Overview<\/h2>\n\n\n\n
Third-party code consists of analytics services, advertisements and other elements that are served from an external domain URL.<\/p>\n\n\n\n
These resources are often responsible for poor web performance, as they may contain scripts that prevent other tasks from being performed.<\/p>\n\n\n\n
They may also slow down your page for several other reasons including slow DNS lookups, server response errors, slow server response times, among others, which can impact your page performance.<\/p>\n\n\n\n
<\/p>\n\n\n\n
How to reduce the impact of third-party code?<\/h2>\n\n\n\n
1) Reviewing your website’s third-party scripts<\/h3>\n\n\n\n
They help you identify and evaluate scripts and services that pop up on your webpage. We suggest only keeping third-party scripts and services that are actually adding value to your website and to remove all others.<\/p>\n\n\n\n
a) Deferring the loading and parsing of JavaScript<\/h4>\n\n\n\n
Defer the parsing or loading of third-party JavaScript to reduce the initial download size, allowing other resources to be downloaded as well.<\/p>\n\n\n\n
b) Establishing early connections to required origins<\/h4>\n\n\n\n
Use preconnect<\/code> and dns-prefetch<\/code> to establish early connections to important third-party origins.<\/p>\n\n\n\n
c) Lazy-loading third-party resources<\/h4>\n\n\n\n
Lazy-load embedded third-party resources, especially, ones that are not above-the-fold to speed up page load.<\/p>\n\n\n\n
d) Optimize third-party hosting<\/h4>\n\n\n\n
There’s more than one way to optimize third-party hosting. Self-host third party scripts to reduce DNS lookup and round-trip times, improve http caching headers, and take advantages of HTTP\/2 server push.<\/p>\n\n\n\n
