How to check page speed?
Page speed testing tools:
- Google PageSpeed Insights – measures page speed and provides optimization recommendations for desktop and mobile devices.
- GTmetrix – shows loading time, page size and number of queries, as well as detailed suggestions for improvement.
- Pingdom Website Speed Test – a simple test to evaluate the website’s performance.
It is worth paying attention to:
- Time to First Render (FCP) – when the user sees the first elements of the page.
- Full charge time – the moment when all resources (images, scripts) are loaded.
- Page size – the smaller it is, the faster it loads.
The Impact of Page Speed on SEO
Page speed has This has a direct impact on SEO , as Google considers site performance as a significant ranking factor in its search algorithm. Pages that load quickly offer a better user experience, which in turn translates to lower bounce rates and longer time on page—both of which positively impact search rankings.
How does page speed affect SEO?
- Bounce rate
Slow-loading pages discourage users, who leave before viewing the content. A higher bounce rate can negatively impact a page's ranking in Google.
- Indexing and crawl budget
Googlebot indexes pages based on a crawl budget. Slow pages may be indexed more slowly, slowing the appearance of new content in search results.
- Core Web Vitals and Page Experience
Page speed is a key element of Core Web Vitals – the user experience quality metrics that Google considers when ranking.
- Conversions and User Behavior
Fast pages encourage interaction and retention, which increases engagement and the likelihood of conversions. Higher engagement positively impacts SEO because Google interprets it as a signal of valuable content.
Core Web Vitals – what are they?
Core Web Vitals is a set key user experience quality indicators on a website, which Google uses to evaluate a website's performance. They focus on three main aspects: loading speed , interactivity and visual stability pages. They are part of the larger Page Experience algorithm, which influences a page's position in search results.
The three basic metrics of Core Web Vitals
- Largest Contentful Paint (LCP) – measures the time it takes for the largest piece of content on a page (e.g., an image, headline, or text block) to fully load. The ideal LCP time is up to 2.5 seconds .
- First Input Delay (FID) – measures the time that elapses from the moment a user first interacts with a page (e.g., clicking a button or link) to the moment the browser actually responds to that action. The optimal FID value is less than 100 ms .
- Cumulative Layout Shift (CLS) – measures the visual stability of a page, i.e. how much elements move while loading. A good CLS score is below 0.1 .
The most common causes of slow page loading
- Large images and graphics – high-quality photos without compression slow down the website.
- Too many plugins and scripts – additional code increases loading time.
- Suboptimal HTML/CSS/JS code – excess or inefficient scripts slow down rendering.
- No caching or CDN – if resources are not cached or geographically separated, the page loads slower.
How to improve page speed?
1. Image optimization
- Use modern formats, e.g. WebP which are lighter than JPG/PNG.
- Compress images with online tools (TinyPNG, ImageOptim).
- Implement lazy loading to load images only when they are visible on the screen.
2. Code minimization and optimization
- Remove unnecessary scripts and plugins.
- Minify CSS and JS files – this reduces their size.
- Combine files when possible to reduce the number of HTTP requests.
3. Using CDN (Content Delivery Network)
CDN allows for faster page loading by distributing files to servers geographically closer to the user.
4. Enabling caching
Caching allows the browser to remember parts of a page, significantly speeding up loading times on subsequent visits.
5. Choosing a lightweight template or framework
- Minimalist code and optimized templates run faster.
- Limit animations and large visual plugins.
