In today’s digital landscape, website performance is critical for both user experience and SEO. One of the most important factors that impact this performance is Core Web Vitals – a set of metrics that measure real-world user experience. In this case study, we’ll look at how SMAS Magazine enhanced their website performance by focusing on Core Web Vitals.
What are Core Web Vitals?
Core Web Vitals are a set of three key performance metrics identified by Google to assess the quality of a user’s experience on your website:
- Largest Contentful Paint (LCP): Measures loading performance. A fast LCP ensures that the main content of your page loads quickly.
- First Input Delay (FID): Measures interactivity. A low FID means that the site responds quickly to user interactions.
- Cumulative Layout Shift (CLS): Measures visual stability. A low CLS ensures that the page doesn’t shift unexpectedly while loading.
SMAS Magazine’s Challenge
SMAS Magazine, a digital magazine focusing on industry news and trends, faced slow loading times and a high bounce rate. After Google announced that Core Web Vitals would play a major role in SEO rankings, they knew they had to optimize their site to maintain their audience and improve search visibility.


The Solution
SMAS Magazine implemented several strategies to improve their Core Web Vitals:
- Optimized Images: Large, unoptimized images were slowing down the page load time. SMAS reduced image sizes without sacrificing quality and implemented lazy loading.
- Improved Server Response Time: They moved to a faster hosting provider and used a Content Delivery Network (CDN) to serve content quickly to global visitors.
- Enhanced JavaScript Efficiency: They minimized and deferred non-essential JavaScript to reduce the time it took for the page to become interactive.
The Results
After these optimizations, SMAS Magazine saw dramatic improvements:
- LCP improved by 35%, with the main content loading 1.5 seconds faster.
- FID reduced by 50%, resulting in faster interaction times.
- CLS dropped by 70%, ensuring a more stable, smooth user experience.
