How much does speed affect SEO and conversions?

In an increasingly competitive digital environment, website loading speed has become a crucial factor not only for search engine rankings, but also for conversions and user experience. It's not an exaggeration to say that a single extra second can mean one less sale..

Why does speed matter so much?

Google has confirmed that speed is a ranking factor on both desktop and mobile devices. But beyond SEO, it also has a direct impact on user behavior:

• Bounce rate increases: If a page takes more than 3 seconds to load, over 50% of users will leave before even seeing it.
• Conversions drop: A 1-second delay can reduce conversions by 7%, according to studies by Akamai.
• Brand perception suffers: A slow site signals a lack of professionalism and low reliability.

Speed optimization: Essential techniques

To improve performance, it’s essential to implement a series of practices and tools that reduce loading time and increase efficiency:

1. Image Optimization

Images are usually the heaviest resource. Use formats like WebP and techniques such as lazy loading..

2. Code Minification

Reduce the size of CSS, JavaScript, and HTML files by removing spaces, comments, and unnecessary lines. Tools like Terser or UglifyJS are ideal for this.

3. Use of Cache and CDN

Smart caching and a CDN (Content Delivery Network) allow your content to be served faster from locations closer to the user.

4. Avoid Render-Blocking Resources

Reorder your scripts and stylesheets so the main content loads first. Use async and defer attributes in your tags <script>.
