Page Speed

What is Page Speed?

Page Speed (known in German as Seitengeschwindigkeit or Ladezeit) describes how quickly the content of a webpage loads and is displayed to the user. It is one of the most important factors for a good user experience and is also a confirmed ranking factor for Google. Simply put: the faster a page loads, the better, both for visitors and for visibility in search results.

It is important to distinguish between two perspectives: Page Speed measures the technical loading time, while terms like "perceived speed" describe how fast a page feels to the user. Both are related but not identical.

Why is Page Speed so important?

• User Experience: Slow pages frustrate visitors. Even a few seconds of delay cause many users to bounce before the page has fully loaded.
• Ranking Factor: Google incorporates loading speed directly into its evaluation via the Core Web Vitals. Fast pages have an advantage in search results.
• Conversion Rate: Speed directly impacts business success. Faster pages demonstrably achieve higher conversion rates, as fewer users abandon the purchase process due to waiting times.
• Mobile Usage: On smartphones, often with slower connections, good Page Speed is particularly crucial.

Page Speed and the Core Web Vitals

Google now measures page speed primarily through the Core Web Vitals, a set of specific metrics for user experience. Particularly relevant for loading speed is the Largest Contentful Paint (LCP), which records when the largest visible element of a page has loaded. A good LCP value is under 2.5 seconds. Page Speed and Core Web Vitals are therefore closely linked: the Core Web Vitals are the measurement system Google uses to evaluate the speed and quality of a page.

What slows down a webpage?

The most common causes of long loading times are:

• Large, uncompressed images: By far the most frequent bottleneck.
• Excessive or unoptimised code: Bloated JavaScript and CSS that block loading.
• Slow hosting: An overloaded or underpowered server delays content delivery.
• Too many plugins: Especially with WordPress, many extensions quickly add up to noticeable loading times.
• Lack of caching: Without browser caching, files must be reloaded on every visit.

How can you improve Page Speed?

• Optimise images: Compress images and deliver them in modern formats like WebP or AVIF. This usually has the greatest impact.
• Use browser caching: So returning visitors don’t have to reload files.
• Minimise code: Remove unnecessary code and compress JavaScript and CSS.
• Implement lazy loading: Load images and content only when they enter the visible area.
• Content Delivery Network (CDN): Deliver content faster via globally distributed servers.
• Choose fast hosting: A high-performance server is the technical foundation.
• Reduce plugins: Deactivate and remove unnecessary extensions.

How do you measure Page Speed?

Several free tools are available for analysis:

• Google PageSpeed Insights: Provides a score for a single URL along with specific optimisation suggestions, separated for mobile and desktop.
• Google Search Console: Shows the status of all pages in the Core Web Vitals report based on real user data.
• Lighthouse: Integrated into Chrome DevTools, ideal for detailed analyses during development.

An important note: These tools distinguish between lab data (simulated tests) and field data (real user experiences). For Google’s evaluation, field data is decisive.

Conclusion

Page Speed is one of the most effective levers in online marketing because it impacts multiple areas: user experience, ranking, and conversion rate. Google evaluates it via the Core Web Vitals, particularly the LCP. The biggest improvements are usually achieved through optimised images, active caching, and good hosting. Since loading time can be easily measured with free tools like PageSpeed Insights, every website operator should regularly check and optimise it. The effort is worthwhile, as fast pages convince both visitors and search engines.
