Don’t be overwhelmed by the table below; most optimizations can be easily achieved with an optimization plugin. I personally use the free Speed Optimization plugin that comes bundled with SiteGround’s Hosting plan. However, there are several other options, including W3 Total Cache (W3TC), WP Rocket, and FlyingPress.

Implementing this feature can be achieved by using an Optimization Plugin:
Third-party code encompasses ads, analytics services, and other components that originate from a domain different from your URL domain.
Such resources often contribute to subpar web performance as they can contain scripts that block your main-thread, thereby preventing other tasks from taking place.
There could be various other reasons for them slowing down your page such as sluggish server response times, slow DNS lookups, server response errors, etc., that can negatively impact your page performance.
Therefore, it’s crucial to scrutinize your website code for third-party scripts and minimize their impact as much as possible for better web performance.
When a page loads, the browser has to download and parse the HTML code line by line. It might encounter third-party scripts that tend to block the main-thread.
The effect on the user experience is three-fold:
The above is further compounded if you have multiple third-party requests, which may further exacerbate your page performance.
Although third-party code could be vital for your site’s functionality or business objectives, it’s best to review your third-party content and ensure they are providing value to your site.
Here are some general strategies to reduce the impact of third-party code:
This helps you recognize and assess scripts and services appearing on your webpage. It’s a sound practice to retain only those third-party scripts and services that genuinely add value to your website and remove the rest.
Some of the suggestions include:
Use preconnect and dns-prefetch to establish early connections to important third-party origins. Read more about this in our documentation.
Lazy-load embedded third-party resources, especially those not above-the-fold, to speed up page load time and enhance your page’s perceived performance
Several methods can optimize third-party hosting. For instance, self-host third-party scripts to lessen DNS lookup and round-trip times, enhance http caching headers, and benefit from HTTP/2 server push.
