Engajamento

Metrica que mede a interacao dos seguidores com o conteudo nas redes sociais

Engajamento (engagement) e a metrica mais importante do Instagram e outras redes sociais. Ele mede o nivel de interacao que os seguidores tem com seu conteudo, incluindo curtidas, comentarios, compartilhamentos, saves e visualizacoes de stories.

Sorteios no Instagram sao uma das formas mais eficazes de aumentar o engajamento. Um post de sorteio tipicamente gera 10-50x mais comentarios que um post normal, pois os participantes precisam comentar marcando amigos. Esse volume de interacoes sinaliza ao algoritmo do Instagram que o conteudo e relevante, aumentando seu alcance organico.

O SorteiGram ajuda marcas a maximizar o engajamento dos sorteios com filtros inteligentes que garantem participacoes genuinas (removendo bots e duplicados) e uma revelacao cinematografica que gera conteudo compartilhavel para stories e reels.
