/products/functions)\n- [Cloud Storage](/products/storage)\n- [Data Connect](/products/data-connect)\n- [Extensions](/products/extensions)\n- [Firestore](/products/firestore)\n- [Firebase ML](/products/ml)\n- [Genkit](https://genkit.dev/)\n- [Hosting](/products/hosting)\n- [Realtime Database](/products/realtime-database)\n- [Firebase AI Logic client SDKs](/products/firebase-ai-logic)\n\n[Generative AI](/products/generative-ai) \n\n##### Run\n\n- [A/B Testing](/products/ab-testing)\n- [App Distribution](/products/app-distribution)\n- [Cloud Messaging](/products/cloud-messaging)\n- [Crashlytics](/products/crashlytics)\n- [Google Analytics](/products/analytics)\n- [In-App Messaging](/products/in-app-messaging)\n- [Performance Monitoring](/products/performance)\n- [Remote Config](/products/remote-config)\n- [Test Lab](/products/test-lab)"]]
