Improve Your Core Web Vitals Page Experience KPIs And Conversion Rate By Making Your Magento 2 Pages Load Faster.
With Resource Hints For Preload Critical Resources & Assets For Better Core Web Vitals And Improved Largest Contentful Paint (LCP) For Your Magento 2 Store!
When your customer visits your store, the browser has to first download the HTML document, parse
the HTML to discover all the resources needed to render the page, and then download these
numerous additional resources and assets such as CSS files, JS files, and images.
This process and loading all these many resources takes time. So when it comes to page load
times and performance KPIs it is important to load critical resources first to make sure
the browser can render the page for your customers as fast as possible.
Even more so since Google introduced the new Core Web Vitals (CWV) KPIs for measuring
performance, with a stronger focus on user experience and fast rendering. For example,
the Largest Contentful Paint (LCP), one of these Core Web Vitals, is in most cases
dependent on the biggest image above-the-fold, also called "Hero-Image".
So it is important to tell the browser which resources and assets are "critical" for rendering
and should be loaded first. When done right, making the browser download the right assets
first, is a great chance to improve page loading speed, especially regarding CWV and
Largest Contentful Paint.
Don't miss on this opportunity to significantly speed up your site and improve your
performance KPIs such as LCP that are part of the page experience ranking signals used
by Google.
Already did all the common performance optimizations in your Magento 2 store, but still not fully happy with your page load times and performance scores? Want to optimize your Largest Contentful Paint KPI for passing the Core Web Vitals test?
Then it is time to give your Magento 2 store another speed bump for improved page loading times by using resource hints for preloading all the critical resources and assets on your site.
Preloading via resource hints is a means of prioritizing which resources and assets are required or important for the browser to render and show a website as fast as possible. So instead of letting the browser first download the HTML, then parse and discover the resources on the page and only then start downloading them, we tell the browser: "Hey dear browser, you need this important thing shortly, please download it right away". By using this neat little trick you can realize some significant gains regarding page speed and specifically for example regarding your Largest Contentful Paint (LCP) score.
Preload Hero-Images / Largest Contentful Paint elements:

Extension for
Magento 2 by JaJuMa In Detail.
Allows You To Control Your Magento 2 Waterfall.
Let The Browser Know What's Really Important To Load First For Improved Core Web Vitals Via Resource Hints.
Resource Hints tell the browser what needs to be fetched sooner because its important for rendering the
page.
One typical candidate for preloading is usually the LCP element/image.
JaJuMa Preload Critical Resources & Assets allows you to preload your LCP
element on product pages, the first product image in media gallery, on category pages, the category
image, automatically or via manual configs for category pages and CMS pages. For category and CMS pages you
can even configure responsive images to be preloaded depending on clients device. By this the browser will
only preload the matching image, for mobile or for desktop devices.
Additionally, with our extension you
can configure global preloads/prefetch/preconnects/early hints for critical assets such as JS,
CSS or Font files, that are applied to all pages on your site.
To make things even better, if
you are using our WebP Optimized
Images or Ultimate Image
Optimizer extension, always the best available image format will automatically be preloaded, WebP,
AVIF and even high-resolution & responsive images will be considered and downloaded by browsers as supported
by clients device.
DNS prefetching tells the browser to perform a DNS lookup for the configured domain in the background.
DNS Prefetch minimizes latency as the DNS lookup has already taken place once the download of a resource from this domain starts.
Preconnect tells the browser to setup a full connection to configured domain in the background, including DNS lookups, TLS negotiations, TCP handshakes.
Preconnect minimizes latency by eliminating costly roundtrips before the download of a resource from this domain starts.
Preload tells the browser to fetch a resource that will be used on current page.
Preloading ensures e. g. a JS/CSS file that would otherwise be discovered only late, will be already loaded and available when required for rendering the current page.
Prefetching tells the browser to fetch a resource with low priority and save it in cache
Prefetched resources will be then already available when the user visits a page later that requires this file.
Indicate to the browser to load a resource as soon as possible. Early Hints sends preload hints to the browser ahead of a final response.
Allowing it to start fetching critical resources (e.g., fonts, CSS, JavaScript) immediately,
even before main document was loaded.
(This option only works for sites running on Cloudflare)
For the Homepage and each CMS Page, the extension allows to manually configure the LCP element to be preloaded manually.
Optionally, it is also possible to preload responsive images, for Desktop and Mobile view.
Same as for CMS Pages, you can configure the LCP element for Category Pages manually, including responsive images.
Alternatively, if no image is configured manually, you can choose to automatically preload the category image or first grid item image automatically.
For Product Detail Pages, you can enable to automatically preload the first product image in media gallery.
