The digital landscape is a fast-moving beast. One day, we’re obsessing over keyword density, and the next, we’re pivoting toward AI-generated content and semantic search. However, amidst the constant flux of Google’s algorithm updates, one pillar remains remarkably steadfast: the user.
Google’s ultimate goal has always been to provide the best possible answer to a query, but the definition of "best" has evolved. It’s no longer just about the relevance of the information; it’s about the quality of the journey taken to get it. This is where Core Web Vitals come into play. While the initial hype around the 2021 Page Experience Update has subsided, the reality is that page experience is not just a "tie-breaker"—it is a fundamental component of website performance and SEO.
At Anchor Digital, we see too many brands focusing on "the shiny things" while their technical foundations crumble. If your site is a chore to use, it won't matter how good your content is. In this guide, we’re stripping back the jargon and looking at why page experience remains a non-negotiable for organic growth.
Page Experience is Still A Ranking Factor
It is easy to get distracted by the latest AI buzzwords and forget that Google’s "Page Experience" signals are a consolidated set of metrics designed to measure how users perceive the interaction with a web page. This isn't just about passing a test for the sake of it; it’s about meeting a global standard of usability.
Google has integrated these metrics into its core ranking systems. While great content can still rank even with poor page experience, the competitive nature of the modern SERP means you’re leaving money on the table if your site is sluggish. Website performance SEO is about removing the friction between a user’s intent and your brand’s solution. When Google sees a site that loads instantly, responds to clicks without delay, and doesn't jump around while loading, it views that site as a high-quality destination.
Beyond the direct ranking signal, page experience indirectly influences SEO through "user signals." If a user clicks your link and encounters a three-second delay, they bounce. High bounce rates and low dwell times send a clear message to Google: this page didn't satisfy the user.
Understanding Core Web Vitals in Practical Terms
The terminology surrounding Core Web Vitals can feel like an alphabet soup of technical acronyms. To optimise them, we first need to understand what they actually measure in the real world.
Largest Contentful Paint (LCP)
LCP measures perceived load speed. It marks the point in the page load timeline when the main content has likely loaded. To improve LCP score, you aren't just looking at the total load time of the page; you’re looking at how quickly the biggest "above-the-fold" element (usually a hero image or a heading) appears. A "good" LCP is under 2.5 seconds.
Interaction to Next Paint (INP)
Replacing the old First Input Delay (FID) as of March 2024, INP is a more comprehensive metric for responsiveness. It measures the latency of all interactions a user has with a page. If a user clicks a "buy now" button or a mobile menu and nothing happens for half a second, your INP score will suffer. It’s about how "snappy" your site feels.
Cumulative Layout Shift (CLS)
CLS measures visual stability. Have you ever tried to click a link, only for the page to shift at the last second, causing you to click an ad instead? That’s a poor CLS. It happens when elements like images or fonts load asynchronously and push other content around. For a site to be considered stable, it needs a CLS score of less than 0.1.
The Commercial Impact of Speed and Stability
While SEOs talk about rankings, business owners talk about revenue. The beauty of page speed optimisation is that it is one of the few technical SEO tasks that has a direct, measurable impact on your conversion rate.
Research consistently shows that every 100-millisecond delay in load time can decrease conversion rates by up to 7%. Conversely, when brands improve LCP score and overall responsiveness, they see an immediate uplift in engagement. Users who enjoy a fast, seamless experience are more likely to stay longer, view more pages, and ultimately complete a transaction.
In e-commerce, Core Web Vitals are a matter of survival. Mobile users, in particular, have zero patience for layout shifts or delayed responses. If your site isn't optimised for the palm of their hand, they will move to a competitor who is. At Anchor, we treat performance as a revenue driver, not just a technical checkbox.
Why Technical SEO and UX Can’t Operate in Silos
Historically, SEO and Web Development were often at odds. The SEO team wanted more content and tracking scripts, while the developers wanted a clean, lightweight codebase. Today, that divide is disappearing. Website performance SEO requires a unified approach.
User Experience (UX) is no longer just about how a site looks; it’s about how it works. A beautiful design that takes 8 seconds to load is, by definition, bad UX. Similarly, a fast site that is impossible to navigate fails the user just as badly.
To win in 2026, your "creative" and "performance" teams need to speak the same language. This means:
- Designers understand the impact of massive, unoptimised images on LCP.
- Developers understand how render-blocking JavaScript affects INP.
- SEO Specialists understanding that pushing for more "widgets" might actually hurt the site’s ability to rank.
Common Performance Bottlenecks Holding Websites Back
Most sites struggle with the same handful of issues. If you’re looking to get your vitals into the "green," these are usually the first places to look:
- Unoptimised Images: Large, high-resolution hero images are the #1 killer of LCP. Using modern formats like WebP and implementing lazy loading are essential steps in page speed optimisation.
- JavaScript Execution Time: Third-party scripts (chatbots, tracking pixels, heatmaps) can bloat your site. Each one adds a "tax" to your site's responsiveness.
- Lack of Image Dimensions: If you don't tell the browser how much space an image will take up before it loads, the browser has to guess. When the image finally arrives, it "pushes" the text down, ruining your CLS.
- Server Response Times: If your hosting is subpar, it doesn't matter how optimised your front end is. A slow Time to First Byte (TTFB) will drag down every other metric.
A Strategic Approach to Core Web Vitals Optimisation
At Anchor Digital, we don't believe in "plug-and-play" SEO. Optimising for Core Web Vitals requires a bespoke strategy based on your specific tech stack and business goals.
Step 1: Audit and Baseline
Use tools such as PageSpeed Insights and Chrome User Experience (CrUX) reports to understand how real users experience your site. Don’t just look at the homepage; look at your highest-value conversion pages.
Step 2: Prioritisation
Not every fix is worth the development hours. Identify the ‘low-hanging fruit,’ such as implementing a Content Delivery Network (CDN) or compressing images, that will deliver the biggest boost to your website's performance and SEO with the least friction.
Step 3: Improving the LCP Score
Evaluate critical CSS and preloading strategies to ensure the most important elements of your site are delivered to the user's screen instantly.
Step 4: Continuous Monitoring
Performance isn't a "one and done" task. Every time you add a new plugin or a blog post, your vitals can shift. Implement monitoring systems to ensure your site remains fast, stable, and responsive well beyond the initial optimisation.
