It is claimed that the more external scripts are installed on the website, the slower the website load is. So most website owners prefer not to install any additional program scripts, although they are necessary; others subvert the load speed.

Yes, this is true. Many external scripts slow down the load speed, worsening the website SEO quality.

Developing the Plerdy marketing platform, our team considered this aspect and the slow down of the load speed that worried the website owners. So it has written the Plerdy script so that it would not slow down the load speed.

We’re using CDN ultra-fast static and dynamic content delivery over a global edge network.
And enable HTTP/3 – Accelerates HTTP requests by using QUIC, which provides encryption and performance improvements compared to TCP and TLS.

Plerdy marketing platform structure and work principle

The tracking code of the Plerdy marketing platform is given below:

When you check the website load speed, the load time is considered the size of all files and JS. So, the lower is the service script “weight’, the faster the website is.

But the script file size is not the only factor that influences the page load speed.

The browser will not load a certain part of the page until all the JS mentioned above are loaded. That is why some pages with a big deal of inner and external scripts are loading so slowly.

Our team has considered this and, as you have noticed, we use the defer attribute in the script structure.


This attribute prohibits loading the Plerdy tracking code until the page with this script is loaded. So the JS will not affect the page load speed as it will run after the page is loaded.

The script load speed after loading the page load is given below:
