Core Web Vitals guide for 2026
Check your website's speed
Find out how fast your site is, what Core Web Vitals are, and how hosting affects speed. Free tools and optimization tips.
How to test a website's speed?
Test speed with free tools: Google PageSpeed Insights, GTmetrix, WebPageTest, Pingdom. Measure Core Web Vitals: LCP (under 2.5s), INP (under 200ms), CLS (under 0.1). To speed up: optimize images (WebP/AVIF), enable LSCache or WP Rocket, use Cloudflare CDN, minify CSS/JS, lazy loading, HTTP/3. BeoHosting LiteSpeed Enterprise is 12x faster than Apache — a drastic speed boost.

Open toolWhat are Core Web Vitals?
Core Web Vitals are three key indicators of user experience that Google has used as a ranking factor since 2021.
LCP
Largest Contentful Paint
Measures how quickly the largest visible element on the page loads (image, video, or block of text).
Use next/image optimization, CDN, and LiteSpeed caching for faster image loading.
INP
Interaction to Next Paint
Measures how quickly the page responds to user interaction (click, tap, key press).
Reduce JavaScript, use code splitting, and avoid heavy JS on the main thread.
CLS
Cumulative Layout Shift
Measures visual stability — how much elements move while the page loads.
Always set width/height for images, use font-display: swap, and reserve space for dynamic content.
How does hosting affect speed?
The hosting server is the foundation of your site's speed. Here's how much each factor contributes to overall performance.
Hosting server and infrastructure
40%Server type (HDD vs NVMe SSD), data center location, web server software (Apache vs LiteSpeed), and amount of RAM/CPU resources directly affect TTFB and content delivery speed.
Image and media optimization
25%Unoptimized images are the most common reason for slow sites. WebP/AVIF format, lazy loading, srcset for responsive images, and CDN for delivery — all this can reduce page size by 50-80%.
JavaScript and CSS
20%Too much JavaScript blocks page rendering. Minification, tree shaking, code splitting, and deferred loading of non-key scripts (defer/async) dramatically improve interactivity.
Caching and CDN
15%Browser cache, server-side cache (LiteSpeed Cache, Redis, Memcached), and CDN networks deliver content from the closest location to the user, reducing latency.
Why are BeoHosting sites the fastest?
Our infrastructure is optimized for maximum speed. Here's what you get with every plan.
LiteSpeed Web Server
Up to 12x faster than Apache. Built-in HTTP/3, Brotli compression, and LSCache for WordPress. All BeoHosting plans use LiteSpeed.
NVMe SSD drives
NVMe drives are up to 6x faster than standard SSDs and up to 40x faster than HDDs. All our servers exclusively use NVMe storage.
REDIS + Memcached
In-memory database caching. Reduces dynamic page load time from 200ms to 20ms. Available on WordPress PRO and Business plans.
HTTP/3 + Brotli
The newest protocol for faster data transfer. Brotli compression is up to 20% more efficient than Gzip. Automatically enabled on all plans.
Cloudflare CDN integration
Global CDN network with 300+ PoP locations. Content is delivered from the nearest point to your visitor, reducing latency to a minimum.

(+381) 60 3535 720How do I check the speed of my site?
Use Google PageSpeed Insights (pagespeed.web.dev) — enter your site URL and you'll get detailed results for mobile and desktop devices. Pay attention to Core Web Vitals scores (LCP, INP, CLS). You can also use GTmetrix or WebPageTest for additional insights.
How fast should a site load?
Google recommends a site load in less than 2.5 seconds (LCP metric). Sites that load faster than 2 seconds have a significantly lower bounce rate. For e-commerce, every second of delay can reduce conversion by 7%. Ideally, target LCP under 1.5 seconds.
Does hosting affect site speed?
Absolutely! Hosting is responsible for about 40% of total site speed. Key factors are: disk type (NVMe vs HDD), web server (LiteSpeed vs Apache), amount of RAM, CPU performance, and data center location. BeoHosting uses LiteSpeed + NVMe SSD on all plans for maximum speed.
What are Core Web Vitals and why do they matter?
Core Web Vitals are Google's indicators of user experience quality: LCP (load speed), INP (interactivity), and CLS (visual stability). Since 2021 they have been a Google search ranking factor. Sites with good Core Web Vitals scores rank better and have more organic traffic.
How does LiteSpeed help site speed?
LiteSpeed Web Server is up to 12x faster than Apache thanks to its event-driven architecture. For WordPress sites, the LSCache plugin provides full-page cache, ESI, and CSS/JS optimization without additional configuration. LiteSpeed also supports HTTP/3 and Brotli compression out of the box.
Does mobile speed affect SEO?
Yes, Google uses Mobile-First Indexing, meaning the mobile version of a site is used for ranking. Mobile speed is a direct ranking factor. Research shows that 53% of users abandon a site that takes longer than 3 seconds to load on mobile.
