About
AdChoices is a self-regulatory standard for online interest-based advertising that gives consumers enhanced control over the collection and use of their data to deliver relevant ads.
The rel="dns-prefetch" attribute on 
HTML <link> elements instructs web browsers to resolve domain names for external resources before those resources are requested.
It is commonly used for third-party domains serving scripts, fonts, analytics, advertisements, or media files, helping reduce DNS lookup latency and improve loading performance for external connections.
