Code from other people's servers.
WHAT COUNTS
Analytics Chat widgets Social media embeds Advertising Fonts loaded from elsewhere Video embeds Review widgets
WHY THEY MATTER
Each is a request to a server you do not control.
If that server is slow, your page is slow.
WHAT TO AUDIT
List every third-party script on your site.
For each, ask whether it earns its place.
WHAT PEOPLE FIND
Analytics from a service they stopped using Chat widgets nobody answers Social embeds pulling in enormous amounts of code
THE CHAT WIDGET POINT
An unanswered chat widget is worse than none, and it costs loading time.
FOR FONTS
Loading fonts from elsewhere adds requests. Hosting them on your own server is faster.
FOR VIDEO
An embedded video can load a great deal before the visitor presses play.
Use a facade that loads the player only on click.
WHAT TO REMOVE
Anything you cannot justify.
