Optimise Core Web Vitals: 5 Store Speed Gains

Understanding Core Web Vitals: What You Need to Know

Have you ever clicked on a website and then waited - and waited - for it to load. It’s annoying. And I think most people don’t really have time for that anymore.

It seems like the truth is that loading speed can actually make or break a website, and google does pay attention. The way I see it, that’s why if you want your site to rank, the best place to start is seemingly with web vitals. Core web vitals are, as the name implies, metrics that matter the most.

They determine how well your store is performing and how accessible it is. In my experience, they also help understand how well users can access your pages and interact with your content.

This is quite important when you’re running an ecommerce store because the aim is to have more people on your website so you can generate more sales. There are three important factors to look out for when thinking about core web vitals. First Contentful Paint (FCP) refers to the amount of time it takes for content to start loading as soon as a user opens the page.

Largest Contentful Paint (LCP) measures how long it takes for a page’s largest piece of content to load - this could be text, an image, or even a video. Cumulative Layout Shift (CLS) looks at how much content shifts as a page loads while Interaction to Next Paint (INP) determines how quickly a page responds when someone interacts with it by clicking, tapping or pressing a key. In essence, core web vitals offer a lot of insight into what’s working and what’s not, giving you the chance to fix things before they become an issue. That being said, it also pays off to constantly keep track of your website performance so you’re always aware of what needs changing or improving.

At the end of the day, it just makes sense if you want your website visitors and customers to have a good experience every time they land on your store.

Key Metrics for Measuring Store Speed

How long do you think it takes for a person to lose interest when a website doesn’t load. It’s something like two seconds, and then they’re on their phones, checking the weather or replying to work emails. Their attention span is just as short as yours is.

And that means that if you have an e-commerce store, keeping it up and running is important - but so is speed. So how do you know if your site loads quickly. How fast is fast enough. That’s why companies came up with Core Web Vitals and metrics.

Sort of. These aren’t long, elaborate numbers that need a maths degree to decipher - they’re plain English numbers, based on what you see. Like Largest Contentful Paint (LCP), which measures how long it takes for the biggest thing on your site to load - and be visible to everyone. Or First Input Delay (FID), which measures how long before the site reacts to any button or menu being clicked.

There’s also Cumulative Layout Shift (CLS), which measures whether things jump around as they're loading. But before anyone asks: No, you don’t have to remember all of these terms. Use them as reference points when figuring out how fast your site can be.

These numbers are measurable with tools like PageSpeed Insights and Google Search Console, so even if you don’t know exactly what each metric means, you can look at the number and know when it feels right. Now that you’ve got some jargon under your belt, don’t rush into trying to fix every metric on your site in one go. Most people tend to focus on LCP because it’s the first thing customers will see. Even if everything else loads well but someone goes blank at first sight - would that be considered a win.

It’s down to personal choice - and the kind of business you run.

Top Strategies to Improve Loading Times

How long does it take for you to abandon a website. For a fair few of us, it’s about 5-6 seconds. And we’re busy these days - so anything slower than that and we’re ready to click away from sluggish landing pages. If you find your bounce rates have been shooting up recently, some people might say it’s because there’s something lacking in your content or products.

That’s not true. It could be something as elementary as poor loading times. You see, customers have almost zero patience now when it comes to using the internet. We’ve all collectively decided that if someone else is able to pull up their website in a second or less, everyone should be able to do that as well.

And if they can’t, they don’t deserve our attention (or money) anymore. And here’s the thing - I’m not sure that is entirely fair but that is how things are now. Most eCommerce platforms like Shopify already offer optimised load speeds but if you’re using plug-ins and tools that are fairly slowing down your store, then you need to change how your site behaves as soon as possible.

Something that works wonders is allegedly having an image CDN (content delivery network) provider and compressing images without losing their quality. Don’t overlook caching on your site either - this holds your resources in place for repeat visits and cuts down on load times by quite a margin. There are many other options but at the end of the day, what matters is constantly testing and reviewing your core web vitals so you never lose out on sales again.

If you’re finding it hard to get the hang of things, there’s no shame in getting help from an expert who knows exactly what will work best for your online store and products.

Enhancing Interactivity for Better User Experience

Have you ever been so engrossed in an online store that you lose track of time. A big part of what keeps us coming back to our favourite online shops is typically how easy they are to use. Sort of. It’s more than just about how good they look - it’s about their interactivity too.

Websites that encourage users to take action tend to make a better impression. We like sites that are fun, easy to navigate, and intuitive, not ones that make us run around in circles trying to figure out what’s where. When everything works together seamlessly, shopping can feel like being in a really great store - online.

You’re able to browse all the aisles (or pages), take a good look at things, and have all your questions answered by helpful salespeople (or chatbots). That’s probably why online stores with interactive features see much higher levels of engagement. A huge reason for this is because being able to interact with a site makes it more memorable and enjoyable.

People often find themselves adding things to their cart or signing up for mailing lists or even telling their friends about the shop. Even if they don’t end up making a purchase at the time, there’s an increased chance that they’ll come back another day. But when there are issues with performance and responsiveness, people can get annoyed or frustrated with having to wait.

What ends up happening instead is that they’ll just leave. And this isn’t a good sign for anyone - not them or the store. That’s why every second matters when we’re talking about load times. And why optimising your site’s speed is sometimes essential for anyone looking to create an interactive experience for their customers.

Reducing Cumulative Layout Shift for Stability

Ever wondered why some pages seem to jump all over the place just as you’re about to click. Or how fast-moving banners and suddenly-appearing buttons on your store’s website can pretty much make customers want to run away. That’s Cumulative Layout Shift (CLS) in action.

And if your website is making them chase after buttons, you might want to do something about it. What you want is a stable site - one that doesn’t leave users feeling like they're chasing a moving target. The best thing you could do for stability is seemingly define dimensions for images, videos, and embeds.

This simple act of telling browsers what space these elements will take up helps browsers avoid reshuffling content when your site starts loading. If you think about it, it seems obvious that setting size attributes for visuals isn’t just handy for browsing but also for clarity. CLS can also be caused by late-loading elements like fonts, ads, or pop-ups. When these load after a visitor has already started interacting with your page, it’s rather disorienting to experience content being pushed around.

More or less. Avoid this by preloading fonts and reserving space for pop-ups and banners using CSS or HTML. Some platforms like Shopify have built-in fixes for these issues - check if there’s an automated way of optimising this because it saves you valuable time.

If you’re unsure whether content on your page moves around during load time, try clicking through your store pages on a different device or browser than the one you use most often. There are endless tools out there that can help you test things out but sometimes, good old physical testing works best - especially if you’re new to all this talk of optimising web vitals.

Tools and Resources for Monitoring Performance

Ever wished you could channel your inner Big Brother to see how your online store is really performing. Tracking things can be a bit of a drama - no one tells you how much time goes into all that number crunching, way after launch day. Sort of.

There are a few tools out there that make it less painful, though. Now, it’s not like catching the perfect wave every single day – but site monitoring tools are sort of the closest we’ll get to a magic wand in the digital world. Google Lighthouse and PageSpeed Insights are the go-to’s for store performance tracking.

Tackle Core Web Vitals - these are a set of three key metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) – to keep an eye on your overall speed and user experience. Then there’s Hotjar and Crazy Egg for behaviour analytics that give valuable insight into how users interact with web pages. Something I realised fairly early on is usually that using more than one tool is always a good idea if you want to pick up every little detail; there’s no such thing as too many numbers. It appears to be very much a case of throwing resources at the wall and seeing what sticks - with good reason.

Tools like Hotjar allow you to spot pain points by tracking something simple, like mouse movements or clicks. Even heatmaps on websites have their use in understanding what features customers love interacting with, so you can leave those alone, and improve the ones they’re not drawn to right away. Don’t forget about regular audits. Pop over to Google Search Console regularly and see if users have reported issues on mobile or desktop devices.

More or less. Google treats website trouble reports in earnest, so keep crawling errors down by fixing all user-reported issues before they snowball into bigger trouble later on. As far as resources go, performance monitoring seems like another checklist item but can make a massive difference to customer journeys if done right.

More or less.
