Script di terze parti
Perché è importante
Scripts from other domains (ads, chat widgets, analytics, A/B testing) add DNS lookups, connections and main-thread work you do not control. A slow third party can delay your whole page.
Come risolvere
- Remove tags you no longer use.
- Load the rest with async or defer, or after consent.
- Self-host small libraries instead of loading them from public CDNs.
