Hipótese Central: Impacto do Cupom Abrangente
Iniciamos nossa jornada com a formulação da hipótese central: a utilização de um cupom Shopee abrangente em dezembro expandirá significativamente a taxa de conversão de carrinhos abandonados. Para ilustrar, imagine que temos uma loja virtual de eletrônicos. Notamos que muitos clientes adicionam produtos ao carrinho, mas não finalizam a compra. Acreditamos que um incentivo, como um cupom de desconto, pode ser o fator decisivo para concretizar a venda.

Para testar essa suposição, definimos duas versões da página de checkout: uma sem cupom (grupo de controle) e outra com o cupom abrangente (grupo experimental). O cupom oferece 10% de desconto em todos os produtos do carrinho, sem restrições. Vale destacar que a clareza na definição da hipótese é crucial para o sucesso do experimento. Sem uma direção clara, corremos o risco de coletar informações irrelevantes.
Métricas de Sucesso e Grupos de experimento
A métrica de sucesso primária é a taxa de conversão de carrinhos abandonados, calculada como o número de compras finalizadas dividido pelo número total de carrinhos criados. Adicionalmente, monitoraremos o valor médio do pedido e a taxa de retenção de clientes. Um aumento significativo na taxa de conversão, sem uma queda drástica no valor médio do pedido, indicará que o cupom abrangente é eficaz. É fundamental compreender que a escolha das métricas certas é tão crucial quanto a própria implementação do experimento.
O grupo de controle visualizará a página de checkout padrão, sem qualquer menção a cupons de desconto. O grupo experimental, por sua vez, observará a página de checkout com o cupom abrangente visível e aplicável. A divisão dos usuários entre os grupos será aleatória, garantindo que não haja viés na amostra. Outro aspecto relevante é a garantia de que ambos os grupos sejam representativos da base de clientes.
Duração, Recursos e Análise Comparativa
A duração do experimento será de duas semanas. Justificamos esse prazo com base no volume de tráfego do site e na sazonalidade do mês de dezembro, período em que as compras online tendem a expandir. Duas semanas nos fornecerão informações suficientes para uma análise estatística robusta. Em contrapartida, um período mais curto poderia ser afetado por flutuações aleatórias, comprometendo a validade dos resultados.
Os recursos necessários incluem: uma plataforma de experimento A/B (como Google Optimize ou VWO), um desenvolvedor para executar as alterações na página de checkout e um analista de informações para monitorar as métricas e interpretar os resultados. Ao final do experimento, compararemos as métricas de sucesso entre os grupos de controle e experimental. Se o grupo experimental apresentar uma taxa de conversão significativamente maior, confirmaremos a hipótese e implementaremos o cupom abrangente de forma permanente. Por exemplo, se a taxa de conversão expandir de 5% para 7%, isso representará um aumento de 40%, o que seria considerado um desfecho positivo.
