What affects website loading speed and why is it so important?

Cloudflare and Google reports tell us clearly:

• Nearly half of users expect a website to load within 2 seconds and less.
• Every additional 0.5 seconds is a 20% drop in visits to subsequent subpages.
• If a site doesn't open within 3 seconds, 53% of users will leave it. Additionally, page loading speed affects SEO and site indexing in search engines. Google rewards quality, speed and usability - the better state our site is in, the better scoring we will receive.

• Page code: Let's ensure clean, optimized code, applying proven practices and relying on documentation. Avoid excessive use of scripts and plugins.
• Media size: Large images and multimedia can significantly slow down the site. Graphic optimization is key.
• Server: An efficient server, appropriately scalable and adapted to the needs of the site, helps ensure users have quick access to content.
• Minimization of HTTP requests: Fewer requests = faster loading. By taking care of the optimal amount of CSS and JS files, we limit the number of requests needed to load the page.
• Use of CDN: A Content Delivery Network (CDN) can speed up access to site resources.
• Technology applied: The use of the best libraries and solutions allows for shortening the page rendering time on the client's side at the last step before the possibility of interaction.
• Monitoring and testing: Regular checks of site performance allow for identification of problems and quick team reaction. Website loading speed is not just a technical issue, it is the foundation of our online presence. It significantly affects conversion and indexing in search engines and thus translates into the marketing budget, e.g., Google Ads or SEO that we must allocate to acquire a customer through our website. Therefore, it is worth investing in optimization and ensuring that our site works as efficiently as possible.
