Definindo o Experimento: Achar Lojas com Precisão
a validação confirma, Para otimizar a experiência de busca de lojas na Shopee, podemos conduzir um experimento A/B focado em diferentes abordagens de pesquisa. A formulação da hipótese central a ser testada é: ‘A apresentação de filtros de busca mais detalhados expandirá a taxa de conversão (adição de itens ao carrinho) nas páginas de lojas’. Para validar essa hipótese, definimos como métrica de sucesso o aumento percentual na taxa de conversão e a redução na taxa de rejeição das páginas de lojas.

O grupo de controle terá a interface de busca padrão da Shopee, sem alterações. Por outro lado, o grupo experimental receberá uma interface com filtros adicionais, como faixa de preço dos produtos, avaliações específicas (ex: ‘excelente’, ‘excelente’) e opções de frete. A duração do experimento será de 14 dias, um período suficiente para coletar um volume de informações representativo e minimizar o impacto de flutuações sazonais. Os recursos necessários incluem o tempo de desenvolvimento para executar os filtros adicionais e a capacidade de monitoramento da plataforma para acompanhar as métricas.
Implementação e Análise: O Caminho da Descoberta
Imagine a busca como um rio, onde os filtros são as comportas que direcionam o fluxo. Para executar nosso experimento A/B, precisamos garantir que a amostra de usuários seja aleatória e representativa da base total. A divisão será 50% para o grupo de controle e 50% para o grupo experimental. A explicação detalhada da interface com os filtros adicionais é crucial: os usuários do grupo experimental observarão, na página da loja, opções para filtrar produtos por preço (ex: ‘até R$50’, ‘R$50-R$100’), avaliação média (ex: ‘4 estrelas ou mais’) e tipo de frete (ex: ‘frete grátis’, ‘entrega rápida’).
Vale destacar que o propósito não é apenas adicionar filtros, mas também torná-los intuitivos e fáceis de empregar. É fundamental compreender que a coleta de informações será automatizada, registrando o número de adições ao carrinho, a taxa de rejeição e o tempo médio de permanência na página para ambos os grupos. A análise comparativa desses informações revelará se a hipótese foi validada e qual o impacto real da nova interface.
Resultados e Próximos Passos: Decisões Estratégicas
Após a inferência do experimento, a análise dos informações fornecerá insights valiosos. Se a taxa de conversão do grupo experimental for significativamente maior que a do grupo de controle (com um nível de significância estatística aceitável), a nova interface com filtros adicionais será implementada para todos os usuários da Shopee. Um exemplo prático: suponha que o grupo de controle tenha uma taxa de conversão de 5%, enquanto o grupo experimental atinja 8%. Esse aumento de 60% pode justificar a implementação da nova interface.
Outro aspecto relevante é a análise da taxa de rejeição. Se a nova interface reduzir a taxa de rejeição, isso indica que os usuários estão encontrando os produtos desejados com mais facilidade. Caso os resultados sejam inconclusivos, ou até mesmo negativos, será necessário revisar a formulação dos filtros e conduzir novos testes. A jornada revela que a experimentação contínua é essencial para aprimorar a experiência do usuário e otimizar os resultados na Shopee. Recursos adicionais podem ser alocados para a criação de tutoriais em vídeo explicando o uso dos novos filtros, maximizando assim sua adoção e impacto.
