Page speed

What is page speed, how to measure It, and why it’s a Google ranking metric

Page speed refers to how quickly the content on your webpage loads for users. It’s a core aspect of user experience (UX) and an important Google ranking factor. A fast-loading website keeps users engaged, reduces bounce rates, and signals to search engines that your site delivers a positive experience.

Page speed can be broken down into several components, including:

• First Contentful Paint (FCP): The time it takes for the first piece of content to appear on a user’s screen.
• Time to Interactive (TTI): The time it takes for the page to become fully interactive.
• Largest Contentful Paint (LCP): The time it takes for the largest visible content element to load.
• Cumulative Layout Shift (CLS): How much the layout shifts during loading, impacting visual stability.

Page speed isn’t just about load times, it’s about perceived performance and user satisfaction.

Why page speed matters for SEO

Google has made it clear that page speed is a ranking factor. In its Page Experience update, Google emphasised that websites providing a better user experience, including fast load times, are more likely to rank higher in search results.

Slow pages frustrate users, and Google aims to prioritise websites that offer smooth, efficient experiences. A faster page leads to:

• Lower bounce rates
• Higher time on site
• Better conversion rates

This directly impacts a website’s performance in search engine results.

Google has also introduced Core Web Vitals as key Page Speed metrics that site owners need to optimise. These metrics focus on loading speed, interactivity, and visual stability.

What Google says about page speed

Google’s official guidelines state that page speed is a confirmed ranking factor for both desktop and mobile searches. In 2010, Google created their ‘Using site speed in web search ranking’ blog post, where they stated:

“We encourage you to start looking at your site’s speed (the tools above provide a great starting point)—not only to improve your ranking in search engines, but also to improve everyone’s experience on the Internet.” — Google Webmaster Central Blog

Google’s Core Web Vitals are now an essential part of its ranking algorithm, meaning that page speed isn’t just a minor factor, it’s part of Google’s core expectations for websites.

How to measure page speed

There are several tools available to measure your website’s page speed and pinpoint areas for improvement:

1. Google PageSpeed Insights

Google’s own tool provides detailed performance reports, highlighting:

• Overall page speed score
• Core Web Vitals metrics (LCP, FCP, CLS)
• Suggestions to improve load times

2. Lighthouse

Lighthouse is an open-source tool provided by Google that audits your website’s performance, accessibility, and SEO. It provides a comprehensive performance score along with actionable insights.

You can access Lighthouse directly from Chrome’s DevTools.

3. GTmetrix

GTmetrix offers detailed insights into your website’s loading performance. It breaks down issues like large images, unoptimised scripts, and server response times.

How to improve page speed

Improving your pPage speed involves optimising several technical and design elements. Here are key steps to take:

1. Optimise images

Large image files are one of the biggest culprits of slow load times. Use tools like TinyPNG or ImageOptim to compress images without losing quality.

2. Enable browser caching

Caching allows returning visitors to load your pages faster by storing some of the site’s data locally on their device.

3. Minify CSS, JavaScript, and HTML

Removing unnecessary code can reduce file sizes and improve load times. Tools like Minifier or UglifyJS can help with this.

4. Use a Content Delivery Network (CDN)

A CDN distributes your website’s content across multiple servers around the world, reducing the distance between the user and the server.

5. Reduce server response time

Slow servers can dramatically impact your Page Speed. Choose a reliable hosting provider and optimise server settings to improve performance.

You can’t ignore page speed

Users expect instant access to information. A slow website can drive users away before they even see your content. Since Google uses page speed as a ranking factor, businesses that neglect it risk falling behind their competitors.
