According to Backlinko, the average page load standard is 10.3 seconds on desktop and 27.3 seconds on mobile.
If youre not striking these markers, you might have a problem.
Whether youre utilizing Google Optimize or another A/B screening tool, there are a couple of ways to prevent your website from slowing down.
1. Carry out Scripts in the Top of the Head Tag.
When you add A/B testing scripts to your website, make certain they are at the top of your head tag and not a tag supervisor.
This is essential due to the fact that if you make modifications to your website, the scripts will be overwritten.
When you make modifications to your site, a tag supervisor is an external script that loads in place of others which can overwrite them without cautioning and prevent scripts from operating correctly.
If you are using the simultaneous variation of the script, then make certain it is put after your sites scripts..
This will avoid any problems with hold-ups brought on by third-party resources on your page, such as advertisement networks..
2. Usage Asynchronous Tracking.
Google Optimize has 2 versions: asynchronous and concurrent..
The concurrent versions avoid any content from rendering up until it has been fully filled. This can prevent your A/B tests from filling in a reasonable time..
The asynchronous versions avoid any material from rendering up until it is all set, but this does not prevent the other scripts on the page from being executed instantly.
The asynchronous variation is recommended for the majority of users. It loads in a different thread from the remainder of the site, so it does not prevent other important tasks from being executed prior to its execution.
The async variation will avoid certain animations from slowing down your test experiences while still enabling for other components on the page to play..
If you use a tag manager like Google Tag Manager (GTM), or another JavaScript management system, its crucial these are implemented asynchronously and not using the standard version of the Optimize bit..
When Google Optimize is running on your site, there must be no delays in page load time. The async version can avoid this by including asynchronous to each script call so they dont block rendering.
This is especially crucial if you do not run any tests or if they are played in a non-interruptive manner across all pages.
3. Include Animations to Improve UX.
If you are using Google Optimize, then you can also use animations to avoid test experiences that might fill slowly and be too disruptive to the user experience.
Animations can be utilized to avoid A/B testing from slowing down your website by providing users something fun to focus on while they await content delivery.
You can use animations to keep users engaged before a site totally loads, like this.
This will tell users their material is being packed and prevent them from leaving the page.
Remember to constantly focus your animations in a place where your user will be focused.
A packing page is a great example of this or a page where the user will be focused on a specific part of the design.
Remember to avoid animations from interrupting other tests and make sure they are carried out properly across all pages.

When adding a bit to your website, attempt to keep it as little as possible.
This will avoid the script from slowing down other parts of your site, and avoid other scripts on your page from being delayed or disrupted..
You can do this by utilizing a tag manager, such as Google Tag Manager (GTM)..
GTM will enable you to shorten the snippet or include the bit only on particular pages..
Bear in mind that using a tag manager is not needed for Google Optimize if you simply wish to add it as soon as across all of your pages head tags..
If you prefer to embed the script into each page straight then make sure they are executed at the top of the head tag..

When conducting A/B tests on various server sides, the hold-up is often much less noticeable..
You may be utilizing PHP rather of JavaScript on your client-side to avoid material from filling slowly and disrupting users who are trying out their brand-new site style..
Using different server sides works due to the fact that the async version will prevent internet browsers from blocking on a callback function, which would prevent all other content from filling while its waiting on code to end up running..
The benefit of doing this is the server-side tests prevent users with sluggish connections or high latency from seeing hold-ups when filling material..
If you cant do this, its suggested to utilize Google Tag Manager to load these scripts asynchronously so they run after page rendering is total and dont impact performance..
Keep in mind that when screening on different server sides, it might be more difficult to prevent a slower loading experience from interrupting users considering that there is no method of calling asynchronous JavaScript into service..

Variation codes are the code that is utilized by Optimize for each variation..

As soon as on a page it can prevent other scripts from running effectively or even prevent the page from packing at all, if too lots of changes are applied at.
