How to Improve Load Time: Why Your Website Is Slow (and What to Do)

Google measures load time as part of Core Web Vitals and factors it directly into ranking. More importantly: studies show bounce rate rises sharply once load time passes three seconds - especially on mobile.

The most common causes

Uncompressed images

A single 5 MB photo straight from the camera can slow down an entire page. WebP format and compression typically reduce file size by 60-80% with no visible quality loss.

Missing browser caching

Without caching rules, the browser reloads every file on every visit instead of storing it locally.

Too many scripts and plugins

Every extra tracking script, chat widget, or plugin loads its own code - this adds up quickly.

Render-blocking JavaScript

Scripts without async or defer in the head block page rendering until they're fully loaded.

Slow hosting

Cheap shared hosting with many other websites on the same server is a common, often overlooked cause.

A checklist you can act on today

• Compress images before uploading (e.g. with Squoosh or TinyPNG)
• Enable lazy loading for images below the fold
• Uninstall unused plugins instead of just deactivating them
• Set up a caching plugin or CDN
• Load non-critical scripts with defer
