User agent di Google Read Aloud
Google-Read-Aloud
è lo user agent per il servizio Google Read Aloud. Questo servizio consente la lettura di pagine web tramite la sintesi vocale (TTS) e viene attivato quando un utente finale ha attivato la sintesi vocale e visita una pagina. Il servizio Read Aloud è utilizzato da Google Go, Google Read it, Read Aloud nell'app Google e altri servizi di sintesi vocale di Google.
Frequenza e comportamento della scansione
Google Read Aloud viene attivato da una richiesta dell'utente; il servizio conserva larghezza di banda memorizzando nella cache i risultati della pagina, ma potresti comunque visualizzare più richieste per una determinata pagina.
Google Read Aloud non è un web crawler: viene attivato su richiesta dell'utente e non segue i link. Una richiesta dell'utente per l'ascolto di una pagina web può generare o meno visite alle pagine, a seconda che questa sia stata recuperata di recente.
Impedire a Google Read Aloud di accedere ai contenuti
Poiché l'avvio di Google Read Aloud avviene tramite un utente, non a seguito di una scansione web automatizzata, non puoi disattivarlo utilizzando un file robots.txt. Per disattivare completamente Google Read Aloud, utilizza il
meta tag nopagereadaloud:

This service enables reading web pages using\ntext-to-speech (TTS). This service is activated when an end user has TTS enabled and visits a\npage.

Google Read Aloud conserves bandwidth by\ncaching page results, but you may still see multiple requests for a given page.\n\n\nGoogle Read Aloud is not a web crawler: it is activated upon user request, and it doesn't follow\nlinks.
