Core Web Vitals Optimisation Services

Core Web Vitals are a set of performance metrics used by Google to evaluate the speed, responsiveness and visual stability of a website.

When these metrics fall below recommended thresholds, websites can experience reduced search visibility and poor user experience.

MarkIT Space provides Core Web Vitals optimisation services to diagnose and resolve the technical issues affecting website performance.

What Core Web Vitals Measure

Core Web Vitals focus on three key performance metrics that affect how users experience a webpage.

Largest Contentful Paint (LCP)

Measures how quickly the main content of a page becomes visible.

Interaction to Next Paint (INP)

Measures how responsive a page is when users interact with it.

Cumulative Layout Shift (CLS)

Measures visual stability and whether page elements move unexpectedly during loading.

Improving these metrics helps ensure websites load quickly, respond smoothly and provide a stable user experience.

When You Might Need Core Web Vitals Optimisation

Core Web Vitals optimisation may be needed if:

  • Google Search Console reports poor Core Web Vitals
  • PageSpeed Insights identifies performance issues
  • your website loads slowly on mobile devices
  • layout elements shift while the page loads
  • interactive elements respond slowly to user input
  • site performance has declined after updates or redesigns

Common Causes of Core Web Vitals Problems

Many performance issues are caused by underlying technical factors within the website.

Common causes include:

  • large or unoptimised images
  • inefficient JavaScript execution
  • excessive third-party scripts
  • render-blocking CSS or scripts
  • poorly configured caching
  • slow server response times
  • WordPress plugin conflicts affecting performance

Identifying the root cause of these issues is essential for improving Core Web Vitals.

How the Optimisation Process Works

Step 1 – Performance Analysis

The website is analysed using performance tools and manual technical review to identify the factors affecting Core Web Vitals.

Step 2 – Issue Diagnosis

The underlying technical causes of performance problems are investigated, including scripts, images, server configuration and theme or plugin behaviour.

Step 3 – Performance Optimisation

Targeted improvements are implemented to address the identified issues and improve page speed, responsiveness and visual stability.

Step 4 – Testing & Verification

Performance improvements are verified using testing tools and monitoring to confirm that Core Web Vitals metrics have improved.
