Today internet users are very impatient. If a site takes longer than 3 seconds to load on a smartphone, 53% of visitors close the page immediately and go to a competitor's site. In addition, Google's algorithms push fast websites higher in search results.
1. The main ways to speed up a website
- Converting images to WebP: Standard PNG and JPEG images take up a lot of space. Converting them to the modern WebP or AVIF format cuts image size by up to 70% without losing quality.
- Minifying CSS and JavaScript files: Removing whitespace and unnecessary comments from the code and combining scripts.
- Enabling caching systems (OPcache, Redis, Memcached): Instead of querying the database every time, the server delivers ready data from memory to the user in a fraction of a millisecond.
- Lazy loading: Images at the bottom of the page load only when the user scrolls to them, so the first screen opens instantly.
2. Website security and protection
Alongside speed, security is just as important: a modern SSL (HTTPS) certificate, DDoS protection through Cloudflare and regular checks against SQL injection and XSS vulnerabilities keep your site running reliably and without interruption.
