Panoramica
Questo controllo consente di verificare se le richieste di header bidding vengono differite o meno fino
Viene caricata la libreria Tag publisher di Google (GPT). Nella maggior parte dei casi, queste richieste non vengono
dipende da GPT e può essere eseguita in parallelo al caricamento della libreria
velocizzando il caricamento degli annunci.
Consigli
Assicurati che le richieste di header bidding non restino in attesa su googletag.pubadsReady()
o
googletag.cmd.push()
.
Esempio Prebid.js
Risposta sbagliata |
window.pbjs = pbjs || {};
pbjs.que = pbjs.que || [];
window.googletag = window.googletag || {};
googletag.cmd = googletag.cmd || [];
googletag.cmd.push(function() {
googletag.pubads().disableInitialLoad();
// Incorrect: Making bid requests dependent on GPT loading.
pbjs.que.push(function() {
pbjs.requestBids({
bidsBackHandler: handleBidResponse
});
});
});

Corretto |
window.pbjs = pbjs || {};
pbjs.que = pbjs.que || [];
// Correct: Making bid requests independent of GPT loading.
pbjs.que.push(function() {
pbjs.requestBids({
bidsBackHandler: handleBidResponse
});
});
window.googletag = window.googletag || {};
googletag.cmd = googletag.cmd || [];
googletag.cmd.push(function() {
googletag.pubads().disableInitialLoad();
});
