Inserzioni per le destinazioni - Eventi

Le inserzioni per le destinazioni usano quattro eventi. Ogni evento ha un insieme di parametri (lista completa in Dettagli dei parametri degli eventi). Usa il pixel di Meta sul tuo sito web e gli eventi nell'app mobile nella tua app Android e nella tua app iOS. Scopri di più sugli eventi standard e personalizzati.

Pixel di Facebook (per siti web)

Questa guida parte prevede che tu abbia già installato un pixel di Facebook. Se non lo hai fatto, consulta Uso dell'API Marketing con il pixel.

Assicurati che il codice di base del pixel sia già caricato quando attivi un'azione. Se usi uno strumento di gestione dei tag, accertati di inserire il tag contenente il codice pixel in ogni pagina. Il tag deve essere visualizzato prima del tag che contiene il codice azione del pixel. Usa Facebook Pixel Helper per convalidare l'implementazione del tuo pixel.

Dettagli dei parametri dell'evento

Su mobile, i nomi dei parametri sono diversi rispetto al pixel di Meta. Spesso, è presente la preposizione fb_ con poche eccezioni, quali content_ids rispetto a fb_content_id, value rispetto a _valueToSum.

Quando invii più valori (ad es. con content_ids o content_type) fornisci un array di valori JSON codificati: '["value1", "value2"]'. Non concatenare i valori con una virgola.

Nome e tipo di parametroDescrizione

travel_start (pixel)

fb_travel_start (app)

tipo: stringa

Consigliato.

La data di inizio del viaggio dell'utente. Accettiamo date in YYYYMMDD, YYYY-MM-DD, YYYY-MM-DDThh:mmTZD e YYYY-MM-DDThh:mm:ssTZD. Se fornito, puoi usare questo parametro nell'inserzione mediante i modelli di tag e targetizzare gli utenti in base alle loro date di viaggio usando gli intervalli di prenotazione nel tuo pubblico.

Esempi:

  • 20180623
  • 2018-06-23
  • 2017-06-23T15:30GMT
  • 2017-06-23T15:30:00GMT

travel_end (pixel)

fb_travel_end (app)

tipo: stringa

Consigliato.

La data finale del viaggio dell'utente. Per la data accettiamo gli stessi formati elencati per il valore di travel_start. Se fornito, puoi usare questo parametro nell'inserzione mediante i modelli di tag e targetizzare gli utenti in base alle loro date di viaggio usando gli intervalli di prenotazione nel tuo pubblico.

content_ids (pixel)

fb_content_id (app)

tipo: stringa o stringa[]

Consigliato per search, obbligatorio per tutti gli altri.

Qualsiasi ID rilevante riportato nel catalogo dei viaggi, ad esempio per l'evento ViewContent invia l'ID dell'articolo presentato oppure per Search invia un array di ID per i risultati migliori.

Esempi:

  • "1234"
  • '["1234", "2345", "3456"]'

content_type (pixel)

fb_content_type (app)

tipo: stringa o stringa[]
