Page Preload/Prefetch for faster or even zero TTFB and
Web Vitals Optimization in Your Magento 2 Store!

The Problem
Page Speed & CWV
Optimization
Eliminate TTFB

Page Speed Optimization for fastest possible page load times - A challenge every website and every Magento 2 store owner is facing, that just got more important with Googles new ranking relevant Core Web Vitals (CWV) KPIs. There are many ways, measures, and options available to improve the page speed for Magento 2. From Code, JS & CSS and Full Page Caching, just to name a few.

However, even with all these common page speed optimizations applied, there is still a certain part of the page load time that remains unoptimized:

The TTFB (Time-to-first-byte) is calculated as

1. Request to Server +
2. Server Processing +
3. Response to Client

No. 2 can be optimized by i. e. code optimizations and Full Page Caching.
But No. 1 and No. 3, simply speaking the time need to request and download a page, mostly or heavily depends on your customer's network and bandwidth.
With customers network latency and slow bandwidth being something we generally have no influence on, there is no easy way to optimize on this.

But wait, take a look at our solution and see how we can help you to tackle these few hundred milliseconds and provide your customers with a super fast and responsive user experience with zero TTFB...

The Solution
Page Preload FOR
Zero TTFB &
Instant Page Load

Even after optimizing your TTFB, it probably still takes up to a few hundred milliseconds for your customers to request and download a page from your Magento 2 store.
Wouldn't it be great to scrape off some of this TTFB time or eliminate it completely? Providing your customers a super fast and responsive shopping experience with literally instant page load when navigating to subsequent pages?
This is what you can do with JaJuMa Page Preload extension. While your customer is reading a page on your site, links on this page get preloaded/prefetched in the background and cached by the browser. When the customer then visits one of these preloaded pages, this page does not need to be downloaded anymore but is available instantly.

With our extension you can flexibly configure and control the preload intensity, triggered only by customer interaction (hover or click a link) or by links being visible to the customer. Additionally, you have the option to configure which links should be preloaded and which links should be excluded from preloading/prefetching via blacklist/whitelist.

Your customers will love this improvement to your store and enjoy the faster and more responsive shopping experience.
But as studies by Amazon and others have shown, removing 100 milliseconds of latency improves sales by 1%, so there is a direct correlation between page load times and sales/revenue.

Don't miss on this business value of removing these few hundred milliseconds from your TTFB with our Page Preload extension.
Especially regarding the Core Web Vitals KPIs, these few hundred milliseconds can make a huge difference and improvement.

Page Preload Extension for Magento 2 by JaJuMa In Detail.
Faster Subsequent Page Loads for Magento 2.
Improve your User Experience and increase the Conversion Rate
in your Online Store!

Actions taking less than 100ms are perceived as "Instant" by the human brain. So how about reducing the TTFB for your Magento 2 to below 100ms or even to 0ms?
With JaJuMa Page Preload you can now get there, make your pages feel instant for your customers, no matter the speed and response time of your server, the distance between your server and the customer, and even on 3G.

The idea of preloading/prefetching pages is actually nothing new. Back in the old days when the internet was still slow, there were first attempts in making surfing the web faster by applying preloading.
Today, page speed is an SEO ranking factor and still a challenge for every Magento 2 store. With the new Core Web Vitals Google increases now once more the importance of performance and usability as ranking factors. Everyone is trying to scrape off the last milliseconds from page load times to improve the user experience and ultimately increase the conversion rate.
So this old idea is back and with JaJuMa Page Preload now also available for Magento 2.

Ready to learn more on how this works and allows you to improve your customer's shopping experience with faster subsequent page loads?

 

Why Should I Use Page Preloading?

Page Preload / Prefetch as Core Web Vitals Optimization:
Via Page Preload reduced TTFB-times directly affect your Core Web Vitals (CWV) Largest Contentful Paint (LCP) KPIs. The benefit won't be visible with lab data as shown e. g. by Google Page Speed, for the ranking relevant field data numbers as reported by your users, however, there will be a direct positive impact.

Never hear about "Page Preloading" or prefetching? No surprise, most page speed optimization guides do not mention this and it's still rather unknown within the Magento world and community. So why should you use it in your Magento store?
Short answer: Because it's a great opportunity to speed up your site.

Being a very small light-weight and drop-in solution, not affecting how your store works, not interfering with your other performance optimizations, and no conflicts with your customizations and being flexibly adjustable to your individual situation, its a no-brainer chance to speed-up your Magento 2 store!

We have been using pre-loading on our website since years, with no issues at all, but great results.
Also Google is backing the idea and concept behind page preloading/prefetching with an own solution named "Quicklink".
Which is similar, but less flexible and less suitable for e-commerce sites compared to JaJuMa Page Preload which is based on "Instant.Page", customized and extended specifically for Magento 2.

Try It!
To See How It Works...

Test your clicking speed


Click the "Test Your Clicking Speed" Button to see how much time it takes from start hover (or start touch) the button until click the button.
With "Hover" being one of the triggers that JaJuMa Page Preload supports for initiating the page preload, the time shown would be the time that can be saved.
Or simply browse this website, any link on this site is preloaded as soon as it is within viewport.
Trigger the preload by viewport is also supported by JaJuMa Page Preload extension.

In Action...



Want to play with all available triggers for preloading available with our extension to control the preloading intensity?
See our extension demo or read the details below...

Configure Preload/Prefetch Intensity

More intense preloading means a higher chance a page is preloaded before your customer visits the page, but also more additional load on your server.
To avoid your server become overloaded by preloading requests, our extension comes with flexible options for fine-tuning the preload intensity based on different preloading triggers.

Following options are available:

  1. On Hover + 65ms (Default):
    Links will be preloaded 65 ms after hovering a link and when a mobile user starts touching their display.

  2. On Hover + Custom Delay:
    Links will be preloaded with custom delay as configured after hovering a link and when a mobile user starts touching their display.
    A lower value means more preload requests, a higher value will reduce the preload requests.

  3. On Mousedown (Desktop Only):
    Links will be preloaded when the user starts pressing their mouse button, right before releasing it.
    Links are only preloaded on Desktop, but not on mobile devices.

  4. On Mousedown:
    Links will be preloaded when the user starts pressing their mouse button, right before releasing it.

  5. When Visible (Mobile only):
    Links will be preloaded as soon as they’re visible on Mobile Devices. On Desktop Default will be used.

  6. When Visible:
    Links will be preloaded as soon as they’re visible. On both, Desktop and Mobile Devices.

Choose the right Preload/Prefetch Strategy:

The “Cautious” Preload Strategy

To avoid any additional load on your server, the “On Mousedown” options would be the way to go, either with preloading happening only on Desktop or on both, Desktop and Mobile.

This will create no unused requests while still improving page loads by around 80ms on average.

The “Balanced” Preload Strategy

For a balanced result between additional requests and improved page speed times, choose the “On Hover” options, either with default delay of 65ms or fine-tuned to your needs with a custom delay.

This may create some unused requests when a user hovers a link, but never clicks to visit this page. But it provides improved page load times by up to a few hundred milliseconds. Check the Click Speed Test Tool above to see how much page load will be reduced for you.

Note:
It is recommended to only use this option with Varnish/FPC (Full Page Cache) enabled and to narrow down the preload scope via Whitelist/Blacklist to only preload pages with a good chance to be visited by customer.

The “All-In” Preload Strategy

For the best result in terms of page speed improvement, choose the “When Visible” options, either only on Mobile (with fewer links in viewport due to smaller screens) and fallback to default on Desktop (= On Hover with default delay of 65ms) or on both, Desktop and Mobile.
Please be aware, since online stores usually have many links on one page, this may create a lot(!) of unused requests which may in the worst case overload your server. However, with this preload strategy, when a customer clicks on a preloaded link, page load will be literally “instant” with zero TTFB (Time To First Byte).

Note:
It is highly recommended to only use this option with Varnish/FPC (Full Page Cache) enabled and to narrow down the preload scope via Whitelist/Blacklist to only preload pages with a good chance to be visited by customer.

Configure Preload Scope & Preload Cache Control (TTL)

JaJuMa Page Preload not only allows control of preload intensity but also the scope where preloading will be used and applied.
Via blacklist or whitelist it can be defined which links should be preloaded or which links should be excluded from preloading. 

This is useful for e. g. following cases:

  • Reduce preload request by avoiding unnecessary preloads
    (for example with layered navigation, that has many links, most of them likely not visited by a customer)
  • Preload only important pages
    (for example focus on only category pages and/or product pages)
  • Exclude pages from preload that should never be cached
    (for example Cart, Checkout, Customer Account)
  • Exclude links from preloading that trigger an action
    (for example Customer Logout Link :-) )

Additionally you can also configure the Cache-TTL (Time-To-Live) for preloaded content. Follow this time the browser will keep any preloaded content in the cache and use it when the customer visits this preloaded content instead of loading it from your server.
