Understanding website performance metrics

Website performance metrics are essential indicators that show how well your site meets user expectations. Monitoring and understanding these metrics can greatly impact user engagement, search visibility, and revenue. This guide breaks down the most important performance metrics in simple terms, so you can better understand how to use them to your advantage.

Core Web Vitals - your new best friend

Core Web Vitals are three essential metrics introduced by Google to measure the quality of user experience on your website. Here's what they mean:

Largest Contentful Paint (LCP): This metric tells you how long it takes for the largest content element (like an image or block of text) to load on the screen. Ideally, this should happen within 2.5 seconds. A fast LCP means users can start interacting with your content sooner.
First Input Delay (FID): FID measures how quickly a page responds when a user first tries to interact with it, such as clicking a button or link. A good FID is under 100 milliseconds. This metric is about how interactive your page feels – users don't want to wait for your site to react.
Cumulative Layout Shift (CLS): CLS looks at how much the visual layout of a page shifts unexpectedly while it loads. A good CLS score is less than 0.1. This metric ensures that users don't get frustrated by buttons or content moving around on the page as it loads.

Why They Matter: Core Web Vitals directly impact user experience and SEO. Google uses these metrics to determine how user-friendly a site is, affecting its ranking in search results. Meeting these benchmarks helps ensure that your site provides a fast, stable experience.

Other Key Performance Metrics

Beyond Core Web Vitals, several other metrics play a role in understanding and improving website performance:

Time to First Byte (TTFB): This measures how long it takes for the server to respond to a request from a user's browser. An optimal TTFB is under 200 milliseconds. A slow TTFB can indicate issues with server configuration or hosting quality.
First Contentful Paint (FCP): This metric tells you when the first piece of content (like a header or image) becomes visible to the user. It's a good indicator of how quickly users perceive your page to start loading.
Page Load Time: This is the total time it takes for a webpage to fully load. Ideally, a page should load within 2 seconds to keep users engaged.
Page Size and HTTP Requests: The total size of your webpage and the number of requests to the server can influence how long it takes to load. Reducing the number of HTTP requests and compressing files can help speed up loading times.

How Performance Metrics Impact User Experience, SEO, and Revenue

User Experience

Fast-loading websites create a smoother experience, making users more likely to stay and explore. Conversely, slow pages lead to higher bounce rates and user frustration. Users have limited patience, so a lagging site can result in them leaving before they even interact with your content.

SEO

Google considers site speed and user experience as part of its ranking factors. Meeting Core Web Vitals benchmarks can boost your position in search results, leading to more organic traffic. Websites that lag behind these standards may struggle to rank well, even with excellent content.

Revenue

There's a direct link between site speed and conversion rates across industries. For e-commerce sites, even a 1-second delay can result in a 7% drop in conversions, affecting sales and customer satisfaction. In the SaaS sector, slow website performance during crucial moments like onboarding or demos can reduce sign-up rates and increase churn, impacting monthly recurring revenue (MRR) and overall growth. In Travel & Hospitality, a slow-loading site can lead to abandoned bookings and missed opportunities for upselling services like room upgrades or travel packages. A faster, more responsive site keeps users engaged, supports smooth interactions, and drives higher revenue across these industries.
