Improve website performance, page experience and real-user experience with Core Web Vitals optimisation focused on the technical factors that affect how quickly, responsively and reliably your pages perform.
SEOCompany.me provides Core Web Vitals optimisation services in Singapore for businesses that want to diagnose and resolve performance issues affecting their websites across desktop and mobile devices.
We analyse real-user performance data, PageSpeed Insights, Search Console and technical website factors to identify what is affecting your Core Web Vitals scores. Our recommendations go beyond simply trying to achieve a green score. The objective is to create a faster, more stable and responsive website that supports both users and organic search performance.
Structured data is the broader concept of providing machine-readable information about a webpage.
The current Core Web Vitals focus on three areas:
Largest Contentful Paint (LCP) measures loading performance and how quickly the main content becomes visible.
Interaction to Next Paint (INP) measures responsiveness by assessing how quickly a page responds to user interactions.
Cumulative Layout Shift (CLS) measures visual stability and identifies unexpected movement of page elements while a page loads.
Google evaluates these metrics using real-world user data where available. This means a website can appear fast during an internal test while real users may still experience slow loading, delayed interactions or unstable layouts.
Core Web Vitals optimisation therefore requires understanding both the technical causes and the actual user experience.
Core Web Vitals are part of Google’s broader page experience signals. They should not be viewed as a standalone ranking formula or a guarantee of improved rankings.
However, performance can influence the quality of the experience users have with your website. A page that loads slowly, responds poorly to interactions or shifts unexpectedly can create friction, particularly on mobile devices.
For SEO, Core Web Vitals should therefore be considered alongside technical accessibility, content quality, relevance, internal linking, authority and other established search fundamentals.
Improving performance can also support wider business objectives. Faster and more responsive pages can make it easier for visitors to browse products, complete forms, read content and interact with important elements.
Our approach is therefore to treat Core Web Vitals as part of your wider technical SEO and website performance strategy rather than optimising metrics in isolation.
Every website has different performance problems. A WordPress website may have issues caused by plugins and themes, while an eCommerce website may be affected by large images, third-party scripts, product functionality or complex JavaScript.
Our Core Web Vitals services begin with diagnosis before recommendations are made.
We assess your website's current performance using relevant real-user and laboratory data to understand where problems exist and which pages or templates are most affected.
Our audit can examine LCP, INP and CLS alongside related performance indicators, page templates, mobile performance, JavaScript execution, image loading, CSS, third-party resources and server response times.
Rather than treating every warning as equally important, we identify the underlying causes and prioritise issues according to their likely impact.
Interaction to Next Paint measures how responsive a page is when users interact with it.
Poor INP can be associated with heavy JavaScript execution, long tasks, inefficient event handlers, excessive third-party scripts or complex client-side functionality.
Our INP optimisation process identifies interactions that are taking too long and investigates the code and resources contributing to the delay.
Recommendations may include reducing JavaScript execution, breaking up long tasks, improving event handling, deferring non-critical functionality and reducing unnecessary third-party scripts.
This is particularly important for websites with interactive navigation, filters, forms, calculators, search functions, shopping carts or other dynamic components.
Core Web Vitals performance can vary considerably between desktop and mobile.
Mobile users may have slower network conditions, less processing power and different browsing behaviour. A page that performs well on a high-powered desktop computer may therefore provide a weaker experience on mobile devices.
We analyse mobile performance separately rather than assuming desktop improvements will automatically solve mobile issues.
The optimisation strategy considers mobile loading, responsive images, JavaScript execution, layout stability, server response and other factors affecting mobile users.
Images are often among the largest resources loaded on a webpage.
We review image dimensions, formats, compression, responsive delivery and loading behaviour to identify opportunities for improvement.
For important above-the-fold images, the loading priority may need to be different from images further down the page. Lazy loading can be useful for appropriate resources but should not be applied blindly to content that users need immediately.
Analytics, advertising, chat, social media widgets, heatmaps and other third-party tools can add functionality but may also introduce additional network requests and JavaScript execution.
We identify third-party resources that contribute to performance problems and assess whether they can be removed, delayed, loaded conditionally or configured more efficiently.
The objective is not to remove useful marketing functionality. It is to ensure that non-critical resources do not unnecessarily interfere with the primary user experience.
Largest Contentful Paint measures how quickly the largest visible content element becomes available to the user.
Poor LCP can occur for different reasons. A slow server response, render-blocking resources, oversized images, inefficient loading sequences or excessive client-side processing can all contribute. Our LCP optimisation work focuses on identifying what is delaying the main content and improving the loading path.
Depending on the website, recommendations may involve optimising the LCP image, improving server response, prioritising critical resources, reducing render-blocking CSS or JavaScript and improving the way important content is delivered.
The goal is not simply to make one element load faster. It is to improve the overall sequence through which the primary page content becomes available.
Cumulative Layout Shift measures unexpected movement of content during page loading.
A page may appear to load quickly but still provide a frustrating experience if buttons, text, images or other elements move unexpectedly as additional resources load.
Our CLS optimisation work looks for common causes such as images without defined dimensions, dynamically injected content, advertisements, fonts and late-loading components.
We identify where layout instability occurs and recommend changes that allow the browser to reserve appropriate space before content is displayed.
JavaScript and CSS can contribute significantly to page performance when websites load more resources than users need immediately.
We identify unnecessary or inefficient resources and assess opportunities to defer, remove, reduce or optimise them.
This can involve render-blocking CSS, unused CSS, JavaScript execution, third-party scripts, code splitting and resource loading priorities.
The appropriate solution depends on the website's functionality. Removing scripts without understanding what they do can break important features, so performance optimisation should always balance speed with functionality.
The browser cannot render content until it receives the necessary information from the server.
Slow server response times can therefore affect the entire loading process and contribute to poor LCP. We investigate factors such as hosting performance, caching, CDN configuration, server-side processing and other infrastructure considerations that may be affecting response times.
Where changes require developer or hosting support, we provide technically clear recommendations that can be implemented by the relevant team.
Improving Core Web Vitals requires more than repeatedly running a speed test and implementing whatever recommendations appear at the top of the report.
01
We review available field data and laboratory testing to understand the current performance of important pages and templates.
02
A poor score is a symptom rather than a diagnosis. We investigate the technical reasons behind slow loading, delayed interactions or layout instability.
03
Not every performance recommendation deserves immediate implementation. We prioritise issues based on their impact, affected templates, implementation complexity and business importance.
04
Performance improvements often require changes to code, templates, hosting or third-party integrations. We provide clear recommendations that developers can translate into implementation.
05
After implementation, performance should be tested again to determine whether the intended improvement has actually occurred without affecting functionality.
06
Laboratory scores can change immediately after a technical update, while field data requires real user experiences to accumulate. We therefore consider both testing environments and real-world performance when evaluating progress.
PageSpeed Insights and Core Web Vitals are closely related, but they are not the same thing.
PageSpeed Insights is a testing tool that provides performance diagnostics and recommendations. It can provide both laboratory test results and, where available, real-user data.
Core Web Vitals are the user-focused performance metrics used to assess loading, responsiveness and visual stability.
A PageSpeed Insights score is therefore not the same as your Core Web Vitals assessment.
A website can have a relatively high or low Lighthouse performance score while having different field performance characteristics. This is why our optimisation approach does not focus on achieving an arbitrary PageSpeed score.
We focus on understanding what real users experience and addressing the technical causes of poor performance.
Core Web Vitals should form part of a broader technical SEO strategy.
A website can achieve good performance scores but still experience crawling, indexation, canonicalisation or internal linking problems. Similarly, a technically well-structured website may have strong SEO fundamentals while providing a poor experience because important pages are slow or unstable.
Our Core Web Vitals SEO approach considers performance alongside the wider technical health of your website.
This can be particularly important for large websites and eCommerce platforms where templates, scripts, product images and dynamic functionality affect thousands of URLs.
The aim is to create a website that is accessible to search engines, useful to users and technically efficient.
There is rarely one universal reason for poor performance.
Depending on the website, problems may originate from hosting, heavy JavaScript, large images, render-blocking resources, third-party scripts, inefficient CSS, dynamically injected content or poorly optimised page templates.
For example, a poor LCP result may be caused by a slow server response rather than the visible content itself. A poor INP result may originate from JavaScript executing long tasks in the browser. CLS may be caused by images or advertising components that do not reserve sufficient space before loading.
This is why effective optimisation starts with root-cause analysis rather than applying generic speed fixes.
Website performance should support your broader SEO objectives rather than exist as a separate technical exercise. We consider how performance improvements fit into your overall search strategy.
We use available field and laboratory data to understand performance rather than relying on assumptions about what is slowing your website.
Your development team does not need another long list of performance warnings. We focus on identifying the issues that matter most and establishing a practical order for addressing them.
The objective is not to achieve a perfect score at any cost. Performance improvements should maintain important functionality while creating a better experience for customers and supporting your wider digital objectives.
Performance issues can become more difficult to diagnose on eCommerce, enterprise and JavaScript-heavy websites.
Our SEO-led approach considers templates, site architecture and the broader technical environment when recommending improvements.
The outcome of optimisation depends on your website’s starting condition, technology, hosting environment, implementation and other factors. No responsible SEO provider should guarantee a specific performance score or ranking improvement.
Effective optimisation can help your website work towards:
Improve the delivery of the main content users need when they first access a page.
Reduce delays when visitors click, tap, type or interact with important website elements.
Reduce unexpected movement that can make pages difficult or frustrating to use.
Create a more reliable experience for users accessing your website on mobile devices and varying network conditions.
Improve the performance foundation of your website while addressing technical issues that may affect both users and search engines.
We adapt tone and complexity based on industry standards.
Poor Core Web Vitals do not always have an obvious visual cause. Your website may appear acceptable when tested manually while real users experience slow loading, delayed interactions or unexpected layout movement.
SEOCompany.me can assess your website’s performance, identify the technical causes behind Core Web Vitals issues and develop a prioritised optimisation roadmap for your team.
Improve the experience your visitors have with your website while strengthening the technical foundation that supports your wider SEO strategy.
The three current Core Web Vitals are Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS). They measure loading performance, responsiveness and visual stability respectively.
Google's current thresholds classify LCP, INP and CLS into good, needs-improvement and poor ranges. However, the objective should not be to chase a score in isolation. Performance should be evaluated using real-user data and in the context of the website's functionality and business requirements.
Improving LCP typically involves identifying what is delaying the main content from rendering. Depending on the website, this may involve improving server response time, optimising the main image, reducing render-blocking resources and improving resource loading priorities.
INP improvements generally involve reducing the amount of work the browser needs to perform during user interactions. This may require optimising JavaScript, reducing long tasks, improving event handlers and limiting unnecessary third-party scripts.
CLS can often be improved by ensuring images and other media have defined dimensions, reserving space for dynamically loaded content and preventing late-loading elements from unexpectedly moving existing page content.
Core Web Vitals are part of Google's page experience signals, but they are not a standalone ranking guarantee. Strong Core Web Vitals should be considered alongside relevance, content quality, technical SEO, authority and other ranking factors.
No. PageSpeed Insights is a performance testing tool, while Core Web Vitals are specific user-focused performance metrics. PageSpeed Insights can provide information about Core Web Vitals as well as other performance factors.
Yes. Mobile performance can be assessed separately because mobile devices and network conditions can produce different performance outcomes. Optimisation can address mobile-specific issues involving images, JavaScript, server response, layout stability and resource loading.
The timeframe depends on the severity and cause of the issues, the technology used, website complexity and how quickly development changes can be implemented. Some issues can be addressed relatively quickly, while larger technical problems may require development or infrastructure changes.
No. Performance depends on factors including hosting, devices, networks, third-party services and website technology. We focus on identifying and resolving the technical issues within the website's control rather than guaranteeing a specific score.
