Du m\u00f6chtest wissen, was diese Variante so besonders macht? Dann ist dieser Blogbeitrag wie f\u00fcr dich gemacht!<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Was ist ein Multi-Armed Bandit Test?&nbsp;<\/h3>\n\n\n\n<p>Der Mulit-Armed Bandit Test ist im Vergleich zum A\/B- und MV-Test eine noch sehr junge Testart und wird im E-Commerce noch nicht lange eingesetzt. Sie ist dynamisch und nicht statisch, hei\u00dft, dass w\u00e4hrend der Testdauer die Ressourcen dynamisch an die Testgruppen angepasst werden und die Testgruppen-Verteilung nie gleich bleibt.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">So funktionieren Multi-Armed Bandit Tests<\/h3>\n\n\n\n<p>Wie wir im ersten Teil dieser Blogreihe gelernt haben, geht es beim A\/B-Testing darum, zwei verschiedene Varianten gegeneinander zu testen und beim MV-Test darum, mehrere Varianten miteinander zu vergleichen. Dabei ist die Verteilung der Testgruppen immer fest vorgegeben. Der MAB-Test kann zwei, aber auch mehrere M\u00f6glichkeiten gegeneinander testen, allerdings kann er etwas, das die anderen Tests nicht k\u00f6nnen: Er optimiert sich kontinuierlich selbst. Je nach Leistung der Varianten lenkt er mehr Traffic zu der Option, die f\u00fcr den einzelnen User vielversprechender wirkt. Denn der MAB-Test beruht auf einem lernenden Algorithmus, der auf Basis der Daten, die w\u00e4hrend der Testphase gesammelt werden, Besucher zuweist.<\/p>\n\n\n\n<p>Der Begriff \u201eMulti-Armed Bandit\" stammt aus der Spieltheorie und zielt auf die Arme von verschiedenen Spielautomaten ab. Der Test versucht stetig herauszufinden, welcher \u201cArm\u201d die h\u00f6chste Gewinnsumme bringt und passt das \u201cSpiel\u201d dementsprechend an.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Wieso solltest du auf Multi-Armed Bandit Tests setzen?&nbsp;<\/h3>\n\n\n\n<p>Gerade im Onlinehandel ver\u00e4ndert sich das Verhalten deiner User stetig. Als Onlineh\u00e4ndler musst du darauf so schnell wie m\u00f6glich reagieren, um auch weiterhin der Konkurrenz standhalten zu k\u00f6nnen. So erkennt der Test, dass ein User nicht wie gewohnt mit einer Variante interagiert und spielt daher dann eine andere Version bevorzugt aus. Da du den Test unbegrenzt laufen lassen kannst, bekommt jeder Nutzer immer das angezeigt, was seinen Bed\u00fcrfnissen und W\u00fcnschen am meisten entspricht. So kannst du die Usability und die User Experience in deinem Shop steigern.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Wann ist der Einsatz sinnvoll?<\/h3>\n\n\n\n<p>Gerade in Umgebungen mit sehr viel Traffic und sich stetig \u00e4ndernden Bedingungen kann der MAB-Test sinnvoll sein. Durch seine Zeiteffizienz erm\u00f6glicht er es dir, innerhalb k\u00fcrzester Zeit auf die ver\u00e4nderten Bed\u00fcrfnisse deiner Kunden einzugehen. Sind in deinem Shop also schnelle Entscheidungen und stetige Optimierung ein Muss, kann dir diese Testvariante optimal weiterhelfen.&nbsp;<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>","protected":false},"excerpt":{"rendered":"<p>Im heutigen Blog wollen wir dir eine sehr junge aber effektive Testart vorstellen: Multi-Armed Bandit Testing.
