Caricare il tag annuncio in modo asincrono

Panoramica
Questo controllo garantisce che gli script della libreria di tag annuncio vengano caricati in modo asincrono.
Per impostazione predefinita, l'esecuzione di JavaScript è sincrona. Ciò significa che, una volta che uno script
, nessun altro contenuto può essere caricato finché lo script non è stato
scaricati, analizzati ed eseguiti. L'attivazione dell'esecuzione asincrona impedisce
questo, consentendo al browser di continuare a elaborare altre risorse mentre
lo script specificato viene caricato in background. In questo modo la pagina rimane reattiva
durante il caricamento degli script e riduce il tempo necessario per caricare tutte
componenti.
Consigli
Includi l'attributo asincrono nella definizione del tag script. Ad esempio:
AdSense
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
AdSense (annunci automatici)
<script async data-ad-client="ca-pub-xxxxxxxxxxxxxxxx" src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
Tag publisher di Google
<script async src="https://securepubads.g.doubleclick.net/tag/js/gpt.js"></script>
Sono supportati i seguenti script della libreria di tag annuncio:
| Libreria di tag annuncio |
Script |
| AdSense |
pagead2.googlesyndication.com/pagead/js/adsbygoogle.js
pagead2.googlesyndication.com/pagead/show_ads.js
|
| Tag publisher di Google |
googletagservices.com/tag/js/gpt.js
securepubads.g.doubleclick.net/tag/js/gpt.js
|
Inizia a utilizzare i tag publisher di Google

This is achieved by including the `async` attribute within the `\u003cscript\u003e` tag. Asynchronous loading allows the browser to continue loading other page content while the script downloads and executes in the background. Supported ad tag libraries include AdSense and Google Publisher Tag, with specific script URLs like `pagead2.googlesyndication.com/pagead/js/adsbygoogle.js` and `securepubads.g.doubleclick.net/tag/js/gpt.js` needing the `async` attribute.\n"],null,["# Load ad tag asynchronously\n\nOverview\n--------\n\nThis audit ensures ad tag library scripts are loaded asynchronously.\n\nBy default, JavaScript execution is synchronous. This means that once a script\nis encountered, no other content can be loaded until that script has been\ndownloaded, parsed, and executed. Opting into asynchronous execution prevents\nthis, allowing the browser to continue processing other resources while the\nspecified script is loaded in the background. This keeps your page responsive\nwhile scripts are loading and decreses the time necessary to load all critical\ncomponents.\n\nRecommendations\n---------------\n\nInclude the async attribute in the script tag definition.
